For security – AppLock

AppLock

AppLock is an app that locks apps. That’s a pretty simple definition of course, but it’s an impressive little program. It lets you lock up the apps on your mobile and tablet for added security on those things you want keeping hidden. That means your private notes can be safely locked away, you add a layer of security to your banking apps and your kids will learn to keep their sticky fingers away from your Candy Crush.

AppLock is only available for Android 6.0+, so you’ll probably need a newer device like the Samsung Galaxy Tab S2.

It incorporates a ton of plug-ins so that you can move emails into other apps like Evernote to get more work done. Add that to its easy gestures for mass marking, or deleting emails and it comes out as one of the, if not the, very best email clients on Android.
