In a significant move, Google is extending its 64-bit app requirement to Wear OS, marking a pivotal moment for developers and users alike. As of September 15th, 2026, all new applications and updates for Wear OS on the Google Play Store must include a 64-bit version alongside their existing 32-bit counterparts.
Google Requires 64-bit Apps for Wear OS
This announcement follows Google’s prior mandate for Android TV and Google TV, signaling a broader commitment to enhancing app performance and security across its platforms. Notably, Google has indicated that a majority of Wear OS developers are already complying with this requirement, and numerous 64-bit compliant applications are currently available on the Play Store.
For developers, this transition presents an opportunity to improve app efficiency and leverage the enhanced capabilities of 64-bit architecture. It’s important to note that Google Play will begin blocking the upload of non-compliant apps after the September deadline, emphasizing the urgency for developers to prepare for this change. Fortunately, developers have a few years before compliance becomes mandatory, allowing ample time for necessary adjustments.
Delivery of Apps to Existing 32-bit Devices Will Continue
For users who still utilize smartwatches with a 32-bit version of Wear OS, it’s crucial to understand that Google is maintaining its stance on 32-bit support. The company has assured users that Google Play will continue to deliver apps to existing 32-bit devices, a considerate approach as many users are still reliant on these older models.
However, the introduction of a dual architecture requirement may signal a shift toward a future where 64-bit becomes the standard. Reflecting back, Google initially mandated 64-bit app versions for all Android applications in 2019, as Android 14 is poised to transition entirely to a 64-bit-only architecture by 2024. Given this trajectory, it is possible that Wear OS could eventually phase out 32-bit support altogether.
Embracing 64-bit technology presents numerous advantages. Google has stated that “64-bit architectures provide performance improvements and a foundation for future innovation.” This transition is not only about boosting performance; it also enhances security through features like memory tagging extensions that necessitate a 64-bit platform. Moreover, a 64-bit architecture allows smartwatches to utilize more than 4GB of RAM, paving the way for richer applications and experiences in the future.
