12 Top Sleep Apps for Smartwatches (Free and Paid)

Sleep is a very important part of our overall well being. Whether you're simply curious about your sleeping pattern or you need it for health reasons, you'll get all the help you need from these sleep tracking apps that you can use on your smartwatch.

Sometimes it seems as if sleep is a secret cheat code to life. As with video games, finding the hidden sequence to a restful night can lead to extra energy and strength. Unlike video games, however, you can’t just consult the internet for the answer that works for every player. Accordingly, the search for effective sleep tools has raged on for hundreds of years, at least.

While we may not have arrived at the answer, at least today our advancements can help.  With wearable technology comes tools that can measure body movement and vital signals.  This allows us to create applications that can serve as diagnostic tools for sleep. While they are no substitute for actual medical advice, these sleep applications can bring us a lot closer to understanding how to get a good night’s sleep.

In general, sleep apps for smartwatches use three basic metrics to track sleep-related statistics.

  • Heart rate – Most of the applications designed specifically to work on smartwatches include some kind of heart rate tracking and analysis. This feature can be good for people looking for a more comprehensive look at overall health. The heart rate information while sleeping can be combined with other applications that monitor heart rate during exercise or otherwise daily activities.
  • Sound Analysis – Many of the applications also use some kind of sound analysis.  This can be useful for detecting specific sleep problems such as snoring or sleep apnea. Sound monitoring was also used in a number of devices to record body movements during the night.  These devices, of course, have limitations in terms of proximity to the sound, and the amount of actual noise. Snoring is generally loud enough to be heard at a distance. Sleep apnea, on the other hand, does not always result in audible sudden breaths. In addition, if the watch is held under blankets almost any noises can be difficult to hear.
  • Body Motion –  Assuming that sleep intensity changes can be recorded by actual movements, many applications track the motion of the body overnight. This can provide insight into actual waking periods, or just times when the sleep is light enough for movement. Generally, deeper sleep stages do not include as much movement of the body. Since body motion during sleep is a personal difference, several applications provide a way to indicate sensitivity to motion.

Most of the sleep trackers that work on applications outside watches only track motion and sound. Users will have to pay attention to make sure they select an app that is compatible. Users may find other applications that can work on multiple devices, including smartwatches. These applications make use of motion detection and sound features on watches but often lack the heartbeat monitor.

Please remember, applications are not a substitution for medical diagnoses.  While most of the applications provide varying degrees of tracking reports, many of the others also provide coaching plans. Obviously this review cannot indicate how effective these sleep improvement plans might be for each user. Sleep disruptions can be caused by a number of factors, and many users find comfort in solutions that do not work for others.
