Google has officially announced a significant update for developers working with Wear OS, aligning its requirements with the broader trend across its platforms. 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. This move follows a similar mandate for Android TV and Google TV, which will also require 64-bit app versions starting this August.
Google requires 64-bit apps for Wear OS
Developers have a window of opportunity to adapt their applications to meet this new standard, as Google has indicated that the Play Store will begin blocking uploads of non-compliant apps after the deadline. Notably, the tech giant has observed that a significant number of Wear OS developers have already transitioned to 64-bit compliant apps, with many available on the platform.
For those still utilizing smartwatches running on a 32-bit version of Wear OS, Google has reassured users that there will be no immediate changes to the support policy for these devices. The Play Store will continue to deliver apps to existing 32-bit devices, ensuring that current users are not left behind during this transition.

The introduction of 64-bit app versions alongside 32-bit versions could signal a pivotal shift in the future of Wear OS. There is speculation that this requirement may eventually evolve into a 64-bit-only standard, mirroring the trajectory seen with Android, where Google mandated 64-bit app versions in 2019 and transitioned to a 64-bit-only architecture with Android 14 in 2024.
Google emphasizes that “64-bit architectures provide performance improvements and a foundation for future innovation.” This transition is expected to enhance security, as features like memory tagging extensions necessitate a 64-bit platform. Additionally, a 64-bit system will enable smartwatches to utilize more than 4GB of RAM, paving the way for more advanced applications and functionalities in the future.
