Smart watch and Wearable

Sleep as Android currently integrates Mi Band 1, 2 (with exception of Mi Band 1S), Pebble, Android Wear and Samsung Galaxy Gear devices and most of the BT Smart Heart rate monitors such as e.g. Polar H7.

WE SUPPORT XIAOMI MI BAND 1, 2 and 3 (with exception of Mi Band 1S) 

Download addons

  • Pebble (1 & 2, all variants)
  • Android Wear 1 will install automatically on your watch
  • Android Wear 2 app has tobe installed manually via Play Store on the watch (“apps on your phone” section)
  • Microsoft Band (1,2)
  • Samsung Gear 1, Gear S: install “Sleep As Android – Gear Companion” from Gear Store
  • Samsung Gear S2, S3 (not Fit and Fit 2): install “Sleep As Android – Native Gear Companion” from the Gear store
  • Xiaomi Mi Band all flavors (except Mi Band 1S Pulse): install either Mi Band Tools or Notify & Fitness

Sleep as Android also works on wearable Android smartphones such as iMacwear M7 out of the box.


General information

IMPORTANT: Smartwatch tracking needs to be enabled in Settings > Wearables > Sleep tracking (Use wearables)

The smart watch integration features:

    • Basic functions:
      • Vibe-alarm on watch – vibrating won’t wake your partner. Works even when the smartwatch loses connection to the phone.
      • Sleep tracking using the watch’s accelerometer – better data, more comfort than having the phone in bed
      • CAPTCHA – in case your phone is few meters from your bed, than all CAPTCHAs guarantee getting your laterally out of bed
      • Pause/snooze/dismiss control on your watch
      • Next alarm time right on the watch
    • Advanced functions:
      • Heart rate tracking for automatic awake and REM detection (only supported devices with HR sensor)
      • Smart wake up works as good as with phone only
      • Lucid dreaming vibes on watch
      • Anti-snoring (uses phone’s mic but vibrates on your wrist when you snore)
      • Lullaby volume down (fade out any of Your music or provided lullabies)

CAUTION: We recommend to still sleep track with airplane mode on, but Bluetooth needs to be enabled in order to make the connection between your watch and the app working. The recommended way is to switch on the airplane mode (which disables Bluetooth) and then switch Bluetooth back on

Supported devices

IMPORTANT: Your device is not in the list? We have an API to allow 3rd parties to integrate their device, please see our Wearable integration API.

We support all Android Wear and Wear 2.0 watches. They however differ in battery life – see table.

Pebble (all variants) YES <<10%
4-5 days without charging with sleep tracking each night
You need to install the Sleep as Android app from the Pebble App Store onto Your Pebble.

Best battery life among smart watches

Known issue:
after some time watch accelerometer may return zero values which leads to a flat graph, this has been approved to get resolved by resetting the watch.

For firmware version 2.9.1 and lower, please download the app here.

Best battery life among smart watches
 Sony SW3 (SWR50)  YES  ~15%182 events sensor batch queue which allows very low battery consumption (although default sensor frequency is higher than on Gear Live for example)Many thanks to Sony Mobile for their great help to overcome the sensor batching which got battery consumption from ~70% to ~15% per night. What is sensor batching?

Known issue: Sometimes gets into a broken state and starts using up to 100% battery. Reboot watch to resolve the issue.

Known issue: Sometimes the Wear app doesn’t install the app on your watch automatically. Sleep as Android then stays stuck on “Waiting for connectivity” and never connects. To resolve, go to Android Wear app > Settings > Your watch > Resync apps.

Samsung Gear Live inv_ic_action_love YES ~15%150 events sensor batch queue which allows very low battery consumption What is sensor batching?

Support heart rate monitoring!

There are issues with refurbished Gear Live devices with a dev version of the OS which do not connect to with Sleep as Android. Re-flashing of the firmware as described below should resolve the issue:

Samsung Gear Sport inv_ic_action_love YES ~20%
 LG G Watch YES ~20%Should be working well even the watch reports a batch size of size zero even sensor batching is supported in fact. What is sensor batching?
 LG G Watch R inv_ic_action_love YES ~15%Biggest sensor batch queue so far 10000 events. (What is sensor batching?) May allow us to do some further optimizations in the future..Support heart rate monitoring! 
 LG G Watch Urbane inv_ic_action_love YES ~15%Sensor batch queue 10000 events.
LG G Watch Sport inv_ic_action_loveYES~20%
 Moto 360 inv_ic_action_love  YES (but higher battery use) ~40%CAUTION: Does not support sensor batching and features an 2010 CPU with high battery consumption (What is sensor batching?)
RECOMMENDATION: Use theater mode to lower battery consumption!
EDIT2: Seems to get to reasonable battery consumption per night around 40% after the firmware update and fix for the sensor issue below. Still we get reports that on unknown occasions battery can peak at 70-80% for some days. Usually a reboot fixes this issue.EDIT: After the firmware update moto360 stops the accelerometer each few minutes, we have a workaround for this issue.
 Moto 360 V2 inv_ic_action_love  YES ~5%It seems that the Android Wear 2 version supports sensor batching.
 ZenWatchinv_ic_action_love YES (but higher battery use)  ~40% CAUTION: Does not support sensor batching (What is sensor batching?)
RECOMMENDATION: Use theater mode to lower battery consumption!
 ZenWatch 2 YES  6%, but ~50% on Android MHas sensor batching! Very good battery consumption reported, although not yet clear why it is so much better than other Wear devices.
Unfortunately Android M update for the watch broke sensor batching (What is sensor batching?).
ZenWatch 3YES ?
Galaxy Gear 1
Galaxy Gear 2
Galaxy Gear 2 Neo
Galaxy Gear S
 YES (but high battery use) ~60% (on Gear 2 and Gear 2 Neo)CAUTION: The accelerometer sensor only works with screen on with Gear 1 and 2, this together with no sensor batching support causes high battery consumption. Gear S allows to track with screen off but we don’t have realiable battery consumption results yet.In order to make it running, You need to download the latest Gear add-on from the Samsung Galaxy AppStore or the Gear manager on some devices. The exact name of the add-on is “Sleep As Android – Gear Add-On”. Some users reported that they couldn’t find it and they needed to narrow their search to “Health & Fitness”. Apps for Gear watches may only be distributed through the Galaxy Apps Store.

Special note for Gear 1 users: Your device must be running Tizen OS.

Galaxy Gear S2
Galaxy Gear S3
YESplease report You need to install an addon on your phone, and “Sleep As Android – Native Gear Companion” on the watch from the Gear store.
Garmin CONNECT IQ devices  inv_ic_action_loveYES – currently in BETA~10-15%  Garmin integration is currently in BETA test. You can install it normally from the ConnectIQ store.
Microsoft Band (1 and 2)YES ~60%You need to download an addon for this to work.

Heart rate monitoring

Apart from some Wear devices Sleep as Android supports gathering of heart rate data from Bluetooth Smart device such as e.g. the Polar H7. This feature needs to be enabled in Settings > Smartwatch. If HR data arrive you should see a inv_ic_action_love in bottom right on the Sleep tracking screen.

Your aggregated HR levels are available in the Sleep graph detail, they are used to better identify REM and Awake phases, see Awake detection for more details.

  1. Are you going to support withings (now branded as Nokia) activité ? I know it won’t be possible to support this watch for live tracking but would it be possible to use statistics from the watch (that we can see ok Nokia health mate application) in the sleep application?

    1. Hi Antoine, thanks for asking. We don’t plan currently to support Withings directly. You should be however able to connect Withings cloud with either Google Fit or S Health via We support reading sleep data from both Fit and S Health, so they will get imported then.

  2. Would you consider supporting the Garmin Vivosmart HR+? You seem to support most of their other devices and this one is not that different. Is it because it’s still too new?

  3. It works well on my Ticwatch S but I’m not getting heart rate monitoring even though it has a heart rate sensor. Strange since it is an android wear watch!

  4. Do you have by any chance any plans to include standalone Android Wear sleep tracking? It would he great not having two bluetooth enabled devices next to me while I sleep, and the possibility of putting the watch into flight mode would save quite a lot of battery.

    1. Hi Drakknar, we don’t have this planned currently, could you please add your suggestion to Thank you very much

    1. Hello
      if your Wear watch does not send HR to Sleep, the problem is most often a missing Sensors permission either on the watch or on phone. Make sure that both phone and the watch have these granted.

      a) to grant the permission to the app on phone, go to System Settings > Apps > Sleep > Permissions
      b) to grant the permission to the app on watch, just start Sleep on your watch and it will ask you for granting the permission

  5. For these integrations (specifically XIAOMI MI BAND 2) does this integration mean that the app will both use the band’s accelerator to measure the sleep quality and most importantly, use the watch’s vibrating alarm as the alarm rather than the phone’s sounds?

    This may be the most obvious yes or no ever, but I got burned by not reading the Fitbit specs enough only realizing that is did not even have a smart alarm after purchasing it.

    1. Hi Matt, thanks for asking!
      The answer is YES 🙂 when you use Miband (or any other watch/band with SAA), it will use the watch’s sensors and also vibrate the watch for alarm. You can actually set it however you want it, i.e. use the alarm on phone and sensors on watch or anything.

  6. Hi, it works on Samsung Gear Sport with Sleep as Android Gear Addon. Battery consumption is 30% at night (7 – 8 hour sleep). Only disappointment is that connection is lost quite often (red line) … which doesn’t happen during the day(phone-watch).

    1. Hello, the device I’d currently recommend would be Xiaomi Miband 2. It’s unobtrusive, cheap, reliable, and has by far the best battery life.

  7. Sleep for android is a great app and you have really good customer interaction! Looking forward to future developments and integrations.
