The Forerunner 35 displays your current and resting heart rate
The Garmin Forerunner 35 is a smartwatch that can track your sleep statistics and heart rate. While the watch itself can display your current and resting heart rate, some users have reported issues with the data not being transferred to the Garmin Connect app. This issue has persisted despite users trying multiple synchronisations, unpairing and re-pairing their devices, and even performing a factory reset on the watch.
The Forerunner 35's heart rate monitor displays your current heart rate in beats per minute (bpm) and also shows your resting heart rate for the day. This data is accessible directly on the watch and can be useful for those interested in tracking their heart rate alongside their sleep patterns.
Sleep tracking on the Forerunner 35 is possible through its built-in accelerometer, which can determine when you are asleep, the sleep stage you are in, and when you wake up. While this feature is available on the watch, more advanced Garmin devices also include an optical heart rate sensor, which provides more detailed sleep stats by measuring heart rate and heart rate variability in conjunction with the accelerometer data.
The Forerunner 35 allows you to view your sleep statistics on your Garmin Connect account, providing insights into your sleep patterns and duration. However, as mentioned earlier, some users have encountered issues with the heart rate and sleep data not being available in the app, even after multiple attempts to resolve the issue.
Despite the reported challenges with data synchronisation, the Forerunner 35 offers a combination of sleep tracking and heart rate monitoring features that can provide valuable information for users seeking to understand their sleep habits and overall health.

The Garmin Connect app may not show your heart rate data
The Garmin Forerunner 35 does provide sleep tracking, and it also displays your current heart rate in beats per minute (bpm) and your resting heart rate for the day. However, it is unclear whether the device uses heart rate for sleep tracking.
- Check if the heart rate (HR) shows on your watch. Ensure that your watch is functioning correctly and displaying your HR.
- Confirm that your watch is properly synced to the app. Data syncing issues could be the reason why your HR data is not showing up on the app. Try disconnecting and reconnecting your phone and watch, and then resyncing them.
- Restart your watch. Try powering off your watch and then powering it on again. This has resolved the issue for some users.
- Check if the web version of Garmin Connect shows the HR data. Access your Garmin Connect account on a web browser and see if your heart rate data is visible there.
- Ensure that your watch is set as the preferred tracking device and that activity tracking is enabled.
- Try syncing your watch to the app using a USB cable instead of a wireless connection.
- Refer to the Garmin support document titled "Data is Missing from My Garmin Account After Syncing" for troubleshooting steps. This document provides guidance on resolving data syncing issues.
If none of these solutions work, you may need to reach out to Garmin customer support or seek further assistance from Garmin forums or community resources.

The Forerunner 35 does not have a sleep monitor
The Garmin Forerunner 35 does not have a sleep monitor. While the watch can display your current heart rate in beats per minute (bpm) and your resting heart rate for the day, it does not have the capability to track your sleep.
Users have reported issues with the Garmin Connect app, stating that they are unable to view their sleep data and heart rate data. This issue appears to be specific to the app, as the watch functions correctly. One user reported that they were able to resolve the issue by unpairing their phone from the watch, deleting the app, restarting their phone, reinstalling the app, and then repairing the phone with the watch.
It is worth noting that other Garmin devices, such as the Garmin Instinct 2, the Forerunner 955, the Venu 2 Plus, the Garmin Fenix 7, and the Garmin Epix Gen 2, do offer detailed sleep tracking features. These devices typically have optical heart rate sensors that enable them to access and provide detailed sleep statistics.
While the Forerunner 35 may not offer sleep monitoring, it does provide other useful activity tracking features. For example, it can display your current and resting heart rate, as well as track your steps and other fitness-related metrics.
If sleep tracking is a priority for you, it may be worth considering upgrading to a different Garmin device that specifically offers this feature. These devices are designed to help you better understand your sleep patterns and make improvements where necessary.

Other Garmin devices with optical heart rate sensors can access detailed sleep stats
The Garmin Forerunner 35 does offer sleep tracking. You can view your sleep statistics on your Garmin Connect account. However, it is unclear whether the Forerunner 35 uses heart rate for sleep tracking. While the device can display your current and resting heart rate, it is not specified if this data is used for sleep tracking.
Garmin's sleep tracking technology relies on detecting changes in physiological markers such as heart rate, restlessness, and heart rate variability to determine your sleep stages, including light, deep, and REM sleep. This allows Garmin to provide insights into your sleep quality and duration. For optimal restorative benefits, Garmin recommends targeting 17-35% of total sleep time in the deep sleep stage.
While Garmin's sleep tracking can offer valuable insights, it is important to note that it cannot diagnose sleep disorders. Instead, the data can help detect unusual patterns that may be worth consulting a medical professional about. Additionally, some Garmin devices with SpO2 sensors can monitor your blood oxygen saturation throughout the night, which can indicate the efficiency of oxygen transport in your body and help identify potential sleep issues.
