Yes, completely. All comparisons, unit conversions, and barcode scanning run entirely on-device using Google ML Kit. You can use GroceryComp in a store with no Wi-Fi or cell signal. The only features that use internet are AdMob ads (free tier) and the Google Play billing flow when purchasing Pro.
GroceryComp supports all common grocery units: weight (g, kg, oz, lb), volume (mL, L, fl oz, gal), and count (items). It automatically converts mixed units — so you can compare a 500g box directly against a 17.6 oz box and get an accurate per-unit price.
The barcode scanner uses Google ML Kit on-device text and barcode recognition to read the product barcode (UPC-A, EAN-13, QR, and others). It automatically fills in the product name field on the comparison screen. No data is sent to any server — everything happens locally on your phone. Barcode scanning is a Pro feature.
Yes. Open the app, tap the hamburger menu icon to open the navigation drawer, and tap 'Upgrade to Pro'. On the upgrade screen, tap 'Restore Purchase'. As long as you are signed in to the same Google account that made the original purchase, Pro will be restored at no charge.
All comparison data, saved lists, and history are stored locally on your device using an encrypted Room database. GroceryComp does not collect, store, or transmit any personal data. Ads are served by Google AdMob (free tier only), which may use device advertising identifiers per Google's privacy policy. See our Privacy Policy for full details.
GroceryComp requires Android 8.0 (Oreo, API level 26) or higher. It is optimized for Android 14 and 15 (API 34–35) and is tested on phones and tablets.
