Help make ZonePit better

ZonePit is a training and recovery coach that runs entirely on your iPhone. Before the App Store launch I am looking for 30 to 50 people to try it in everyday use and honestly tell me what is missing: on the bike, on the run, in the water or simply for more movement and better sleep.

Join the beta on TestFlight

How to join

1. Install TestFlight (free on the App Store), open the beta link and download ZonePit.
2. Open the app and allow Apple Health. If you have few workouts in Health yet, use “View with sample data”.
3. Try it for a few minutes (suggestions below) and tell me how it went.

What you need

• iPhone with iOS 27 or later
• Workouts in Apple Health, whether cycling, running, swimming or strength (e.g. from Apple Watch, Wahoo or Zwift)
• For readiness and sleep: a watch that writes HRV, resting heart rate and sleep to Apple Health
• Optional: Apple Intelligence for the AI coach, a power meter for cycling, an Intervals.icu account for the Zwift route

What you can try (about 15 minutes)

• Workouts: Are your sessions there, and are heart rate, pace or power right?
• Today: Do readiness and sleep score match how you feel? Is the explanation clear?
• History: Do fitness, fatigue and form fit? Are best efforts and threshold suggestions (FTP, threshold pace) right?
• Plan: Create a week. Is the explanation clear, does the load fit across your sports?
• Coach: Ask two questions about your training. Are the answers helpful and traceable?
• Optional: Send a session to your Apple Watch, or to Zwift via Intervals.icu.

How to give feedback

• In TestFlight: take a screenshot and tap “Send Beta Feedback”. This also works after a crash.
• By email: briefly describe what you did, what you expected and what happened.
• Please check screenshots before sending: they can show your training data.

Your data

Even in the beta your health data stays on your iPhone. I do not receive it. Only what you deliberately send me as feedback reaches me.
