Target SDK Patcher for Watch Face AABs
Waiting for Samsung Watch Face Studio to add support could take a while, and even then, you'd still have to repackage every watch face one by one. This tool does it in a couple of clicks, for as many files as you need. It's free. If it saves you some time, a donation would mean a lot, just a way to say thanks.

AAB targetSdk / version patcher

Everything runs locally in this browser tab. Your .aab files and keystore are never sent anywhere — not to a server, not anywhere else.

1. AAB files

Drag .aab files here, or click to choose
No files added yet.

2. Target SDK

3. Signing (keystore)

Select the path to your key — the exact same one you used to originally sign this app.
Passwords and keystore contents are processed only in this tab's memory and are never transmitted anywhere.

4. Patch & sign

We recommend verifying the output with jarsigner -verify -verbose file.aab before uploading to Google Play Console. This tool is provided "as is", with no warranty of any kind — you are solely responsible for testing and verifying the result before publishing to production.

Thanks for using the tool, hope it saved you a few hours of waiting around and manual repackaging. If it did, and you'd like to say thanks, a small donation goes a long way.
