Twitter bought Cover, the experimental lock screen that you can download exclusively on the Google Play Store. Cover is a lock screen that uses your location positioning system (GPS) on your android device to tell where you are. For example say if your home and you only use a couple apps at home, those apps will always show up on your lock screen when you are at home, also if you go out, Cover knows what apps to recommend to you while you’re out and traveling. Let me get into what this transaction means for Cover and their customers using it in the beta testing right now. Twitter wants to merge cover with your twitter account, say a natural disaster happened in your area, cover would be able to show tweets about it from other tweeters in your area on your lock screen. This is sort of the kind of notification system ios users have with “Push Notifications”, So if you want a smart lock screen for your android device definitely try out Cover.
