PriceGrab

PriceGrab answers one supermarket question: <i>which of these two products is cheaper per unit?</i>

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.

<b>Designed for the aisle, not for the lab</b>
• 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.

<b>Accessibility-first</b>
• 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.

<b>Privacy by design</b>
• 100% offline. The app declares no INTERNET permission.
• No analytics, no tracking, no ads, no accounts.
• No data ever leaves the device.

<b>Open source</b>
• MIT licensed.
• Reproducible Android build, no proprietary dependencies — F-Droid friendly.
• Source code: https://github.com/mablanco/pricegrab

More compact offer entry:
• 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.
