I have been using Muscle wiki for about a year as my primary fitness app. It has been pretty solid, but there is a major problem that gives it a 3/5 for me. The servers are awful and are run on toasters. I have 2 different accounts and am signed out every 4 months or so and am unable to sign back in again, then I am forced to alternate accounts. If the servers get fixed it would be like a 4/5 or a 5/5. Also some cardio exercises are missing like stairs

I consistently have to rebuild my workouts. I paid for the app, honestly took me a while to get motivated to start working out. Not upset about losing the money. But, at least three times I have had to rebuild the work outs. The mobile app is not very good. I can't get out of the tutorial part for the exercise without backing to the user name and password. Lame and a waste of time.

The app randomly changed my Unit Preferences from lbs to kg. I changed it back and then in the middle of a workout it changed half of my exercise back to kg weight. Also the audio alert after the timer ends lowers the volume but doesn't raise it so I end up having the volume on my phone turned up to the max by the end of the workout just to hear my music.
