Around that time, Google Keep looks to have dropped support for older Wear OS 2 devices.
These old devices also never got the new Google Home or Contacts, while the updated Assistant, Phone, and Weather are limited to Wear OS 3.Original 11/24: Currently, searching for Google Keep in the Play Store using a Wear OS 2 watch does not show the app.That revamp arrived in September just after a tile to quickly create notes or list was introduced.(That tile later received a Material You overhaul, but do note — sorry — how the text of the “Browse” button is not vertically aligned. For some reason, the tile preview is correctly centered, but the actual tile is not. Meanwhile, the Apple Watch app has not seen any updates and is still using the pre-Google Workspace icon.).
While there are more Wear OS 3 devices than ever from the Pixel Watch to Galaxy Watch 5/4 and Fossil Gen 6, the active Wear OS 2 user base is likely not insignificant, even if it’s just those awaiting updates.
Looking at a Wear OS 2 device today, the following first-party apps are available: Google, Gboard, Fit, Wallet, Messages, Camera, Clock, Wear OS by Google Smartwatch, and YouTube Music.
