Do you also wear your Apple Watch at night? In that case you get a handy function with Watchos 26, because you will see your sleep score in the Health app every day. This score is based on various factors. The Apple Watch records how long you sleep, how often you wake up and the duration of every sleep phase. The smartwatch also looks at the moment that you go to sleep every day and to what extent that happens at different times.
The Apple Watch keeps track of all this data, which is ultimately converted to a sleep score. You can also see the new function in the sleep app on your Apple Watch from Watchos 26. There you can see every day using your sleep score how good your night’s rest was. Did you sleep badly? In the Health app on your iPhone and the sleep app on the Apple Watch you get tips on how to get a better night’s sleep next time.
