If you still can’t find the app, the most likely reason is an incompatible Android or iOS version. In this case, please try a different mobile device (phone or tablet), if one is available in the household.
It is also possible that your Date of Birth was entered incorrectly in the SleepImage System. Please contact your healthcare service provider to verify your sign-in information.
If you paired a SleepImage Recorder in Bluetooth settings on the phone settings, unpair it first. Then, try the pairing process in the SleepImage App again.
Make sure Bluetooth is enabled, and that you have granted the necessary permissions to the SleepImage App. On iOS, go to Settings->SleepImage and enable the Bluetooth permission. On Android, go to
Settings->Apps->Permissions->Location and select “Allow while using the app”. Android phones will also need to have Location turned on under Settings->Location.
Make sure your phone/tablets’ operating system is up-to-date.
After pressing the button with the magnifying glass icon, with the recorder powered on, wait at least 60 seconds. Some phones take longer to discover and pair with bluetooth accessories.
Restart both the phone/tablet and the recorder.
If there is another phone/tablet available, try that one to rule out that there is an issue with the recorder.


- Take off the ring,
- If a countdown starts, wait until it finishes,
- Put the ring back on the finger and wait at least 20 seconds.
- SpO2 and pulse rate values should appear if successful.


Bluetooth Low Energy (BLE) is a low power technology, operating in frequencies between 2.4 GHz and 2.483 GHz ISM. It is very similar to WiFi, as it allows nearby devices to connect with each other.
Other devices such as other Bluetooth devices, WiFi, and even microwave ovens and fluorescent lights may interfere with the Bluetooth connection, as well as physical obstruction.
To minimize the chance of interference, it is important to make sure all devices that are being used are up to date as manufacturers may release updates which improve connectivity and make devices more robust to interference. This includes mobile device updates.
In addition, turning off non-essential devices and connections can help in reducing interference. In clinical practice, some patients may be using essential devices that cannot be turned off and they should consult a physician when making decisions on whether the device can be shut down while recording a sleep study.
In cases where an essential device, such as an insulin monitor, cannot be turned off, an alternative which may help is to use a different mobile device for recording the sleep study, if one is available in the household.
- Force-close the SleepImage App (see instructions for iOS and Android)
- Make sure the phone is connected to the internet.
- Open the SleepImage App.
- Wait and look out for notifications at the bottom of the screen indicating an upload attempt.
- Go to the History tab and wait until all entries in the list show “Upload Status: Completed”
- If you see error messages, try switching from Wifi to Cellular or vice-versa.
Switching from WiFi to cellular, or vice-versa, may also solve the issue.
The ‘Recorder Not Registered’ error message will appear when a study file attempts to upload from the SleepImage Mobile App, but the recorder used to collect data is not recognized. This can happen if there is a typo in the recorder’s registration or if the recorder is unauthorized.
If you are seeing this error message, please contact support@sleepimage.com with the recorder’s serial number (SN) and we will confirm the registration of your recorder. The serial number of the recorder will always be displayed in the ‘Settings’ tab of the SleepImage app while the recorder is paired.
While waiting for your recorder to be registered, please do not uninstall the SleepImage app or the recorded study files will be permanently deleted and the data lost. Unregistered recorders will prevent study files from uploading, so until the recorder is registered the only copy of your recorded study will be saved on the SleepImage app on your phone.
If you are scheduled to perform multiple nights of study, please continue to perform those studies even if the recorder is not registered, as the study files can be uploaded at a later date once the recorder is registered. You may also want to reach out to your provider to let them know of the registration issue, as no reports can be generated before the recorder is registered.
Once the recorder has been registered, you can retry uploading study files from the the SleepImage app by leaving it open for a few minutes, or by force-closing and restarting the SleepImage app. The ‘History’ tab of the app will display ‘Upload Status: Completed’ for each study that has been uploaded. Once all studies have been uploaded, the app can be uninstalled without the loss of study data.
If you continue to have trouble uploading your study files, please refer to the ‘Troubleshooting – Upload’ section above on this page.
If you have experienced a failed recording, consider using a different mobile device if available. Please review the “Upload” section above for instructions on how to ensure all recordings are uploaded.
When starting a recording, the app will notify you if new firmware is available for your SleepImage Ring. Firmware upgrades are mandatory to ensure that you get the latest features and best functionality.
During the firmware upgrade, please make sure to stay within range and keep the SleepImage App in the foreground on your mobile device.
Do not use your phone for other tasks while the upgrade is in progress.
If you encounter issues where the upgrade is failing, do NOT unpair your recorder.
If the upgrade fails, simply go back to the Recording page and click the start button. The app will notify you that the Ring is in range and the upgrade needs to be completed.
Once the upgrade is completed, your recording will start automatically.

FAQ
The app needs this permission because a Bluetooth scan can be used to gather information about the location of the user. This information may come from the user’s own devices, as well as Bluetooth beacons in use at locations such as shops and transit facilities.
The SleepImage App does not record, track, or share the user’s location. Android requires that we ask for this permission to notify you, because the Bluetooth technology can be used for location services.
The SleepImage App does not store any personal identifying information.
