I bought the 6-month Premium plan, but requested a refund the same day after trying the app. The workouts felt unrealistic, too many exercises in too little time, constantly moving across the gym, and no clear structure. Even the custom workout generated random movements instead of a balanced plan. I wouldn't recommend paying for a long-term subscription. Try one month first to see if it fits your needs.

I selected what equipment I had and the only exercises it gives are with the one thing I don't have. Their response took me reaching out for a week just to have them tell me to do the apps job for it. before spending money be aware they do not take responsibility for their issues and they do not do refunds. Even if you email them with an issue the day you pay. DO NOT WASTE YOUR TIME.

Not satisfied at all. You have to pay to explore the app and features and by then I realized that I am not interested in building my own workout routine and paying for every added feature. within 24 hours I've requested a refund, but have to wait another 12 hours for a response. I am currently on my third round of emails requesting a cancellation and refund. I continue to get a run-around response instead of a direct confirmation to my request. I would NOT get this app!
