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.

Since the last update, my workout weights have all been weird when I go on, I have to reset the weights for each set. If I have bicep curls at 25lb it goes to 55.x lbs, and does this for every set of every exercise. When I fix it all, I make sure to save and update template but when I go back in the next time the weights are all jacked up again. Let's get that fixed and I'll update my stats again bc this is a great app. i wish it had a simple calendar that let you schedule workout plan. *fixed*
