A short guide for your first weeks. If anything is unclear, the Support page and info@tritune.co are the places to ask.

1. Add it to your Home Screen

Open the link we sent you in your phone's browser, sign in, then add the app to your Home Screen and open it from the icon. On an iPhone, tap Share, then Add to Home Screen. On Android, open the browser menu and choose Install app or Add to Home screen.

Do this first. On an iPhone, session reminders only reach you from the Home Screen icon, and the icon opens the app full screen without the browser bar.

2. Choose your data source

TriTune reads your sleep, heart-rate variability (HRV) and resting heart rate, plus your workouts, from the watch or ring you already wear.

  • Oura or Google Health Connect: Profile, then Connections, then connect it yourself.
  • Garmin or Zwift:TriTune doesn't connect to Garmin directly. Triathlete accounts can link through intervals.icu, a free training site that Garmin and Zwift can send your data to. Connect Garmin there, then look for it under Profile, then Connections, which shows every source open to you.
  • Apple Health: isn't open to testers yet.
  • No watch or ring: wellness accounts can start with daily check-ins alone. Triathlete accounts can open their plan and check in each day, but the plan only adapts to your recovery once a watch or app is connected.

3. Your first two weeks

TriTune learns what normal looks like for you, so the first days are quieter than the later ones.

  • About 14 days of HRV readings to build your own baseline. Until you have them, the app tells you your HRV history is limited rather than pretending to know your normal.
  • About 42 days for the fitness picture on the triathlete side. Fitness is a 42-day average of your training, so it keeps settling for about six weeks after your first synced workout.
  • Wear your watch or ring to sleep, and check in each day. A few gaps are fine. The app says when it is working from less than it would like.

4. If something looks wrong

Open More, then Report a problem. It sends us the screen you were on and a private tester code, not your email or name. If you'd like a reply, email info@tritune.co instead.

5. Export or delete your data

Profile, then Your data. Download everything as JSON, or your activities as CSV, any time. To remove your account, use Delete my account on the same screen. See the Privacy Policy for what we hold and why.
