How to Open Apps with Gemini Voice Commands on Smartwatch

Name: Google Pixel Watch 4
Brand: Google
Availability: PreOrder
Rating: 4.8 (1250 reviews)

Gemini makes app launching on smartwatches effortless through simple voice commands, eliminating the need to navigate through small touch interfaces or app menus. This feature works with any apps installed on your smartwatch and is particularly useful during workouts or when your hands are occupied.

Basic App Opening Commands

Simple Voice Commands - The simplest method is using "Open [app name]" commands. For example, "Open Spotify," "Open Samsung Health," or "Open Timer" will launch the respective applications directly. Gemini recognizes both official app names and common abbreviations, so "Open Gmail" and "Open email" both work for email applications.

Workout and Fitness Apps

Exercise-Focused Control - This functionality is especially valuable for fitness apps during exercise. Commands like "Open Strava," "Open Fitbit," or "Open workout tracker" allow you to start fitness tracking without breaking your exercise flow or fumbling with small watch buttons.

Media and Entertainment

Content Access - For media control, you can open music apps with "Open Spotify," "Open YouTube Music," or "Open podcast app." This integrates well with Gemini's media playback controls, allowing seamless transition from app opening to content control.

Productivity Apps

Daily Utilities - Open productivity and utility apps with commands like "Open calendar," "Open notes," or "Open weather." These are particularly useful for quick information checks throughout the day.

App Recognition and Setup

Connection Requirements - Gemini connects to apps listed in your phone's Gemini Apps page settings. If an app isn't responding to voice commands, check that it's enabled in your phone's Gemini settings under the Apps section. The smartwatch inherits these permissions from your mobile device.

Success Tips

Voice Command Best Practices - Use clear pronunciation of app names, and if Gemini doesn't recognize an app name, try variations or the full official name. The feature works best with well-known apps and those properly integrated with Android's voice command system.
