Google's Gemini platform will replace Assistant on Wear OS devices through an app update. This transition was hinted at in January, with the latest Assistant app version (1.18.x) revealing strings related to Gemini. Users can activate Gemini by holding the side button or using the "Hey Google" hotword. Gemini's capabilities will be similar to Google Assistant, allowing users to set alarms, timers, and message contacts, though it's unclear if it will integrate with Gmail or Google Maps. Location and Voice Match settings will remain unchanged, and the Wear OS Tile feature will still be available. The launch may coincide with a new flagship watch.
