I looked into this before, but I found the options were too stripped down.
Ultimately I need:
Maps
Music streaming
Web browser
Email
Wallet functionality
Then there are miscellaneous apps that I need as well, some that don’t have browser functionality (local bike rental app) or something like a workout tracker.
Thing is, if you start adding functionality for the above then it’s just a regular smart phone and there’s nothing stopping you using the apps you’re trying to avoid :/
