What people thinks

Most accurate

Tomas mi

"I like this app because it is simple, has a lovely interface and most importantly is accurate in detecting when I fall asleep and when I was awake in the middle of sleep. If you are looking for a sleep tracker and a smart alarm, it should work for you"

Great app & beautifully designed!

JT121

"I love this app! Much better data and visuals than the native Health app! Seems to be even more accurate than my Sleep Number bed data. I was using this with my Apple Watch series 4 (worked great) and just got the new series 6. Amazing job, hats off to the developer."

Literally, the best sleep monitor app I have used

Desert Passion

"For the past five years I was using a Fitbit Charge, Blaze, and Versa 2. At first I missed the Fitbit app because it had all my statistics in one app. This app is so accurate. If you’re shopping for a great sleep monitor app, this one will not disappoint."

FAQ

“No Sleep Session Detected” error means Rem couldn’t capture the data to perform sleep analysis.

Have you installed the latest version of Rem?

Make sure you have the latest version of Rem installed.
Here's How:

Open the App Store
Go to your profile
Check for any available updates for Rem

Do you wear your Apple Watch during sleep?

Rem analyses the Apple Health data collected by your Apple Watch while you sleep. If you do not wear your Apple Watch during sleep, then Rem CANNOT perform sleep analysis. There’s no need to launch the app to collect the data, your watch will collect it automatically while you sleep.

Did your Apple Watch register any data?

Sometimes your Apple Watch may fail to register or transmit data to your iPhone. To check that your Apple Watch is registering data:

Open Apple Health on your iPhone
Go to the “Browse” tab
Go to “Vitals” > “Heart Rate”sdsdfdf
Scroll down and go to “Show all data“
Select the day that you wore your Apple Watch during sleep

There should be records made by your Apple Watch during the time you were asleep, roughly every 3-10 minutes.

If there is no data for either ‘Heart Rate’ or ‘Active Energy’ then there may be a hardware issue with your Apple Watch, or it may not be properly configured. Here’s how to check for these issues:

Is Bluetooth turned ON?

Rem relies on Apple Watch data being transmitted to your iPhone via Bluetooth or Wifi, so please ensure that both are switched ON. The data transmission is handled automatically by watchOS. It may take 2-10 minutes to transmit all required data, especially if your Apple Watch has a low battery.

Is Airplane mode enabled?

If your device has Airplane mode enabled your Apple Watch will not be able to communicate with your iPhone. You can still use Airplane mode whilst you sleep, but you will need to turn it off when you wake up to allow your Apple Watch to finish transmitting data (this may take a couple of minutes).

Is your Apple Watch Pass-code protected?

Remember, you will need to enter your pass-code before going to sleep to ensure your sensor data is accessible.

Is “Wrist detection” enabled?

Heart rate data needed for sleep analysis will not be recorded by your Apple Watch unless wrist detection is turned on.
To enable wrist detection:

Open the "Watch" app on your iPhone
Go to "Pass-code"
Turn on "Wrist Detection"

Did your Apple Watch go into power saving mode?

Your Apple Watch will go into ‘Power Saving Mode’ if it is running out of battery. This will turn all sensors off, so no data will be registered.

Do you wear your Apple Watch loosely or have any tattoos on your wrist?

Wearing your Apple Watch loosely will stop it from recording your heart rate properly.
Any large tattoos on your wrist may also affect your Apple Watch from recording data properly.
