Decent, but needs lots of work.

Being able to look up exercises by primary and secondary muscles is the best thing about this app. Besides that, it has little else to offer.

The workout feature is cubersome to use. Creating workouts is messy; all the workouts are listed in a single list without a way to filter them by muscle group. Also the naming of muscles is not what most people are familiar with.

Some excercises have duplicate names, only after you click on them do you find out that one is performed with dumbbells and the other with a barbell, for example.

The worst usability complaint for me was entering weights or rep counts for exercises. The menus that appear are too short and move by large amounts fom even the smallest scroll, making it hard to enter values. Ideally, in the desktop version at least, these would be normal entry fields so users can easily input any number.

A nice featrure to have would be the ability to filter excercises by equipment, for example to only show dumbbell or cable exercises.

Overall, not too bad. If you dont know what excercies you can use to train which muscles, this is a good tool for you. But if you want to track your workouts, dont bother. At least not this version (1.0). After using the workout feature once, went back to my trusty spreadsheet.
