Fully agree on that. Always better to start fully fresh, even without such problems.
That said, it's still important that it will ship pre-installed. That way app-developers who block GrapheneOS cannot excuse their actions anymore by saying that it was your decision to use another OS, and therefore not their problem.
Wait, just two weeks ago I was looking for a new GPS logging app and didn't notice that there's now an official (and non-official) dedicated Android app available. I'll have to try it out.
I've been using Dawarich for a while now and the biggest problem was always finding a way to get a good app that can do both accurate, and battery-saving tracking.
Anyway, love the project and seeing it continually improving.
