The More info sheet now lists every ranking a station qualifies for, directly under the map and above the price and distance: the same StationLabelBadge the listing rows render, in a flow layout so two or three capsules wrap to a new line rather than truncating at large Dynamic Type.
The rules are not restated. StationRanking defers to StationRecommendationBadge.badge for the Best Value gate, and takes Cheapest and Top as the flags the host list already computed for its own rows, so the sheet cannot award a capsule the row behind it withheld. A host passes one of the two, never both: Stations sends isCheapestInRange, Favourites sends isTopFavourite. No calculation, ranking, eligibility or savings logic changed.
Rename the card heading Best Value to Value breakdown, since the working behind it can end in Costs rather than a saving, and drop the green section tint so the card matches the neutral background used elsewhere in the sheet. The Saves, Break even and Costs capsules and every breakdown row are untouched.
Rename the explanation link to How does FuelBoard calculate value? It names the calculation rather than the feature, of which the Best Value gate is only the last step. The sheet's own title stays short: the full question truncated to 'How does FuelBoard...' as a navigation title at both inline and large display modes, so the row carries the question and the sheet names the topic.
Tests: 269 pass, 5 new covering capsule selection, order and sheet-vs-row agreement on Best Value.
One adaptive tone palette and one shape rule now drive every capsule on
Stations, Favourites, the detail sheet and the Key.
- CapsuleTone: the light/dark palette pairs in one place, resolved through a
UIColor dynamic provider so a List row that re-renders without rebuilding
its body still follows an appearance switch. Every pair clears 4.5:1
foreground-on-background in both appearances (4.96-6.72:1).
- AdaptiveCapsule: capsule at one drawn line, rounded rect at two or more,
radius 8 -> 10, measuring content before padding so insets cannot inflate
the line count.
- Listing verdict capsules move from white-on-muted-solid to the tinted
palette, so Saves, Break even, Costs and Closest station read the same in
the rows and in the detail sheet.
- Best Value is purple, not green: green stays reserved for a financial
saving, which is what the Saves capsule beside it means.
- Price dots standardise to 12pt in the app (widget keeps its own 6pt dot;
PriceRatingDot now takes a diameter so the difference is deliberate).
- Station labels are sentence case with their recommended symbols (medal, tag,
location.north.fill, trophy) and StationLabelKind replaces the Key's
string-literal dispatch, so renaming a label can no longer drop a row.
- Key says "Costs", matching the capsule's own headline (was "Costs more").
Favourites gains the same info button the Stations list has, last in
the trailing toolbar group so it sits to the right of Edit. It stays
visible when the list is empty, because the legend explains the prices
and labels before anything is starred — Trends and Edit still hide
with no favourites.
The legend itself is now one view, KeySheetView, lifted out of
StationsView's private computed property so both tabs present the
same sheet and cannot drift apart. It lives in StationsView.swift
because the key's row types are file-private there, which keeps the
Xcode project untouched. Stations passes its selected fuel's tint and
Favourites its active tab's, so the station-label pump badge matches
the rows on screen; everything else — detents, the two nested sheets,
and the -showKeySheet / -showBestValueInfo / -showImportantInfo QA
launch hooks — behaves exactly as before.
The listing's verdict capsule now carries white text on muted semantic
fills instead of the neutral secondary tint: Saves #45825E, Costs
#A9635B, Break even #707070, Closest #58789D.
Fixed tones, not translucent tints, because white text on a 15% tint
over a white row measures ~1.8:1. Each tone sits at a relative
luminance of ~0.18 — the band where white clears 4.5:1 AND the pill
still separates ~3:1 from both a white row and the dark card fill — so
one value each works in light and dark without a dynamic colour. The
saturated palette colours cannot carry white text at all: systemGreen
measures 2.2:1, systemRed 3.6:1.
"Save" becomes "Saves", matching the detail sheet and reading as a
statement of the outcome; amounts, symbols, padding, radius and the
shape-follows-line-count rule are unchanged. Saves and Costs share an
84pt minimum width so their trailing edges line up down the list.
The price and its capsule are now one vertically grouped element (5pt),
with the badge keeping the column's full 12pt above, so the row no
longer reads as three equal lines.
Station names cap at three lines with a tail ellipsis: unbounded wrap
let one very long forecourt name set the height of the whole row. 59 of
the 8,073 names in the dump exceed three lines and now ellipsise; the
full name is always in Station Details. Addresses still wrap freely.
The baseline pill moves onto ListingFuelSavingsCapsule so the listing
shows the same soft blue and white text as its siblings, leaving
FuelSavingsCapsule to the detail sheet, which it now alone uses.
Badges keep their tinted styling: they annotate a price rather than
report an outcome.
Verified: 261/261 swift test; Debug simulator and Release device
builds; all four fills and their white text measured from simulator
pixels in both appearances, and the detail sheet's .blue absent from
the listing entirely.
Station and Favourite rows share one capsule, so both now read
"Save / £3.10" and "Costs / £1.20 more" instead of the amount-free
"Saves" / "Costs more". "(approx.)" is appended on its own line when the
journey behind the figure was estimated. Break even carries no figure —
±£0.05 is noise — so it stays a single line unless the qualifier adds one.
- Split `listingCapsuleHeadline()` into a structured `ListingVerdict`
(headline / amount / qualifier) drawn as one Text per line, so where the
capsule breaks is decided by the data rather than by the width the price
column happened to hand it: the figure can never straddle two lines.
- The capsule's shape follows its line count: one line stays a Capsule, two
or more switch to a rounded rect at 8pt, whose corners do not crowd a
taller block the way a pill's semicircular ends do.
- The Key sheet's legend renders the same component with `showsAmount:
false`, so it demonstrates the wording without displaying the placeholder
£1.00 figure it was built from.
- The new words ("Save", "Costs", "(approx.)", "%@ more") go into
Localizable.strings so the copy editor owns them; amounts run through
FuelSavingsFormat.money and the amount line is monospaced.
- VoiceOver keeps the single-line form, since a drawn break is a pause
mid-phrase when spoken.
Tests cover the line structure for all four statuses, the estimated
qualifier and the amount-free legend. Pixel measurement on the simulator
confirms the shape rule: one line measures a radius of h/2 (a pill), two
lines measure 8pt, in both light and dark.
- Alerts: drop the alert-type picker and the Best Value alert path, so
proximity alerts always follow the cheapest station. A stored `bestValue`
selection now falls back to cheapest when loaded.
- Key sheet: the price-rating, savings, station-label and favourite wording
comes from `KeySheetContent` in Shared/FuelSavings.swift — a Foundation-only
model with tests that pin the exact meaning of each indicator — and the
sheet is built from that model rather than inline strings.
- BACKLOG: record the plan to restore Best Value proximity alerts behind one
shared evaluator (user-location baseline, a single disclosed qualification
rule, and real/Test alert parity).
- Bump CURRENT_PROJECT_VERSION to 29.
One sheet, reachable from the bottom of the Key sheet and from the bottom
of Settings, with each topic as its own card and heading:
- Fuel Prices, Fuel Availability, Savings & Best Value, Journey Estimates,
Before You Travel and Disclaimer, in that order.
- Every heading carries an SF Symbol in a fixed-width, Dynamic-Type-aware
slot, so heading text lines up across sections regardless of glyph width.
Icons take the accent colour, headings are semibold and primary, and each
description sits beneath its heading in secondary text.
- All copy lives in en.lproj/Localizable.strings keyed by the English
literal, ready for the web copy editor.
- The sheet, its trigger row and the .importantInformationSheet(isPresented:)
modifier live in one file, so any further entry point is a one-line change
and the wording cannot drift between them.
- DEBUG-only `-showImportantInfo` launch hook, chained behind the Key sheet,
for screenshotting without a tap.
The explanation sheet now carries a full-width button that closes it and the
sheet it was opened from, then lands on Settings — whose Best Value section is
the first thing in its list, so the controls are on screen on arrival. It uses
.controlSize(.large), the standard iOS button height.
Both the More info sheet and the Key sheet are presented by StationsView, and
FavouritesView presents its own More info sheet — not ContentView's monitor as
assumed — so each host closes whichever sheet it owns on the notification.
Before this, one of them stayed up over the Settings tab. The button now
announces itself half a second after its own dismissal, so the child and parent
dismissals cannot race and drop one of the two.
The Best Value card states its verdict once. The badge is now the large capsule form the sheet used to repeat on its own line, so the same headline no longer appears twice, and the comparison caption ("vs closest station" / "your baseline") sits under the capsule — on the card and on the listing rows alike. The row's size-class split, which put the caption beside the capsule at regular width, is gone, so the pair reads the same on every device.
The facts row's price now follows Settings -> Units -> Price display. It called FuelStore.priceText(price, style: .stationSign) with the style hardcoded, so a Pounds & pence user still saw the bare forecourt figure under the map. It now uses priceTextAttributed with the style passed down from the list that opened the sheet (ContentView, StationsView, FavouritesView) — the same call the listing row makes, at the same @ScaledMetric(relativeTo: .title2) 22pt so it still scales with Dynamic Type.
"How Best Value works" gains a step-by-step section in plain English: the baseline and why it is the closest station by journey, the return trip and why the extra return travel can read larger than the one-way distance, the extra driving cost, the fuel-price saving, the total and its inversion when the drive costs more than the price saves, and where the minimum saving is set. Every statement matches the arithmetic in FuelSavingsCalculator. The sheet opens at 72% instead of 42% to give it room.
No calculation, ranking, wording or data source changed: comparisonLabel, priceTextAttributed and the shared FuelSavingsResult are the same calls they were.
Two columns split by a 1pt hairline: identity on the left at a fixed 52%
share so rows line up when scrolling, price and savings on the right,
leading-aligned on one axis with the price dominant. The favourites star
sits under the station logo, freeing the width the pounds-and-pence price
needs to render in full rather than scaled or truncated.
Badges stay tinted rather than filled — BEST VALUE green, CHEAPEST blue,
none for nearest — and the verdict capsule is one shared view across the
listing, the detail sheet and the compact summary, so wording and colour
cannot drift between them.
Best Value's minimum saving moves from Alerts to Settings, Fuel Savings,
beside the fill size and MPG that produce the saving; the Alerts tab reads
it back instead of offering it twice. Its options are now 50p steps to £5
(was 50p/£1/£2/£5), so £2.50 and £3 are reachable, with a test pinning the
step, the ceiling and the store's string round-trip.
The verdict capsule scales to 0.7 before truncating. Measured on a 393pt
screen its copy is handed ~69pt while "Closest station" needs ~90pt, so the
old 0.8 floor could not reach it and rows showed "Closest stati..." instead.
Verified: Debug build clean, swift test 249/249.
The relay's price_updated is the maximum price_last_updated across the grades it maps, so it cannot vouch for the selected grade: stop using it to score, gate or warn about Best Value.
- FuelPriceFreshness is now station-level and display-only: one age per station, fresh/outdated/unknown/invalid, "May be outdated" past 30 days, with future-tolerance and non-finite guards.
- Best Value restores the closest-station-selling-the-selected-fuel baseline and its savings ranking; eligibility gating, eligible-first sorting and the unavailable banner are gone.
- Price age appears in the More info sheet only - no listing-row warnings, no extra banners.
- Copy reverted from "closest eligible station" to "closest station"; stale price-confidence strings removed, "May be outdated" added.
- Dormant per-grade timestamp plumbing removed, and regression tests added for every fuel type, missing/invalid/future stamps and the bundled offline dump.
- Station detail now separates the station's own report age from the
selected fuel's update time, so a recent station-wide report no longer
reads as an old price.
- Warning copy names the fuel and says which side is weak: the station's
price is not individually dated, or the baseline's is. The misleading
"unverified or older than 7 days" line is gone.
- Wording stays "Closest" throughout; new copy uses Unleaded / Premium /
Diesel rather than the internal grade codes.
- Localisation: new and updated keys for the added copy.
The More info row went inside the Best Value card's `if let fuelSavings`, but the
Key sheet row was left ungated, so it stayed visible with Best Value switched off.
It is now gated on `fuelSavingsSettings.isConfigured` — exactly the condition
`savingsForStation` uses, i.e. the same gate as the card — so the two rows appear
and disappear together.
Verified on the simulator by toggling Best Value in Settings and scrolling the Key
sheet to its end (four drags, sheet still up and its footer in view each time):
- OFF: the row is absent at every scroll position, and the More info sheet shows
neither the card nor the row;
- ON: the row is present, and the More info card and its row are both back.
210 tests pass; Release builds.
The explanation used to be a section inside the Key sheet. It is a standalone
HowBestValueSheet now, opened from a tappable row with a chevron: at the bottom of
the Key sheet, and at the bottom of the More info sheet below the Best Value card.
Gating: the More info row sits INSIDE the same `if let fuelSavings` as the card it
follows, so it disappears with the feature. Verified with Best Value toggled off in
Settings: the More info sheet then shows neither the card nor the row. The Key
sheet row is deliberately ungated — that sheet is the legend and is reachable
whatever the feature is doing.
Copy is unchanged: the same Localizable.strings strings are reused, and the old
section header became the sheet's title. A DEBUG-only `-showBestValueInfo` hook
opens the sheet without a tap.
The third sort segment, the caption line it drives on the Stations tab, and the
Settings sentence about sorting now read "Best Value" — that is
SortMode.worthTheDrive.displayName plus the two copy sites that name the sort.
The feature that backs it keeps the name "Worth the Drive": the Settings toggle
("Enable Worth the Drive"), the Fuel Savings section header and footer, the sheet
header "Worth the drive?", the "Worth the Drive unavailable: …" text and
FuelSavingsStatus.worthTheDrive's own wording are all unchanged.
The enum's raw value stays `worthTheDrive`, so stored sort preferences and widget
configs keep decoding — only the label moved.
3 new tests pin the three sort names, the stability of the raw values, and the
fact that the feature's own wording did not change (172 total, 0 failures).
Verified on the simulator: the Stations segmented control reads
Closest | Cheapest | Best Value.
The two Fuel Savings figures and the in-list fill-up control were text
fields. A typed figure could sit outside the slider's own bounds, so the
control and the number it claimed to show could disagree, and the decimal
pad needed a Done button to escape.
- Settings: "Average fuel economy" and "Typical fill-up" are now sliders
with a read-out ("45 MPG", "£40" / "40 L") in place of the field. The
warning copy reads "Set a realistic..." rather than "Enter...".
- FuelSavingsAdjustmentView (shared by the Stations Worth-the-Drive header
and the Favourites tab) drops its text field and gains the same read-out;
the typed-value machinery and the -focusFillAmount QA hook go with it.
- Slider bounds live in FuelSavingsCalculator (fillAmountSliderRange/Step,
mpgSliderRange/Step) so the Settings control and the in-list control can
never offer different ranges, and the fill-up slider range stays inside
the calculator's validity ceiling (asserted by test).
- Two tests pin those invariants: every slider position is a valid amount,
and both MPG bounds are valid MPG values. 155 tests, 0 failures.
- Comments that described the removed fields were updated; the keyboard
Done-bar plumbing is kept (no numeric field remains in the app, so it can
no longer fire) rather than deleted, so any field added later still has an
escape route.
Verified on the simulator: Settings shows "Average fuel economy / 45 MPG"
with no field, and the Worth-the-Drive fill-up control shows the unit picker
with a "£40" read-out and a slider. The Settings "Typical fill-up" row sits
below the fold on every simulator available here (and synthetic input cannot
scroll it), so those pixels are unverified.
Calculation audit (brief config: 30 MPG imperial, £60 fill-up, baseline
Rontec Shelf 171.9p at 0.4 mi):
- One mile<->kilometre constant pair (kilometresPerMile 1.609344,
metresPerMile 1609.344) replaces the mixed 1609.34 / 0.621371 / 1.60934
used in the savings path. Effect ~2 ppm (invisible), but the conversions
are now auditable in one place.
- New FuelSavingsCalculationAuditTests (20 deterministic tests, no live
MKDirections) pins the brief's three stations - Tesco 170.9p/2.0 mi,
MFG Hare & Hounds 172.9p/2.8 mi, PGG Napoleon 171.9p/2.8 mi - plus
imperial-vs-US gallon, MPG and budget scaling, the break-even tolerance
boundary, the nearer-candidate clamp, route-unavailable, mixed-basis
estimates and display-rounding boundaries.
- Formula unchanged, and verified correct: fixed quantity (budget / baseline
price), pump saving, round-trip extra distance clamped at zero, travel fuel
priced at the candidate station, +/-5p break even, baseline labelled
"Closest station", sorting on the unrounded net saving. The brief's "£0.18"
for Tesco is the rounded 1 dp extra-distance caption (2.02-2.05 mi reads as
"2.0 mi"), not a rounding bug in the money.
UI (uncommitted since d7a0ecb):
- Done bar drawn in the bottom safe area from keyboard notifications:
.toolbar(placement: .keyboard) is device-dependent (present on the 15 Pro,
absent on the SE on the same iOS build).
- Favourite star in the More-info heading, wired to the same fuel-scoped
toggle as the listing rows at all three call sites.
- CHEAPEST/TOP badge moved above the price so it reads as part of it.
- Listing rows carry the real session fill-up amount instead of a hard zero
(the compact banner does not print it today; a future row layout would).
153 tests, 0 failures. Simulator and device builds succeed.
Optional Fuel Savings feature (off by default): vehicle MPG in UK imperial gallons, fill amount in pounds or litres, persisted through the existing keychain/app-group store. Ranks the WHOLE station pool by estimated net saving (fuel-price saving at each pump minus the extra return-trip driving cost) using MapKit road distances with a straight-line fallback marked (est.).
The closest station with a valid price for the selected fuel is the comparison baseline and is labelled "Closest station"; other rows read "Save £X.XX after travel" / "£X.XX worse off after travel" / "Break even". Labels live in the shared model so they are unit-tested. The TOP badge still marks the cheapest pump price and reads "CHEAPEST" when the list is ranked by net saving.
Road routing now prioritises the Worth-the-Drive candidates plus the baseline and merges cache entries instead of replacing them, so far-out stations get real routes rather than permanent straight-line estimates. Numeric fields gain a Done button above the keypad (decimalPad has no Return key); the fill-up control is hidden unless the feature is configured; Favourites shares one session fill amount with the station list. 131 tests.
Settings → Units gains a Tap station picker: Open map (default,
historic behaviour — tap opens Apple Maps directions) or More info
(tap shows a detail sheet with name, address, distance from current
location, and a Directions button). Applies to Stations and
Favourites tabs; persisted keychain-first as
fuelboard.stationTapAction. Stations footer hint follows the setting.
Move FuelType.tintColor (green=unleaded #30D158, yellow=premium #FFD60A,
cyan=diesel #64D2FF) into Shared/FuelStore.swift so the app, widget, and
Live Activity all read one definition (was app-only in StationsView, so the
widget couldn't see it). Tint the Live Activity rich card pump icon and the
Dynamic Island compactLeading pump by context.state.fuel.tintColor.
Sheet grows from .medium to .fraction(0.6) so the footer ('Colours
match each station's rating on the list') clears the bottom edge with
comfortable margin (verified: footer clearance +33pt). Sheet background
switched from the translucent default to a solid
systemGroupedBackground via .presentationBackground so the stations
list no longer shows through.
The two bottom cards (TOP, star) previously had no padding — their
background hugged the text. Add .padding(.horizontal, 14).padding(.vertical, 12),
matching (slightly exceeding) the RAG cards' vertical padding so the
info cards read as proper cards.
Price-rating legend now renders as five accent cards (tip-section style):
Best value (green, checkmark) / Okay (orange, equal) / Pricey (red,
exclamation) each with a RAG dot + threshold (≤1.5p / ≤4p / >4p) on the
right in the row's accent colour; TOP (blue capsule) and star (yellow)
as accent cards below a divider. Footer: 'Colours match each station's
rating on the list'. Copy split into title/blurb keys in Localizable.
Sheet chrome (medium detent, Done, info button) unchanged.
The N/TOTAL stations-updated explainer now sits in a plain caption Section
cell at the bottom of the tab (font .caption, secondary) — matching the
Favourites tab's bottom callout instead of rendering as a section footer.
The header section was removed entirely — the tab now opens with Fuel type.
The explainer lives as a section footer at the bottom of the tab:
- Cheapest: 'Cheapest Unleaded within 5 miles — 46/8022 stations updated ·
tap a station for directions.'
- Closest: 'Closest Unleaded stations — nearest first, best value within
5 miles · 46/8022 stations updated'
- no-location variant keeps mode + tap-for-directions hint
Numerator = stations in the current list pool (as before); denominator =
full UK station total from the last chain fetch (loadStationCount, 8,022
mirror snapshot) — ratio hidden until the first fetch lands.
- FuelTypeSegmentedPicker promoted to shared (was private in StationsView)
and parameterised by fuel list so Favourites passes only fuels with favourites
- Favourites tab swaps native .segmented picker for the capsule control with
green/purple/grey fuelpump icons, matching Stations
Fixing the bug where favouriting an Unleaded entry also created a Diesel
favourite. Favourites are now [FavouriteEntry] = (station, fuel) pairs:
- Starring a row pins it only for the fuel being viewed
- Favourites tabs show only fuels that actually have favourites
- Geofence monitor gives priority slots only to favourites matching the
monitored fuel
- Tests updated + new fuel-scoping test (31/31 passing)
The 'N stations within X' caption now lives in the header explainer
(Closest/Cheapest + radius + count on one line); the Distance section
shows just the picker.
- FuelType labels: 'Unleaded (E10)'/'Premium (E5)' -> 'Unleaded'/'Premium'
- New DistanceUnit (miles/km) preference; all app + widget distances,
radii and alert text convert/display in the chosen unit
- Settings tab (4th tab): segmented miles/km picker, 'Show introduction'
replay button (onboarding moved out of Alerts tab), StoreKit tip £4.99
- ProximityMonitor + widget notifications use the chosen unit
- Tests: label expectations updated, DistanceUnit conversion + format tests
