Its only drawback is its use of Samsung’s own Tizen OS. Tizen is a custom OS that’s based on Linux. On paper it’s pretty good, letting you pair the Gear S2 with any Android smartphone, not just Samsung Galaxy phones. But it’s nowhere near as developed as Wear OS, which itself isn’t perfect. There aren’t nearly as many apps available as the Wear OS app store, but the core functionality is at least present from what is available.
The MetaWatch M1, like the Cookoo 2 and Martian Notifier, is a basic smartwatch.

For all of you outdoorsmen, Casio returned to IFA this year with its latest Pro Trek watch. The Casio WSD-F30 takes the same great features of previous generations and slaps them inside of a slightly slimmer body. The 60.5mm × 53.8mm × 14.9mm body is still pretty huge, but it’s considerably smaller than what came before it and still maintains 5ATM water resistance, MIL-STD-810, and even low-temperature resistance.
Samsung released its Galaxy Watch, a follow-up to the Gear S3, a prior pick. The Galaxy Watch is available in 42 mm and 46 mm configurations, with either a Bluetooth-only connection or Bluetooth plus LTE from T-Mobile (at launch). The biggest update seems to be the battery life, which the company claims will last for days between charges. The Bluetooth version of the Galaxy Watch is available for $330 for the smaller version and $350 for the larger (46 mm) model; the 42 mm LTE version is available for $380 and the 46 mm is $400.
In China, since around 2015, smartwatches have become widely used by schoolchildren. They are advertised on television throughout the country as a safety device whereby the child can call in case of emergency. The devices are commonly colorful and made of plastic. They normally have no display unless a button is pushed. These smartwatches have limited capability compared to other smartwatches; their main functions consist of being able to conduct calls, displaying of time, and sometimes have air temperature sensitivity. They cost around $100 to $200 USD.

Even more importantly, Apple received FDA clearance for a new electrocardiogram feature that can take a 30-second EKG and diagnose atrial fibrillation.
