You’re right there, doesn’t seem the Android app is OSS. Though, their Android TV app is open-source, same thing for their home assistant.
That’s weird. I’ve re-requested an Exodus review for the new version (2.11) and still the same. Maybe I should check that out with the team.
On a positive note though, they are a non-profit organization (a.k.a. You should donate to them if you like what they do). They are not a Muslim Pro [1] [2] app (which is just awful in terms of privacy). For me, it’s just the best balance between privacy, accuracy, usability and feature set. This app is better than over 99% of all Play Store apps.
