A group of open source Android apps without ads or unnecessary permissions
I am a heavy user of f-droid and avoid these 'Simple' apps.  The high level of nag is not just annoying but borders on begging.  Having pro versions where you can change colors defeats the idea of open source.  I hate bringing the negative energy, but there is a treasure of apps available with f-droid other than these.  I am glad they have their own website and wish they just went and did their own thing there.
