Wear OS controls for Tesla
TesserWatch
A companion phone and watch app for checking vehicle state, sending commands, and testing Owner API or Fleet API paths from the devices you already carry.
A focused Wear OS control surface for common Tesla actions, watch-face shortcuts, and phone-backed account setup.
Built for the wrist, backed by the phone.
The phone handles sign-in, selected vehicle state, account settings, and communication with the paired Wear OS watch.
Owner API mode can be enabled for legacy-command testing while still letting you switch back to Fleet API behavior.
Add TesserWatch shortcuts to compatible watch faces, or use the dedicated TesserWatch face for quick command access.
Store-ready disclosures live here.
The privacy page explains what the app uses, how Owner API tokens are handled locally, and how to request account deletion.
Users can find the account deletion path at /privacy#delete-account.
