Kaia Personal Trainer uses patent-pending AI-powered motion tracking technology, without the need for additional hardware, transforming your iPhone into a virtual personal trainer and helping you achieve correct exercise execution.

• Get real-time audio feedback on your exercise performance.
• Automatically counts the number of correct repetitions.
• No cheating possible. ;)
• No equipment necessary.

• You are greeted by Kaia, the apps’ virtual personal trainer who guides you through the exercises.
• Place your iPhone upright on a table or against a wall, then step back approximately 7 feet until your body becomes visible on the phone’s screen.
• The app then tracks 16 key points on the body using the phone’s camera.
• This contrasts your observed pose with the ‘ideal’ predefined pose and compares metrics including the relative positions of limbs and joints, and the angles between them.
• During the exercise, Kaia offers actionable, real-time audio feedback and video instructions which encourage you to achieve the perfect exercise form - thereby offering the skills of a personal trainer at your fingertips in the comfort of your home.

Great but...

I have scoliosis, so it’s a little painful for me to do the motions sometimes. I’m trying to exercise more to help with my back pain. I would love if there were options or motions catered more towards people like me who find it difficult to do the squats. It’s really frustrating and maybe I just shouldn’t be doing squats, I don’t know 🤷🏾‍♀️. Overall though, this is a great app, but it’s not really for me.

Developer Response ,

Thanks a lot for your feedback. Kaia actually offers a second app "Back Pain Relief at Home", which is a medical grade app for managing back pain. Maybe that is also helpful for you? But nevertheless, also this app includes more exercises by now. We would love to hear if they are more suitable for you?

Great concept but doesn’t work

I really liked this app at first. It’s an absolutely wonderful idea! But the detection simply doesn’t work. Every single squat I do, it tells me my knees are past my toes or I’m overextending my neck. I’ve tried every position I can think of and I get the same response, so more than half my squats aren’t counted. I’ve had people watch me exercise who say my form is fine but the app still doesn’t count it. Maybe it’s user error and I would be happy to change my review if someone can tell me how to fix this problem! But otherwise, it’s getting too frustrating. Hopefully this can be solved!

Easy way to work practice form with feedback

Really easy way to get instant feedback on form. It would be nice if it included help and on how to improve bad form, but it is easy to research elsewhere.
