    Best gym app for WP out there. Only complaints are the lack of superset scheduling and lack of interval timers. UI is nice and easy. Great selection and organizing of exercises

    I've been using this app for about a year and its still the best. I tried to find something similar on ios for my wife and there isn't anything as simple, easy to use, and as clean as this. Thank you!

    I tried pretty much every gym app I could find and this one seems like the best. Works the way it is supposed to and looks better than any other gym app.

    Have used this app for only two weeks but loving its functionality. Looking forward to seeing how the prediction model works going forward. Will update as I go.

    I do like the app but I would like to see improvements. I would like to be able to track my supplement intake.
