PriceGrab Aplikasi
PriceGrab answers one supermarket question: which of these two products is cheaper per unit?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.
