Body position can be important to sleeping well, especially if you snore, or if some positions tend to give you back or neck pain. The SomnoPose sleep position monitor can help you manage your sleep position.

SomnoPose is designed to run all night, while you wear your iPhone or iPod touch. It continually monitors the device's orientation, and provides an all-night chart of sleep position, along with a summary that shows how much time you've spent in each general position. An optional alarm can be used to help avoid undesired positions.

- Continually monitors accelerometer data to determine your body position.
- Shows how much time you've spent facing left, right, up and down.
- Provides charts showing position data for entire nights.
- An alarm can alert you when you're in a position you've chosen to avoid.
- Shows built-in help content.

- Does not transfer information from your device unless you explicitly export data. You control where your data goes.
- Does not need a network connection (except if and when you export data)
- Does not have in-app advertising, in-app purchases, or subscription fees.

- Scrolling chart on the main screen shows real-time position data.
- Screens have dark backgrounds, suitable for use in low-light conditions.
- Alarm volume can increase gradually to avoid jarring users (or partners).
- Audio from another app can be played in the background.

- Alarms and statistics are automatically paused while you sit up or stand up.
- The angles for determining body positions are adjustable.
- Chart images can be saved as photos, printed, sent to other apps, or exported.
- Collected position data can be exported via email, messages, or other apps (as a CSV attachment).
- Controls can be "shielded" to prevent accidental changes.
- Uses the iPhone proximity sensor to shut off the screen during the night, saving battery power.


* To use SomnoPose to monitor your sleep position, you will need to wear your iPhone or iPod touch in a stable, forward-facing position while you sleep. The internal help and the SomnoPose website help pages describe several ways of wearing your device.
* SomnoPose is not intended to diagnose or treat any disease. Its purpose is to monitor and record information about body position.

Ratings and Reviews


Really great

Apnea is worst when sleeping on your back.
This app trained me in only a few nights to sleep on my side. My CPAP sleep score became 99 out of 100 as a result.

Really great idea. Position monitoring devices cost about $400. This app does the job.

Must leave somnopose as top program. Don't lock the iPhone. (don’t push side button when operating the app). And cover the proximity sensor (barely visible round dot next to iPhone receiver).

The app allowed was export now so I’m able to compare positions with Apnea data.

Very good.

Great for avoiding sleeping on your back if you have apnea.


Easy to use, provides great information

RePose was a great way for me to get basic information on sleep position, as I am someone who suffers from periodic neck pain. This app is easy to use, there's great information within the app and on the Proximal Box website to get you started. I was definitely a bit skeptical of the ease and comfort of wearing my ipod touch, but it was far simpler than expected. As long as you aren't a stomach sleeper, wearing your ipod or iphone should be pretty easy. The ipod fit in my money belt perfectly. I put it on, got the ipod set up with RePose, and went to sleep. In the morning I had a really nice little graph showing how I changed position during the night, and a summary of total time on each side and on my back. I did not use the alert feature since I really just wanted the information, so cannot comment on that, though the gradual increase in alarm volume seems like a great feature to help people change their sleep behavior. Definitely recommended for anyone with sleep problems, or for people who are just curious about how they sleep.
