Watt Time, previously known as Tesla Time, is an app developed by Joshendy that allows you to control and monitor your Tesla vehicle directly from your Wear OS watch. With an extensive range of features, Watt Time turns your watch into an NFC key for your Tesla, allowing you to easily summon and smart summon, lock/unlock, open the frunk and trunk, honk the horn, and flash the lights. You can also remotely start your car, start/stop charging, and open/close the charging port. If you own more than one Tesla, you can select from multiple vehicles to control.
