Most fitness apps make you dig through exercise databases or guess your calorie burn. Motion AI just listens; say what you did ('30 min of intense basketball') and AI instantly classifies the activity and calculates accurate calories burned, no manual searching. We're calorie-burn-first, not food logging: built to combat the rise of inactivity. Track your whole day, not just exercise ("Folded laundry for 30 mins"). And compete with your friends on who can burn more!
Hey Product Hunt!
I built Motion AI because I was sick of how hard it was to track calories burned without having an apple watch or something similar. Every app wants you to search databases and scroll through menus, and reducing that time was my goal.
There was also a bigger problem that I found deeper into my journey of making the app. I found research from multiple sources that say the world is becoming more sedentary due to the rise of desk jobs or unemployment. It's set to impact billions by 2030, and I thought I could be a small help to combat that issue! People aren't moving enough, or they go to the gym and then sit for the rest of the day. Wearables can be helpful, but they are so expensive. So I built Motion AI for a fraction of the cost with the same accuracy.
The core idea is simple: Why not just type or say what you did and get how many calories you burned?
The app uses a hybrid retrieval and LLM pipeline.It pulls a shortlist of the most likely matching activities from a MET value database, then lets the AI pick the best one and reason about intensity, duration, and your personal stats to get an accurate calorie estimate. It's a lot more reliable than a single black box AI guess, and way faster than pen and paper.
My approach evolved a lot along the way. I originally started building this as a food logging app, but realized the "calories in" space is incredibly crowded and mostly solved. The "calories out" side, actually understanding what you did physically and how many calories it burned, was the part nobody had made effortless or accessible. So I pivoted hard to focus exclusively on activity and movement, not diet.
Would love to hear what you think, especially if you've fought with clunky exercise logging or pricey wearables before.
Happy to answer any questions/concerns about the product!
Thanks!
