Stop losing receipts in drawers and email attachments. Keepsy photographs your receipts and reads the store, date, and price automatically — right on your phone, no account or internet connection required. It quietly tracks each item's warranty and return window, then reminds you a few days before either one closes. HOW IT WORKS • Snap a photo of any receipt • On-device text recognition reads the store, date, and price for you • Set a warranty length and return window (or use the defaults) • Get a reminder before the deadline — not after WHY IT'S DIFFERENT • Receipt text recognition runs entirely on your device — nothing is ever uploaded • No account needed • Clean, fast, no ads FREE VS PRO The free plan tracks up to 3 items. Keepsy Pro removes that limit and adds CSV/PDF export of your receipts. (Cloud backup is planned for a future update.)

Verdict

The call

The clearest difference is update cadence: Keepsy Receipts at every 2 days against Proofreader AI Grammar Checker's fortnightly. Keepsy Receipts also leads on rating (5.0 vs 4.7). Proofreader AI Grammar Checker's advantage is ratings volume (3.3K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
