Very motivating

I came across the video on reddit. Interesting to see where this went with the content and competition beyond just tracking. The tracking actually worked really well for me. The best part in my opinion is the motivation you get both from the competition aspect, and also the fact that it’s “watching” you and nudging you to do better. I’d love to have a way to compete with my friends!

Love the form feedback!

I’ve been looking for something that helps me understand my form. I’ve been recording a lot of my workouts and sending them to a trainer friend to get feedback, so it’s pretty amazing to get it in real time! Also I like that it shows you the video example before you start each exercise so you have some time to remember how to do it.

What a fantastic app

Found out this app on ProductHunt on the launch day. Installed it just to see how it works, tried few workouts and then stopped using it. Missed the gym today and thought of giving it a try and I completely fell in love with it. Had a kickass workout. Thank you to the entire team for developing such an amazing product. 💪
