Allo and Duo aren't available yet, but you can now pre-register for Google's new messaging apps.
Update: The pre-register links are working again.
Allo, Google's new messenger app that brings in the intelligence of Google Assistant, was one of the highlights of today's Google I/O keynote. Together with Duo, the new video calling app, they represent the next step for Google's messaging efforts. And although they're not yet available, you can now sign up to receive a notification when they do lad.
"Pre-registration" pages for the apps have appeared on the Google Play Store following the keynote. Tap the button and Google explains how it all works:
"You're about to pre-register for Allo by Google. Pre-registering means that you will receive a notification on your device when the app is released. You can unregister by clicking the 'Unregister' button."
Allo and Duo are set to launch later this summer.
