As of September 15, 2026, all new apps and updates for Wear OS must include a 64-bit version in addition to the existing 32-bit version. The Play Store will block uploads of non-compliant apps after this deadline. Current users of smartwatches running on a 32-bit version of Wear OS will continue to receive app support. The introduction of 64-bit app versions is expected to improve performance, enhance security, and allow for the use of more than 4GB of RAM in smartwatches.
