Best applock and lock screen apps for Android

The screen lock is the first line of your Android security. It isn’t an impenetrable measure (a factory reset can bypass that), but it still shields up your device and makes it inaccessible to your friends or a jealous partner. Every Android has a standard screen locker that lets you lock your phone with a passcode, a pattern lock, or a four-digit PIN.

Manufacturers often equip their devices with their custom screen lock apps that are built into the system or make use of the already-available Android alternative. Albeit there is nothing wrong with standard lock screens, but other Android lock screen apps offer useful navigational features to let you instantly jump from one app or service to another, and also sport eye-catchy designs and patterns to make unlocking your phone a fun time.

CM Locker


CM Locker is the most secure screen lock for mobile you can have. This app functions as a mini antivirus for Android as it is equipped with features that go beyond locking your phone’s homescreen or apps.

CM Locker lets you apply a pattern lock, PIN/passcode, or lock and unlock your phone using your fingerprint (when your device supports a fingerprint sensor). It sports a massive collection of lock screen themes to customize your phone’s appearance. Alongside themes, the app is pre-loaded with many charming wallpapers for your Android. Themes and wallpapers can have their settings adjusted and be automatically swapped each day.

As this screen lock for Android mainly focuses on adding extra security to your phone, it can be set to take a picture with the selfie camera when pattern or password to unlock your phone is applied numerous times. It can make your phone take a selfie even with a wrong, incorrect code entry. You’ll always be seeing which of your friends is over-interested at accessing your privacy and also laugh at funny photos of you when you incorrectly swipe through the pattern unlock. Your birthday can be used to reset passcode or a new design in case you forget it.

There are shortcuts and toolbars that let you instantly swap through songs, open camera, enable flashlight, view recent apps and other recommended apps for Android, respond to social media messages without unlocking your phone, read the latest news online and offline, view your battery percentage, and if that’s not enough, see weather forecasts on your smartphone without unlocking it.

Go Locker


Go Locker is another alternative that provides you with a secure lock screen replacement. This app supports the gesture screen lock feature that lets you create your own unique way to lock your Android and quickly unlock it securely. You’ll have to create a geometrical figure by swiping your finger across your phone’s display. Just don’t create an over-complicated gesture that may be too difficult to be detected.

In addition to gesture locking, Go Locker, lets you lock and unlock your Android using a pattern, or PIN code. There’s an emergency screen unlocker that combines volume buttons or uses a pre-set password for you to unlock your smartphone’s screen when you forget the pattern or passcode. This feature should be enabled by checking in-app settings.

Go Locker themes and launchers can be found in the app’s theme store section. They usually are downloadable extensions that can be found on the Play Store.

Knock Lock’s most distinguishable feature is its classic Knock Lock screen locker that uses the combination of A, B, C, and D letters for creating a passcode.

The pro features will be available for 30 days.

The second locking type Knock Lock uses is called Time Lock. The way this works is by allowing you to select two numbers and the time when you want to have access to your phone. For example, if you chose the numbers 1 and 2 and at the moment you want to unlock your phone the time is 21:20, then your passcode is 122120. This is a great way to create a password that changes with time and the information to getting it right is known only by you. Probably the most innovative and smart way of adding extra security to the content on your smartphone.

The other two ways of locking and unlocking your Android phone with Knock Lock consist of passcode and pattern lock.

Knock Lock separates its features into two sections, in one side are placed the screenlock features and supports while on the other hand are the app lock features. You can move through them with a swipe. All four locking types are supported and you may have different lock types for each of them.
