FAQ

The Wesper app works on models iPhone 7 and up, and iOS versions 15 and up, and on the latest Android version.

Wesper can detect 4 sleep states - Wake, Light, Deep, and REM. Wesper uses your breathing, heart rate, and movement patterns to tell if you’re awake or asleep, as well as which sleep states you were in during the night.

Wesper's algorithms use breathing, heart rate and motion patterns to detect if you’re asleep. Total Sleep Time is a sum of all of the times throughout your session when you were asleep.

Sleep Efficiency is calculated using Total Sleep Time (adding up all the periods of sleep throughout your session) then dividing that time by the length of the whole session to produce a percentage.

Wesper can generate accurate insights about the quality of your breathing, amount of time snoring, sleeping positions, heart rate, sleep time, sleep efficiency, and sleep staging (wake / light / deep / REM). It also provides other environmental measurements, such as patch temperature and ambient noise.These insights are provided for each night test and as trends over time.

Wesper uses clinically-validated respiratory measurements to identify periods of inconsistent breathing throughout the night. If your breathing volume decreases frequently or lasts for long periods of time, you're more likely to have restless, lighter sleep, and experience increased daytime sleepiness, dizziness, headaches, and overall reduction in quality of life.



Wesper uses the microphone in your mobile device to record audio with your permission. The audio is then processed by Wesper’s algorithms to pick out periods of snoring. For best results, try to keep the mobile device as close to you as you can, for example on a nightstand or on the floor next to the bed.
