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 chose to pay for this app so I can keep track of prior workout weight and reps. The app keeps deleting old workouts and deleting the previous history for comparison. It also won't let me delete a "set" if I accidentally add an extra one. I would have to delete the whole exercise and lose any history (if the app didn't do that already)

You've done a really amazing job with all the exercise videos and they've been very helpful for me. Unfortunately, I find the tracking features quite basic. I would like to have exercise thumbnails on the tracking screen and the option to expand/collapse all sets of an exercise to save space on the tracking screen. But what I miss the most - being able to log a past wrkt, edit a past wrkt & change it's duration. These are the things preventing me from using this app for exercise tracking.
