sleep tracker

The tech giant also announced a new atrial fibrillation history feature and sleep stage tracking.

Back in June, Apple announced that sleep tracking was finally coming to the Apple Watch. But it's not just tracking: It's a whole sleep experience. In this video, HIMSS Media Editor in Chief Jonah Comstock tries it out.

The technology includes an EEG, heart rate monitor and movement tracker. 

The company has collected more than 10.5 billion nights of sleep data over the years, which helped them to provide insights on Singaporean users.

Launching in 2020, Pokémon Sleep will feature gameplay that responds to the player's sleep habits.

The filing is a strong indication the Cupertino tech giant isn't done with standalone sleep monitoring devices.
