TK-Retter
Master your freezer: print labels, find supplies, waste less.
TK-Retter turns your freezer into an inventory. Home-frozen food gets a label with a QR code – printed on the Nelko P21 label printer – and store-bought products are added by barcode. The app suggests what to rescue next and helps you thaw it.
What the app does
Labels for containers
Print straight to the Nelko P21 via Bluetooth – contents, date, and QR code. Batches: several containers, several labels.
Scan instead of search
Scan the QR code and the container is checked out. Store-bought packs are recognised by their barcode.
Rescue today
Suggestions by date and age – or roll the dice for tonight's dinner.
Thawing with a plan
Tips per category and a notification when it's time.
Opened packs
Track fill levels – opened packs come first.
Widgets
Rescue suggestions on your Home and Lock Screen.
Privacy
- Your inventory stays on your device.
- Barcode scans only send the number to Open Food Facts.
- No account, no ads, no tracking.

Please note
TK-Retter is not affiliated with the maker of the Nelko P21. Label printing works with the Nelko P21; you can use the inventory without a printer, too.
