We're still waiting for the official debut of Google's Allo app, which the company announced earlier this year at its I/O developer conference. Duo, the company's video-calling app that it also announced at I/O, is already live on the Google Play Store, but we have yet to see Allo make its debut (nor do we have a precise timeline for when Allo might ship).
We do, however, have some new alleged leaks that show off parts of Allo's interface. Though the app is designed to let you chat with your friends in all sorts of ways—including simple messaging, sending stickers and graphics, and doodling on photos—the new leaked images of Allo's interface center on the app's voice messaging elements. And if you've ever used WhatsApp to trade voice messages with a friend, the process should look pretty familiar.
As Android Police notes, Allo's voice messaging feature allows you to quickly and easily record messages to send. If you don't want to send a person a text message, just press your finger on the microphone icon to the right of Allo's text box. You'll have to hold your finger on the icon while you're recording, because your message will fire off to your friend as soon as you let go. If you want to cancel whatever it is you recorded, just move your finger to the left of the app's UI.
It's possible that this interface might change once Allo is officially released, as Android Police was only sent screenshots (and animations) from a test version of the app. While the interface itself looks a bit cleaner than WhatsApp's, the latter does come with an extra animation for whenever you're cancelling a voice message: the blinking red recording icon flies up into the air and back down into a trash can. Cute.
Allo isn't just meant to be a WhatsApp clone, though. The app is going to rely on Google's machine learning expertise to help suggest replies to the various messages your friends send you. Depending on how you normally converse with people, including the various emoji and stickers you use, Allo should be able to learn your patterns and offer you some unique suggestions for what you might want to say on the app.
That, and a built-in digital assistant (Google Assistant) will work to offer you topical suggestions based on what you and a friend talking about. If you are both trying to figure out the best place to eat in a particular area, Google Assistant might try to offer some helpful suggestions at the bottom of your chat window, for example. You can even talk to Google Assistant directly in a chat, if you want more of a conversation than a drop-in suggestion.
