Nah, I'm a Google play store maxi now;)
Have you ever used obtainium on Android? If not give it a try for your apps.
Obtainium can scrape github projects for APK file releases and install them for you.
Go to the releases page and download the APK file from the latest release. https://github.com/JunkFood02/Seal/releases/tag/v1.12.1
