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'd like to give this app a higher review, especially because I can see the team actively working on the app and improving it. The number one reason I can't give this more stars yet is because every time changes are pushed to the app, it resets lots of data that I've put into it so far. Weights, sets and reps mainly. The other thing it messes with is the rest timer and notifications for it. I often have to go to settings to turn off and back on the auto rest timers and push notifications.

We understand how annoying that must be. We're working on a solution. We hope you'll re-consider the rating once we fix the issue.

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.
