Wear OS
Adapted from Wikipedia · Discoverer experience
Wear OS is a special kind of computer system made for smartwatches and other wearable devices by Google. It was first called Android Wear when it came out in 2014 and changed its name to Wear OS in 2018. This system works best when connected to phones that use Android or iOS, letting users get notifications and use helpful tools right on their wrists.
Wear OS can connect through Bluetooth, NFC, Wi‑Fi, and even cell networks like 3G, 4G, and LTE. It also works with Google Play, so users can find many apps and watch faces that come in round, square, and rectangular styles. Many companies like Asus, Fossil, HTC, LG, Samsung, and Xiaomi help make these smartwatches.
Since it launched, Wear OS has become popular. In 2014, over 720,000 smartwatches were sold, and by 2022, the Wear OS app had been downloaded more than 50 million times. By 2021, it was a big part of the smartwatch market, even though Apple’s watches were more popular. Today, Samsung is the main company selling Wear OS devices after switching back to it in 2021.
History and compatibility
The platform was first shown on March 18, 2014, with a preview for developers. Companies like Motorola, Samsung, LG, HTC, and Asus joined as partners. On June 25, 2014, at Google I/O, the Samsung Gear Live and LG G Watch were introduced, marking the first smartwatches to run Android Wear. The LG G Watch was the first to be released and sold, followed by Motorola's Moto 360 in September 2014.
An update in December 2014 added new features and changed the software to be based on Android 5.0 "Lollipop". More devices like the Asus ZenWatch, the Sony SmartWatch 3, and the LG G Watch R arrived by the end of 2014. By March 2015, newer models included the LG Watch Urbane and the Huawei Watch.
In 2015, Google introduced a Wear OS app for iOS version 8.2 or newer, letting users receive iOS notifications on supported smartwatches. In March 2018, Android Wear was renamed to Wear OS to better match its technology and vision. In September 2018, Wear OS 2.0 brought changes like a new Google feed and fitness tracking features.
In January 2021, Google finished buying the wearables company Fitbit, planning to invest more in Wear OS and bring new devices to the market. In May 2021 at Google I/O, Google shared plans for Wear OS 3.0. This update includes a new look inspired by Android 12 and Fitbit's exercise tracking. Google also partnered with Samsung Electronics to bring Wear OS to Samsung's future smartwatches. The update uses Android 11 and will be available for devices with Qualcomm Snapdragon Wear 4100 system on chip, needing a factory reset to install.
Features
Wear OS can show messages from a connected phone or tablet. Users can talk to the device by saying "OK Google" and can also use hand movements to give commands. It works with many Google services like Google Assistant, Google Mobile Services, Gmail, Google Maps, and Google Wallet, as well as apps from the Play Store.
From the watch's main screen, users can swipe up to see messages, swipe down to change settings quickly, swipe left to see news and interests, and swipe right to check activity and health details with Google Fit. The watch can track walking or running and, if it has a heart sensor, can check heart rate when asked or at set times during the day. It can also control music or videos playing on the connected device.
