the new update is WAY too intrusive. All of the features themselves are great additions, but the data I input should be prioritized (what my last workout weights were, and what weights I have now). The recommended weight increases are in the way, and often suggest weights that aren't practical (e.g. 41.3lbs for a dumbbell weight) making this feature useless anyway. the UI needs some heavy cleanup.

We are working on cleanup now. It should in fact show you last workout weights vs suggested. Apologies here. We are also going to add a "turn off suggestions" option to completely hide it. You mentioned the "The recommended weight increases are in the way" would you mind sending us a screenshot? support@muscleiwki.com

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*

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.
