Track your blood oxygen in Gyroscope

Wear your watch or ring to bed, and Gyroscope shows last night's blood oxygen beside your sleep every morning.

How to track it

Wear your Apple Watch (Series 6 or later), Oura, WHOOP 4.0 or Garmin with Pulse Ox on to bed. Gyroscope takes your blood oxygen over the exact sleep window, drops the awake samples near waking, and shows it each morning with your Sleep Score, with the drinks you log beside your sleep. Nights with an average under about 94 or a lowest value under 90 are the ones to look at.

What Gyroscope One adds

• The rest of your night. Gyroscope One adds your breathing rate, wrist temperature and how far your heart rate dipped.
• A record of your nights. Your nights stay in Gyroscope One as a trend, so a run of low ones is easy to show your doctor.
• Drinks beside your sleep. Log your drinks in Gyroscope One and the nights after drinking sit next to the rest, so a low night can be checked against what you drank.

Gyroscope gives lifestyle suggestions, never medical advice, and it doesn't diagnose anything from your oxygen.
