Phenomenal value, as it has nutrition tracking and coaching, plus like weight lifting tracking and recommended adjustments. The Facebook community is outstanding. Great for losing weight or building muscle - you can set it up for anything in between as well. Has video guidance for every exercise, a rest timer, and tells when you when to go up or down in weights or reps. Is based on well proven science, not fads that fade. I've been working out for close to 30 years, and this app does it all

Too buggy. Half the time I couldn't even log in. password reset wouldn't let me change my password. And the few times I was able to login, the set up process got stuck on a loading screen. Tried on several devices, no luck. Shame, I was looking forward to trying the program. Edit: I tried restarting. Didn't help. I tried reaching out to support. They ignored my email for several days.

I love built with science app. I haven't been able to see it's full potential, due to my own lack of consistency. but in whole, the app is great as far as tracking everything, from weight, workouts to meals. it also motivates you to do better and stay consistent. I just haven't found my niche yet, but hopefully soon I will!
