PriceGrab
• When one offer wins, the result card shows absolute savings and how much cheaper it is in percent (e.g. 20% less).
• Percent is visible on screen and announced by TalkBack — not accessibility-only.
• Ties and incomplete comparisons stay quiet: no savings figures until there is a unique winner.
Type the price and quantity of offer A and offer B and the app instantly tells you which is the better deal, by how much you save per unit, and how big the relative discount is.
Designed for the aisle, not for the lab
• Material Design 3 with full dynamic-color theming on Android 12+ and a hand-tuned WCAG-AA palette on older devices.
• Locale-aware decimal input: comma in Spanish, dot in English. No more "is the period a thousands separator?" surprises.
• Inputs and result survive screen rotation and language changes.
Accessibility-first
• Every field has a localized content description that TalkBack reads.
• The result card is a polite live region: as soon as both offers parse, the screen reader announces who wins and how much you save.
• Non-color cue (a check icon) accompanies the winning offer so the design works in grayscale or for color-vision-deficient users.
Privacy by design
• 100% offline. The app declares no INTERNET permission.
• No analytics, no tracking, no ads, no accounts.
• No data ever leaves the device.
Open source
• MIT licensed.
• Reproducible Android build, no proprietary dependencies — F-Droid friendly.

• Price, quantity, and unit sit on one row at normal font size — less scrolling with two or three offers.
• At large system font (including 200%) the layout switches to two rows so nothing is clipped.
• Comparison math, units, and add/remove third offer are unchanged.
• Tap + to add a third offer (Offer C); tap − to remove it. Still starts with two.
• Winner is the cheapest per kg / L / piece; savings name the second-cheapest offer.
• Blank third card is ignored until you fill it in.
• Launcher icon artwork recentered vertically (corrected downward vs earlier cut).
