Offline wallet
Cards that work when signal does not.
Every saved card is available on-device. The app is designed for checkout moments where speed matters and network retries are not welcome.
Features
TesserApp is built around one job: keep your loyalty cards ready without turning the app into another account, feed, or tracking surface.
Barcode first
Clean scans, fast access.
Keep barcodes readable with a dedicated white display area, favorites for frequent cards, and quick search for the rest.
Private by default
No account required.
No login, no ads, no third-party analytics SDK, and no tracking profile. Your wallet stays yours.
Everyday devices
Made for iOS, Android, and Apple Watch.
Keep cards available on your phone and bring key wallet actions to your wrist when you need them fastest.
Nearby suggestions
Cards for shops around you.
TesserApp can suggest matching cards for nearby shops within a 50m radius, so the right card surfaces before you search.
Photo cards
More than barcodes.
Store cards without barcodes too, by saving front and back photos for things like IDs, memberships, or paper passes.
What You Can Expect
- Add loyalty cards by scanning a barcode or entering details manually.
- Store cards locally so they remain usable without a data connection.
- Search and favorite cards for quick checkout access.
- Use nearby shop suggestions to surface relevant cards within a 50m radius.
- Store non-barcode cards with front and back photos.
- Use TesserApp across iOS, Android, and Apple Watch.
- Keep card names tidy with normalization rules designed for real store names.
- Use a focused barcode screen that keeps scanning reliability front and center.
