Google's Allo is similar to Facebook's smartphone app Messenger, but with a twist. It has the same smart Google Assistant as Google Home built in.
That means you can message your friends and simultaneously ask Google Assistant to look up the nearest coffee shop or tell you where a movie is playing. Allo's chatbots will provide "smart replies," which suggest one touch responses to messages. For example, if your friends send you a picture of them on a beach it might reply for you, "Have fun!"
Security bonus: One major feature of this app is end-to-end encryption. Allo will use the same encryption protocol that Facebook's WhatsApp uses. That means your messages are nearly impossible for a hacker to see when you're in Incognito Mode.
