Find 12 Testers for WearOS Apps & Watch Faces
Pass Google Play closed testing with phone-only testers. No smartwatch owners needed.
The Problem
Google requires 12 testers with smartwatches for a 14-day testing period. Finding Galaxy Watch or Wear OS device owners willing to test your watch face is nearly impossible.
The Solution
Create a companion phone app with the same package name. Mobile testers count toward your watch face's testing requirements.

Same package name
Links to your watch face
Same keystore
Proves same developer
Shared testing track
Mobile testers unlock watch face
Prerequisites
Before you begin, make sure you have:
- Your keystore file - The same
.jksfile you used to sign your watch face or WearOS app - Keystore credentials - Password, key alias, and key password
Critical: Use the same keystore
The companion app must be signed with the exact same keystore you used for your watch face or WearOS app. Using a different keystore will result in a signature mismatch and Google Play will reject the upload.
Generate the Companion App
Use our free Companion App Generator to create a phone app that matches your watch face or WearOS app. The tool builds a simple companion app that displays your watch face preview and includes basic settings.
Enter your app name - Use the same name as your watch face for consistency
Enter your package name - This must exactly match your watch face's package name
Upload a preview image - A screenshot or preview of your watch face (400×400px recommended)
Fill optional fields - Privacy policy URL, support email, and version details
Click Generate - Wait 5-7 minutes while the app is built
Download files - Get the AAB file (for Play Store) and optionally the APK (for testing)
Package name must match exactly
Double-check your watch face's package name before generating. Even a small typo will prevent the apps from being linked on Google Play.
Sign the AAB File
The AAB file you downloaded is unsigned. Before uploading to Google Play, you need to sign it with your keystore. The easiest way is to use our free online signing tool.
Free Online AAB Signer
Upload your AAB and keystore, enter your credentials, and download the signed file. Your files are processed securely and deleted immediately after signing.
Security & Privacy
The signing tool is open source and processes files server-side using the official Java jarsigner. Your keystore and credentials are never stored - files are deleted immediately after signing.
Alternative: If you prefer not to use this tool, you can sign locally. Just ask any AI model: "I have an unsigned AAB file and a keystore file. Guide me step by step on how to sign the AAB using my keystore."
Upload to Google Play Console
With your signed AAB ready, head to the Google Play Console to upload your companion app.
Create a new app in Google Play Console (or use your existing watch face listing)
Go to Closed Testing and create a new track
Upload the signed AAB Google will verify the signature matches your app
Complete the store listing Add description, screenshots, content rating, and data safety form
Add testers and start testing Invite 12+ testers to join your closed testing track

After 14 days of successful testing
Once your companion app passes the 14-day closed testing requirement with 12+ testers, you can promote your watch face directly to production. The testing requirement is shared across both form factors!
🎉 That's it! You've completed all the steps.
Now you just need 12 testers to join your closed testing track and actively test your app for 14 days. Once that's done, your watch face will be eligible for production release on Google Play.
