You no longer need to try a beta to stream Android apps on your Chromebook. Google has released a Chrome OS M115 update that makes Android app streaming available to many more people. If you have Phone Hub enabled, you can run an Android app directly from your mobile device rather than installing it on the computer. The update allows you to reply to a message or check your lunch delivery without the distraction of reaching for your handset.
The feature is still limited to a handful of Android 13-capable phones from Google and Xiaomi. From Google, you'll need a Pixel 4a or later. Xiaomi fans, meanwhile, need at least a 12T. Both your Chromebook and phone must be on the same WiFi network and physically close by. Some networks might not support the feature, but you can use Chrome OS' Instant Tethering to establish a link if need be.
As during the beta, you won't want to use app streaming for games or other intensive Android apps. This is more for responding to notifications than any serious commitment — you'll still want to install apps for that. It gives Chromebooks some of the phone integration you find in macOS and Windows, though, and may help you stay focused while you work.
The M115 upgrade also lets you sign PDF documents and save signatures to use later. Google has also redesigned the keyboard-oriented Shortcut app with a new interface and easier in-app search.
