Cover, maker of an Android lockscreen that displays apps based on what it thinks you need, just announced it has been acquired by Twitter.

With Google Now-like features, Cover displays different apps on your lockscreen depending on where you are. The company claims it “learns which apps you use most in each context.” More from Cover:

So when you’re in the car, maps are right there. At work, your calendar and documents are at your fingertips. You can set a custom ringer volume and wallpaper for each location.

Cover shares that it will work with Twitter to make smartphones “a lot smarter — more useful and more contextual.” The startup, which launched in October, is an interesting purchase for Twitter; the social network has expressed little interest in productivity services in the past. The focal point of this acquisition, according to Cover’s announcement, is Android.

For now, Cover’s app will live on, but neither company promises to keep it around forever.
