When I first started ttc I tried to use FertilityFriend and it was terrifying. I couldn't figure anything out, or how to navigate it, so I just deleted it and stuck with glow. But today just to see if it had gotten any better I downloaded it, and after a year of this, I now can navigate it like a pro, lol! It tracks so much more then the other apps I've tried, so I'm pretty excited about not having to use three apps to track everything I need to!
