iHealth Air Pulse Oximeter review

The iHealth Air is the best value if you want your readings on a phone. For $39.99 on sale it pairs over Bluetooth with the free iHealth MyVitals app, which records several users and charts SpO2 and pulse trends by hour, day, week and year. The app also shows a live plethysmograph and perfusion index, which iHealth says help confirm that a reading is stable. Unlike every battery-powered clip on this list, the Air has a built-in rechargeable battery that takes about 3 hours to charge and lasts up to 300 uses. iHealth lists an SpO2 measuring range of 70 to 99% with plus or minus 2% accuracy and a pulse range of 30 to 250 bpm. It is a spot-check device, so iHealth advises using it before or after exercise while still, and it does not log overnight like the Wellue O2Ring.
