Best Ive Tried
After extensive attempts to use Strong (Confusing), and Fitlist (Even the paid version was buggy and would lose workouts halfway through), I finally found Gymaholic. I bought the Pro version of the last release. Every app has to balance ease of use with functionality, and theyve found an excellent middle ground between too confusing to use and too simple to do anything. The only flaw I found was if the watch app wasnt responding and you accidentally tapped the screen again, you could lose your workout. They have corrected this in the latest release; it gives you the option of continuing an interrupted workout. Very happy with this app.
