Tracking your sleep on the app

If your wearable has been paired with the Healthy 365 app and it supports sleep tracking, you can click on the ‘Sync now’ button (as shown below) on the dashboard to track your sleep:

FAQs about using Apple watch sleep tracker and Fitbit sleep tracking to sync data

For Fitbit and Apple Watch (series 3 or later) users, please sync your watch with your Fitbit or Apple Health app first before launching the Healthy 365 app to sync.

The HPB fitness tracker can store up to 7 days of sleep data. Remember to sync your tracker to the app once every 7 days to avoid losing your sleep records.

Sleep sessions can only be tracked on the Healthy 365 app if there was a minimum of 2 consecutive hours of sleep detected by your tracker.

For HPB fitness trackers

The trackers will automatically track sleep duration based on changes in body movement and heart rate. For more accuracy in tracking your sleep,

  • Turn on the tracker and ensure it has sufficient battery. There is no need to activate the sleep tracking function.
  • Make sure the sensor on the back of the tracker is clean, dry, and free from foreign objects.
  • Wear the tracker at least 1 finger width away from the wrist bone. Tighten the band so it is snug but not too tight. This helps the sensor stay in contact with your skin.
  • Wear the tracker for at least 30 minutes before sleep and after waking up. However, please do not swim or shower with it as it is not waterproof.
  • When not wearing the tracker, place it with the screen facing down to avoid affecting the sensor on its back.

If you still experience problems with tracking sleep on your HPB fitness tracker, email hpb_mailbox@hpb.gov.sg or call 1800 223 1313.
*Airtime charges apply for mobile calls to 1800 service lines.

For commercial trackers

Ensure your sleep session is reflected on your commercial app before launching the Healthy 365 app to sync. Please note that only sleep sessions recorded by your tracker will be reflected on the Healthy 365 app. Sleep sessions that are manually recorded on the commercial app will not be captured by the Healthy 365 app.

Visit the links below for more information on tracking sleep using your commercial tracker:

The HPB fitness trackers are provided as a public service and are meant to provide participants with information to encourage an active and healthy lifestyle.

Third party testing has been carried out, and as with any commercial devices, the trackers are intended to be a close estimation of sleep metrics but may not be 100% accurate. Do also note that HPB fitness trackers are not medical devices and the data provided is not intended to be utilised and/or relied on for medical purposes. For tips on how to track sleep accurately using the HPB fitness tracker, please refer to the section on Ensuring accuracy in tracking sleep.

Viewing sleep records on the app

To view your sleep records, tap on the sleep icon to view your Sleep History. Sleep History includes previous sleep sessions synced.

Daily sleep record is captured between 12 noon to 11:59 am (following day). Do note that your sleep records on the dashboard reset at 12 noon daily and if you have synced your sleep records in the morning and see that the sleep arc was filled, this arc will be reset at noon.

If you have synced your wearable only after 12 noon, it will not be reflected on the dashboard but will be available under your Sleep History.

For example, if you wore your device to sleep on Sunday night and synced your sleep the next morning at 10 am, you would be able to see sleep synced on your Healthy 365 dashboard. However, if you synced or viewed your Healthy 365 app after 12 noon, you will need to tap on the sleep icon to view your Sleep History for the previous day.

To view your sleep for previous day, please tap on the sleep icon to view your Sleep History, and toggle to view by ‘Days’. You should see a sleep bar for the previous day. You can also tap on the bar to view further details of the day’s sleep.

Sleep records are viewable on the app for up to 3 months. Hence if you had participated in the Sleep Challenge in 2021, your past sleep data will not be carried over.

For HPB fitness trackers

Sleep duration will not be shown on the HPB fitness trackers. To view sleep duration, go to the Healthy 365 app and view “My Daily Progress”. To view your Sleep History, tap on the Sleep icon. Note that sleep duration can only be recorded if there are at least 2 consecutive hours of sleep clocked. Daily sleep record is captured between 12 noon to 11.59 am (following day).

For commercial trackers

To view your sleep duration, sync your tracker with your commercial app first before launching the Healthy 365 app to sync. Thereafter, you can view your sleep duration on both the commercial app and the Healthy 365 app*.

*For Fitbit users, kindly note that the sleep duration currently reflected on the Healthy 365 app displays the total time the user is recorded to be in bed. Hence, the sleep session might appear to be slightly longer in the Healthy 365 app for Fitbit users as compared to sleep recorded on the Fitbit app.
