How to Open Apps with Gemini Voice Commands

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

Gemini launches any app installed on your watch through simple voice commands. This eliminates scrolling through app lists on a small screen, especially useful during workouts or when your hands are occupied.

Basic App Launch Commands

Open apps by saying their name with a simple command prefix.

Standard Format: Say Open Spotify, Open Gmail, or Open Timer to launch apps directly.
Alternative Phrases: Launch Settings, Start Strava, and Open up Calculator all work to launch apps.
Common Names: Gemini recognizes common names, so Open email works for Gmail and Open music works for your default music app.
Watch vs Phone: Commands open apps on your watch by default. Say Open Spotify on my phone to launch on your phone instead.

App Name Recognition

If Gemini doesn't recognize an app, try the full official name from the Play Store listing. Open Runkeeper works better than Open run tracker.

Fitness and Health Apps

Launch workout and health apps hands-free when exercise makes touch difficult.

Workout Trackers: Say Open Strava, Open Nike Run Club, or Open Samsung Health to start fitness tracking.
Quick Start: Say Open Fitbit and start a run to launch and begin tracking in one command.
Health Checks: Say Open Google Fit or Open heart rate to access health monitoring apps.

Media and Entertainment

Access music, podcasts, and media apps without touching your watch.

Music Apps: Say Open Spotify, Open YouTube Music, or Open Pandora to access your music library.
Podcasts: Say Open Google Podcasts, Open Pocket Casts, or Open my podcast app.
Combined Actions: Say Open Spotify and play my workout playlist to launch and start playing immediately.

Productivity Apps

Access utilities and productivity tools quickly.

Calendar: Say Open Calendar or Open my schedule to view upcoming events.
Notes: Say Open Keep, Open notes, or Open Google Keep for note-taking.
Utilities: Say Open Calculator, Open Stopwatch, Open Weather, or Open Maps for quick access to tools.

Troubleshooting App Launch

What to do when voice commands don't open apps.

Check Installation: Ensure the app is installed on your watch, not just your phone. Some apps are phone-only.
Use Official Name: Try the exact app name as it appears in the Play Store. Nicknames don't always work.
Check Permissions: On your phone, open Gemini Extensions Connected apps to verify the app is enabled.
Restart Watch: If commands suddenly stop working, restart your watch to refresh the connection.

Voice Launch Strategy

Create shortcuts by combining app launches with actions: Open Timer and set 5 minutes is faster than opening the app then setting the timer manually.
