TendTag: Home Care Tags
Home care that lives where the work happens.
Pair a care card with an NFC tag on the furnace, smoke alarm or fridge filter. Tap the tag to see what it needs, when it is due and what was done last. Everything stays on your phone.

One paid download. No ads, subscriptions or in-app purchases.



What it does
Tap a tag, see the job
Each tag opens its card: instructions, next due date and local history. Tapping doesn't mark the work done; TendTag waits for you to confirm.
Due dates that follow reality
The next due date starts from when you actually did the work, early or late. See upcoming, due and overdue care at a glance.
Start from a template
Use one of six editable templates or a custom card. Add a room, instructions, recurrence and an alert time.
Local by design
No account, no cloud and no Internet permission. The tag holds only a random identifier. Back up with a file you export and keep.
A gentle reward
Each completed job earns a tendie to spend on your Mossling, a small companion that never dies, leaves or locks features.
Optional reminders
Local, best-effort notifications when Android allows them. Cards and due dates work with reminders off.
Before you buy
- TendTag needs an Android phone with NFC. It does not run on iPhone.
- NFC tags are not included. Use writable NDEF tags: NFC-A/B (ISO 14443) or NFC-V (ISO 15693). NFC-F / Type 3 is not supported.
- Tag compatibility and scan position vary by phone, tag and placement. TendTag does not promise to work with every model.
- There is no account, sync or cloud backup. Export a backup file yourself; clearing app storage, uninstalling or losing the phone erases anything not exported.
- Reminders are optional and not guaranteed. Android may delay or block them.
- TendTag is a record and reminder tool. It does not monitor equipment or replace manufacturer instructions, safety guidance or inspection.
