Twitter on Monday announced it had acquired Cover, a small startup focused on smart suggestions of Android apps for users. The startup, which launched just six months ago, will join the microblogging company at its San Francisco headquarters. Cover deals with an interesting subject area: Using your smartphone’s sensors to determine context and offer suggestions on what sort of Android apps you may want to have fast access to throughout the day. So if you’re passing a coffee shop at which you normally use the Venmo app to pay, Cover will rely on your phone’s location sensors and the time of day and serve up that Venmo app to the cover screen of your Android phone. That isn’t to say Twitter is going to do a one-to-one translation of Cover’s features (Twitter has made a bunch of small acquisitions in its history, sometimes for talent, sometimes for tech).
