Google will force Wear OS to transition to 64‑bit applications.

Google is moving the Wear OS and Android TV ecosystem to a 64-bit architecture

*What’s changing*

- Starting in August, 64-bit versions of apps will be required for Android TV and Google TV devices.

- Soon the same requirement will apply to Wear OS.

*Key dates*

- September 15, 2026 – all new apps, as well as updates to existing ones, must be published in a 64‑bit format (alongside the 32‑bit version).

- Apps that do not meet this condition will be blocked on Google Play.

*Why it matters*

- Many smartwatches still run the 32-bit version of Wear OS, making it difficult for the entire platform to transition to 64-bit.

- However, “the overwhelming majority” of developers have already integrated 64‑bit versions of their apps, according to Google.

*Development path*

- Because the requirement for having 64‑bit versions alongside 32‑bit ones led the entire Android ecosystem to adopt a 64‑bit architecture (Android 14 in 2024), a similar outcome can be expected for Wear OS in the coming years.

*Benefits*

1. Improved performance – more efficient use of resources.

2. Security – the 64-bit platform supports memory‑tagging technologies, increasing resilience against attacks.

3. Expanded memory capabilities – devices will be able to work with up to 4 GB of RAM, which becomes relevant as local AI models are deployed.

Thus, Google intends to make Wear OS and its related services fully 64‑bit to enhance both app efficiency and user security.
