How ZON works
One app for your whole training week
Train, recover and adapt without juggling a gym logger, a running app and a spreadsheet.
Every session, one log
Strength sets with RPE and a rest timer, GPS runs with live pace, Hyrox circuits with stations. The workout player switches mode for you.

Know when to push
Each morning, sleep, HRV, soreness and training load become one readiness score, with a clear call: push, hold or recover.

A coach that adjusts
When your load or recovery shifts, ZON rebuilds the next session instead of repeating the plan, and explains why.

Apple Watch, Health and offline
Log from your wrist, sync sleep and HRV from Apple Health, and train with no signal. Everything syncs later.
Nutrition that follows training
Snap a meal for its macros, with targets that move with your training days.
“Honestly I was just using my Apple notes to track my strength training for years because every other fitness app felt like too much work. Tried Zōn on a whim and I'm hooked. It's so much easier to log my weights and check my past reps without scrolling for days. The workout tracker interface is clean, and I really dig that it ties in nutrition too. 10/10 would recommend if you actually want to see progress.”
FAQ
Questions before you download
Is ZON free?
Yes. ZON is free to download and to log your training. ZON Pro adds AI-generated programs, predictive analytics, AI form analysis, automatic post-workout analysis and your full training history. It is billed by the App Store and you can cancel anytime in your Apple settings.
Does ZON work for Hyrox training?
Yes. You can log runs and all eight Hyrox stations in the same session, build full simulations, and follow your splits and training load across the season.
How is ZON different from a gym logger like Hevy or Strong?
ZON logs strength and running in the same place, then uses your recovery data to adapt what comes next. Logging a set stays as fast as in a classic gym app.
Is ZON available on Android?
ZON is live on the App Store for iPhone. The Android app is in beta: join the waitlist and we will send you access.
Does it work with Apple Watch and Apple Health?
Yes. You can log from Apple Watch, and ZON syncs sleep, HRV, energy and workouts with Apple Health to compute your readiness.
Can I bring my current program?
Yes. Take a photo or upload a PDF or screenshot of your program and ZON rebuilds it as a structured plan you can train from.
Where is my data stored?
Your data is hosted in Europe, and you can delete your account at any time from the app settings.
