Google has mandated that all Wear OS applications must include a 64-bit version starting September 15, 2026. This requirement is part of a broader strategy that also applies to Android TV and Google TV, which will require 64-bit app versions from August 2026. Developers can still offer a 32-bit version alongside the new 64-bit applications, and the Play Store will continue to support legacy applications. A majority of Wear OS developers have already adopted the 64-bit architecture, although some dormant apps may present challenges. The transition to a 64-bit architecture is expected to enhance performance, security, and efficiency for chip manufacturers, as well as allow smartwatches to utilize more than 4GB of RAM.
