FastGroceries - Smart shopping is your in-store companion: lists organized by aisle, timed shopping routines with optional price capture, budget views, trip history and analytics, and barcode-based nutrition powered by Open Food Facts. Optionally sync your list with a partner via notifications after pairing.

My List
Build your list by category (aisle)—each with a name and color. Collapse categories, hide checked items per section, and use inline add with suggestions. Tap to check items off; long-press to edit, set auto restock on a schedule, or remove. See streaks, upcoming reminders, and optional prices on the list (when enabled in Settings). After pairing, use Sync to send your list to your partner (they confirm via notification).

Shopping routine
Start from an aisle, a saved routine, or a reminder. The routine screen keeps you in flow: timer (with optional auto-start), check off items, enter prices with hints from past trips, skip what you’re not buying, and get budget alerts if you set a threshold. End to save the trip to history; cancel to discard. Return from the scanner with scanned items added to the active routine when you use that flow.

Routines tab
Save a snapshot of an aisle as a routine, then start it anytime from the Routines tab. See when it was last run and manage cards from My List’s “Save as Routine.”

Budget
See list overview, spending history (when you have completed trips), progress (checked vs remaining), and estimates when prices exist—plus line items in cart and what’s still needed, by aisle where it helps. Amounts follow your currency settings (symbol, position, spacing).

History
Trip count, session time stats, an activity heatmap, most bought items, item price views, a price tracker for items with enough trip data, and a full trip list with totals and sessions over time. Tunable in Settings (ranges, heatmap window, retention).

NutriLens (scanner)
Scan common retail barcodes. View product details from Open Food Facts: nutri-score, macros, nutrition panels, and tabs for more detail. Explore alternatives and help improve data with Robotoff questions when shown. Add to list (default Scanned aisle, or the active routine aisle when you’re in a routine).

Settings
Theme and accent, currency (including custom), units, routine options (auto-start timer, budget alert), history controls, reminders (including routine deep links), list sync pairing (QR) on iOS/Android, export trip history, reset list or clear history, and feedback by email. Data stays on your device unless you use sync or feedback as described in the app.
