I recently launch Smart Lock in the Android Market. YouTube - Smart Lock Overview - Child Lock Smart Lock lets you Child Lock your phone, increases general security, makes the lock screen more useful, makes the camera boot up faster and even helps you improve battery life. Smart Lock runs in the background and lets you use one application without seeing the lock screen. The main feature is the Child Lock feature. You can give your phone to your child and not have to worry about them deleting info on your phone, changing your settings or viewing inappropriate material. You can limit there access to only one application. Smart Lock is also great for anyone that likes to keep their phone secure, but finds it annoying to enter the unlock pattern every time they turn the screen on. I use it at the gym when I'm listening to music. It lets me change songs easily without compromising security. Smart Lock also dramatically speeds up camera boot time on older Android phones. Because it bypasses the lock screen you don't have to wait for the screen to orient into landscape mode before taking pictures. The camera goes from screen off to taking pictures almost instantly. I am currently offering a Early Adopter sale of Smart Lock. Its only 99 cents, but the price will go up soon so get it while the sale lasts.
