Zōn is for people who train more than one thing: lifting, running, Hyrox, conditioning. Film a set and it scores your form in about 3 seconds and tells you exactly what's off. It reads your HRV from Apple Health and moves each day's plan based on how recovered you are. And it shows the reasoning behind every change, so it's not a black box. Workout tracking, cardio, and nutrition in one app. iOS, free to start.
Hey Product Hunt 👋
I'm Tom. I've been lifting + doing cardio for about 5 years, and Zōn came out of a problem I couldn't fix with the apps I already had: Strava for the runs, Hevy for the lifts, MyFitnessPal for food and none of them knew the others existed, let alone how recovered I was. My Tuesday (Hyrox work) and my Thursday (heavy strength) are completely different days, but every app treated them the same and let my calendar decide instead of my body.
So I built the thing I wanted. Three parts:
- You film a set: squat, snatch, deadlift, push-up, KB swing, sled push, whatever and it scores your form in about 3 seconds and tells you what's actually off.
- It reads your HRV and recovery and moves that day's plan. Under-recovered, it pulls volume back. Fresh, it lets you push.
- For every change, it shows the reasoning, so you can see why volume dropped or an exercise got swapped. I didn't want a black box telling me what to do.
The moment it clicked for me was a little embarrassing. I filmed a bicep curl I was sure was clean. Zōn gave me 70/100: excessive momentum, elbows drifting forward, no control on the eccentric. I was annoyed, mostly because it was right. I spent two weeks fixing it and my weaker left arm finally started catching up. That's when I knew the form check was worth shipping.
Honest state of things: this is early. I'm fixing things as fast as I find them.
A few things I'd actually like your read on:
If you train hybrid - how do you stitch together strength + cardio + recovery today, and where does it break?
For the form check: which movements would you genuinely film mid-session, and which would feel like too much friction?
Does seeing the reasoning behind a plan change make you trust it more, or do you just want it to tell you what to do?
Tear it apart - that's more useful to me right now than a kind word. I'll be here all day.
