Issue description:
I have a locked down Android phone I though I’d use a focus music player, IE no distracting apps. I wanted to use Symfonium (which I have payed for), but my only options for installing apps are APKs (due to the locked down nature of the phone). There doesn’t seem to be anywhere to get a Symfonium APK due to its sole release on the Play Store. Are there any possible workarounds? I have tried looking on sites such as Bullet and Mirror but they provide weird proprietary apk formats that will not do.
