LOCKit is a free utility application for mobile created by Super Tools Corporation. It is a privacy lock tool that will let users secure apps and media files inside a virtual password-protected vault for safekeeping. It prevents others from accessing and opening things they're not supposed to.

Similar to AppLock or HideX: Calculator Lock, LOCKit makes it simple for users to hide and secure any sensitive and personal data. It boasts a clean and intuitive user interface that is easy to learn. It even comes with various tools to help optimize the performance of their devices.

Everything under lock

LOCKit is basically a handy tool you can use to prevent your files from being accessed, as well as applications from being opened and used. In this day and age when you take photos and videos more than ever, you wouldn't want your private media to be seen by other people who happen to borrow your smartphone. This app was made exactly for those types of scenarios.

You will get virtual Photo and Video Vaults to store and hide them away with your preferred password or biometric authentication. If you have applications that you don't want others to open like your gallery or messages you can implement the same security measures. There are even features called Fake Cover that show error message popups and Intruder Selfie that will take a photo of anyone trying to crack your password.

The app features some nice extras, including theming options and hiding notification previews. There's even a system cleaner to help clear out system cache, delete leftover files, and free up RAM. The thing is, though, these features are common and already included in most smartphones today, making this particular app somewhat redundant and unnecessary. If you don't have these on your phone, then this can come in handy.

Lock it down

If you're in need of a way to keep your applications from being used and your media from being seen, LOCKit is a good security measure that you can implement. It's easy to use, comes with various options, and just works as intended. However, most of the features it has are already baked into most smartphones today. Check your device first to avoid redundancy and duplication.
