Apparently the recent lack of updates on F-Droid is due to them including referral links for hotels and refusing to remove it or make it an opt-out feature...
//edit
Looking at the discussions it's even worse, the devs try to argue that F-Droid is being unfair and referral links shouldn't be "misclassified" as ads...
I tried using Magic Earth and especially the driving mode is great and sometimes it worked flawlessly but I regularly had freezes and crashes. Do you have any issues with it?
