I love this app but it is missing something? The android version of this app is much better! Wish it felt like the android version!!!

The simplicity is the best thing about the app. The only critical feature missing is that when you save your reps, i wish you could click on a saved entry so that it gets loaded to the main screen. Why? I use this for several exercises. I have each of my reps saved. Every time I use it I need to recreate the reps rather than just work off my saved entries.

Updated all my apps and software on iPhone and this app is no longer working. Hundreds of data points that I cannot access. Would give 5 stars if this was fixed. About 2 weeks in waiting for response from App Store support.
