It's common-sense to protect the data stored on our phones and tablets, but doing so shouldn't make them any less convenient in use. Having to key in a passcode or draw onscreen a pattern each time you want to use your device can be a real pain. I don't want others to nosey through my messages or tell my Facebook friends I'm on the loo, yet I have nothing to hide in many of my other apps and absolutely no problem should someone want to pinch my phone and complete the next level of Candy Crush Saga.

AppLock is a great solution to this problem, letting you lock down only the apps to which you want to avoid prying eyes. You simply install the free Android app, set up a passcode, then toggle on or off the sliders in the list of installed apps. AppLock can also prevent others from installing or uninstalling apps, force-stopping the app and answering incoming calls.

A premium version of AppLock (59p/month or £1.95/year) includes extra features such as the ability to lock apps in a given location or at a certain time, set up profiles and more.
