Insane. The absolute best workout app

I hope they keep it this way - you get daily workout programming. That is insane value. The programming is intelligent and has different levels: beginners, intermediate, advanced.

You are given a progressive workout program for FREE.

Maybe I'm missing something but if this keeps up the way it has been, I'm going to have to recommend this over a gym membership, personal training, and obviously over freeletics.

Well done on finding a way to give beginners and normal people a complete parhway to build up to the amazing gymnastics we all want to do!


The app works great I don't have issues with crashing myself, only issue I have myself is the music that is excluded from the app but on your channel but other than that I enjoy the freedom of the app!

Love the app but need help

I love the app but it won’t let me go into it now and keeps crashing on me. Please help!
