To install Horizound while the app is in the testing phase, there are two mandatory steps. Without completing both, the Play Store will not allow the download.
1. Join the testers group
First, you must join the official tester group on Google Groups.
👉 https://groups.google.com/g/horizound-testers
This step is essential: it authorizes your Google account to access the test versions.
2. Activate tester access in the Play Store
After joining Google Groups, you need to activate the testing program in the Play Store itself.
👉 https://play.google.com/apps/testing/com.solmaxys.horizound
Once you load this page and confirm that you want to be a tester, the Play Store will allow you to install Horizound and receive future updates automatically.
Why this process?
This ensures that only registered users and volunteers have access to the development version. It allows us to better organize feedback, control releases, and prevent accidental downloads of unstable versions.
