Which watches does catetin.ai support?

Apple Watch with watchOS 10 or later, paired with an iPhone, and Wear OS watches with Wear OS 4 or later, paired with an Android phone. The Apple Watch app comes with the iPhone app, and the Wear OS app is on Google Play.

Do I need my phone nearby to log an expense?

Only once: sign in to catetin.ai on your phone and open the app so it can send your groups and sign-in to the watch. After that, the watch can log expenses on its own over Wi-Fi or LTE.

How do I confirm an expense on the watch?

After you log an expense, the AI's answer appears on the watch with suggested replies. Tap a reply such as Yes, create to confirm, and the transaction appears in the app. Each expense uses 1 chat quota.

Can I change the group or period on the watch face?

Yes. On Wear OS, the Tile has buttons for the group and the period. On Apple Watch with watchOS 11 or later, the rectangular complication has group › and period buttons. The watch app, Tile and complications always show the same group and period.

Why does the watch show •••••• instead of amounts?

Biometric login is turned on in the phone app, so catetin.ai hides amounts on the watch, the same as on the widget.

Use catetin.ai on Apple Watch and Wear OS

The catetin.ai watch apps show each group's spending for today, this week, this month or this year, and let you log an expense from your wrist by voice or keyboard. The AI's answer appears on the watch, so you can confirm it there too. The Apple Watch app comes with the iPhone app, and the Wear OS app is on Google Play.

One group and period for the whole watch

The watch app, the complications, the Smart Stack widget and the Tile share one selection. They start on the phone's group and period. When you change the group or period on the watch, for example on a page, with the period button, or with the buttons on the Tile or rectangular widget, all of them follow. When you pick another group or period in the phone app, the watch follows the phone again.

Sync and privacy

The numbers update when the phone app syncs, for example after you or another group member logs a transaction.
If the watch shows “Open catetin.ai on your phone to sync”, open the app on your phone once while the watch is connected.
If biometric login is turned on, amounts on the watch are hidden as ••••••.
When you log out on the phone, the watch signs out too and deletes its data.
