Maybe you didn't catch the news at this year's Google I/O conference, but Google's developed a fascinating tool for enablingcalled Cloud Anchors, which syncs positions across devices. It even works across iOS and Android.
The Just A Line app already existed on Android, and is a doodling app in AR. But the app just went live on iOS, too, and is Google's first Android-to-iOS AR experiment.
To work, both phones trying the collaborative doodling need to be near each other, and then can pair in-app to begin doing ARdoodles together.
Download it (I am), and try it out. Maybe we'll see a lot more of these to come. See below for Cloud Anchor AR games I tried at Google I/O a few weeks ago.
