The Apple Watch Series 3 has set a record for saving lives thanks to its ECG sensor, which is capable of detecting an irregular heartbeat.
Not to mention the fall detection feature, which will alert emergency services if it detects its user has fallen, has also saved a handful of lives.
The next feature coming to the Apple Watch might not save your life, but it will tell you how badly you're sleeping at night.
Apple spoke to some sources who claimed to have details on a sleep tracking feature - code named 'Burrito' - and how it'll work.
They also stated that it could be announced during the new iPhone launch which is slated to happen on September 10th, 2019.
The sources go on to say that the sleep tracker feature will work by relying on the watch's motion, heart rate, and noise detection.
A dedicated app will show you your sleep readings, a reminder to charge your watch before you sleep, and a useful feature that vibrates your watch to wake you up.
Interestingly, you can also inform the app which Apple Watch you're using to sleep.. if for some reason you own more than one Apple Watch.
This may be something new for the Apple Watch, but sleep tracking technology is already a mainstay in some Fitbit devices.
However, we aren't sure if you'll require an accessory for sleep tracking to work or they'll release it in the new Apple Watch.
But seeing as Fitbit can achieve sleep tracking with just a heartbeat monitor, we'll assume Apple will release this feature as a software update.
