To put it simply, sleep tracking helps you understand not only how you sleep but also identify trends or factors that could be contributing to poor sleep quality for a single night or in general. Some of these insights can be viewed on the Apple Watch in the dedicated Sleep app, but most are found in a sleep subsection of the iOS Health app.

Smartphones and other gadgets are used not only as smart devices, but also for the intended purpose of the phone - it is a GSM connection. and if you want to receive SMS to virtual numbers, you can go to the website https://simonline.su/en through the same smartphone and use free phone numbers 

As already mentioned, there are a bunch of third-party Apple Watch sleep apps, which you will still see recommended to you in Apple’s Sleep app. This is the first time Apple has created something that uses both its smartwatch and iPhone to smarten up that bedtime experience.
