At the annual I/O developer conference in April 2016, Google previewed two new mobile apps: a one-to-one video calling app called Duo, which released in mid-August, and a messaging software called Allo, which surfaced on the App Store this morning as a free download.
It sports features commonly found in messaging apps and includes a built-in Assistant, Google's conversational artificial intelligence helper, an Incognito mode and more.
While Google originally promised Allo would only store messages transiently and in non-identifiable form, the firm's had a change of heart as Allo logs all chats by default.
