Overall pretty smooth and flexible workout tracking app, but with numerous rough edges. I'd expect better from a somewhat expensive app that is several years old. THE GOOD: - You get nice muscle graphs per routine, and one for total muscle fatigue at this moment. - Nice workout log. - Tracking workouts is pretty good. Just push a button to record a set or start the rest timer. Could be more automated, like automatically starting the rest timer after recording a set. - Pretty smooth workout tracking overall. Nice amount of flexibility. Can leave the workout sheet without losing progress (except for rest time). You can see whether you reached the target number of sets and reps for each exercise. - Visually appealing. COULD BE BETTER: - Counting up the time since last workout is very nice, but doing so by the second adds an annoying flicker to the home screen. - There is a large exercise lilbrary. Would be nice to have an illustration for each, so I don't have to sit there with Google on my computer to figure out what they are. - If you have trouble finding an exercise in the library, you can't add custom exercises. (Confusingly, bodyweight exercises are called "Your custom exercises", but there's no customization available.) THE BAD: - Finding the right exercise is too hard: when you search, the results have to match the exact substring. Would be better if it showed matches with all words irrespective of order ("n-gram" type indexing, which is pretty standard in the software industry since a couple of decades). - When adding exercises, accidentally swiping or tapping back loses progress. Would like a warning like "Are you sure you don't want to add these 13 exercises?" When you choosing reps/sets, you scroll each digit individually. This is quite awkward and finicky, especially considering that there is no smooth scroll animation, just flickering numbers. Entering weights is especially annoying (jerky scroll to "1" and then "5"). The standard iOS control lets you either type quickly or scroll smoothly.) - Very limited free trial. Only 3 workouts before paying up! Seems ridiculously stingy these days, when free trials of two weeks to two months is common. Also, there is no monthly plan, only a yearly one, meaning you have to splurge quite a bit to even try it properly. FEATURE REQUESTS: - Would be nice to track single-leg exercises specifically for each leg. If I want three sets of 10 for each leg, currently I have to put six sets of 10 or three sets
