Android: Cover is an adaptive launcher for Android that uses the time of day and your location to automatically show you relevant apps and information. Whether you're at work, at home or in the car, you'll see apps you typically use in each of those situations.
Cover pays attention to the apps you use at various points of the day (and lets you tell it when and what apps you prefer to use in what situations), then creates a custom lock screen with quick shortcuts to the apps you use most often at the right times. For example, at the office you'll see your email client, your calendar app and Dropbox. When you're in the car on the way home, Cover will surface your music player and your favourite GPS app. When you get home, it might bring up Facebook or Twitter, or show you the app you use as a remote control for your TV.
The lock screen can be further customised to include shortcuts to common tools such as your camera. When you do slide to unlock, you go back to your normal app launcher. Finally, each app shortcut on the lock screen lets you preview" that app; if you just want to see if you have new messages, you can tap and hold the Gmail icon and start to slide it out of the way, and you'll get a sneak peek at your inbox.
Cover hides a lot of power under a really simple and easy-to-use interface. Hit the link below to give it a try; it's available free for Android 4.1+ devices.
