Get pulse and blood oxygenation readings using only your phone! Simply hold your finger against the phone camera and flashlight and press SCAN.
This amazing technology uses small color variations in your finger to determine your pulse BPM and the blood oxygenation. Scans take about 7 seconds; you can take multiple readings for more accurate results.
For use by those with asthma, sleep apnea, or other conditions requiring one to monitor SpO2 levels, such as acclimating for high altitude hiking.
