Track your breathing in Gyroscope

Do your sessions in any app that saves mindful minutes to Apple Health, or with the timer in Gyroscope, and Gyroscope One puts them next to your overnight HRV, resting heart rate, breathing rate and mood. After a month you can see if it's working for you.

It's the same test the guide uses, your mood before and after and the nights that follow, kept in one place.

What else comes with Gyroscope One

• The breath hold benchmark. Gyroscope One has the breath hold as a one-minute test, scored against your peers, so you can retest every month or two and watch your breath score move. The breath hold benchmark.
• Custom Meditations. Your coach in Gyroscope One can also write you a meditation, from 2 to 30 minutes, for the week you're having. Meditation in Gyroscope.

How your sessions get there

• Any app that saves mindful minutes to Apple Health, including the Mindfulness app on an Apple Watch.
• The timer in Gyroscope, on your iPhone or your Apple Watch.
• Your nights come from your Apple Watch, Oura, WHOOP or Garmin.

The timer on this site doesn't save your sessions anywhere, so for a record, use one of those. Gyroscope is an iPhone app.

What to look at after a month

• Your mood before and after. The best test you have, and it improved in both month-long trials.
• Your breathing rate at night. In the Stanford trial it fell more with breathing practice than with meditation. Compare it with your own usual weeks.
• Your HRV. It jumps during a session, but a month of practice didn't move resting HRV in two trials. What to watch on your ring or watch explains why.
