10 Best App Lockers for Android You Can Use

Last Updated: February 20, 2017

A smartphone is a very personal gadget. We have personal messages and information in the likes of messaging & social media apps. Then there are banking apps, where a lot of our sensitive data is stored. Also, we click a ton of personal photos and videos, which are saved in the gallery app of our smartphone. Unlike iOS, where you need to be jailbroken to lock apps with Touch ID, Android features a number of cool apps that let you lock apps through a password, PIN, fingerprint scanner or some really unique ways.

While custom ROMs like CyanogenMod (read: Lineage OS) and Android builds from various manufacturers come with the app locking feature built-in, most Android users look for app lockers on the Google Play Store. So, if you are looking for app lockers on Android to lock apps with your device’s fingerprint sensor, we have you covered. Here are the 10 best app lockers for Android:

1. AppLock

AppLock is the most popular app locker app on the Play Store, with more than 100 million downloads. The app has certainly earned that, as it’s also the best app locker for Android. With AppLock, you can lock apps as well as various Android toggles like WiFi, Bluetooth, mobile data etc. You can even lock incoming calls or almost any Android element. You can also set up various lock profiles for work, home etc. There are also options to make sure that the app locking triggers at a certain time or location. AppLock also lets you add a cover like a warning message that says “the app has stopped”, which is one of the usual Android warnings.

Moreover, you can choose to hide the app, prevent uninstallation, and set up a delay for re-locking. It also includes a power saving mode, so if you use AppLock, you don’t need to worry about the app draining your device’s battery. Along with app locking, the app also brings a photo and video vault, and support for plugins. AppLock is certainly a feature rich app and it works flawlessly. The app does include ads but they are rare and of the non-intrusive kind.

2. Privacy Knight Applock

Privacy Knight, designed by the Alibaba group, is an ad-free and totally free app locker that isn’t very popular but certainly deserves to be.

Along with apps, you can lock incoming calls with Privacy Knight. There are options to prevent uninstallation of the app, hide notification preview from apps like WhatsApp and secret door to disguise the app as a dialer. Along with that, the app captures photos of intruders that enter the wrong password.

5. App Locker: Fingerprint & Pin

App Locker is one of the many app lockers for Android with the “app locker” moniker. The app isn’t very popular and it’s not hard to understand why. It has a pretty outdated UI but if you look past that, it has some really unique features. Apart from the usual app locking features, App Locker lets you set custom lock settings on a per app basis. So, you can set the primary lock method for an app to fingerprint, while pattern as the primary method for another app. Other than that, the app lets you choose a crash cover, set app re-lock delay and more. It includes ads but you can remove the ads by purchasing the full version of the app.

The Keepsafe App Lock app is the simplest app locker in this list. The app features a gorgeous Material Design UI and packs in support for PIN, pattern and fingerprints. There are options to set delay on when the apps are re-locked, prevent uninstall and hide PIN touches. If you’d like to disable the app temporarily, the app lets you disable it for a few hours. The app is available in a free version but it features ads, however, you can make an in-app purchase to remove ads in the app. That pretty much sums up the app, I have used the app for quite a while and it’s as simple as it gets and works well.

The app is available in a free version but it’s fairly limited. However, you can get the Premium version, which brings more theming options, like the ability to change background of the lock page. It also brings options to set safe locations, detect intruders, set up a fake crash, and more. Overall, the app definitely packs in a ton of features but in my usage, I did face a few hiccups in performance, so that’s something you should keep in mind.

8. AppLock – Fingerprint

AppLock – Fingerprint (yes, that’s the app’s name on the Play Store) is another very popular app locker on Android and deservedly so, because it packs in a ton of great features. There’s support for fingerprint scanner, PIN, and you can set different passwords for different apps. You can also set up profiles and make sure that the app locks activate at a certain time or based on the WiFi and Bluetooth connection. Along with apps, the app locker also lets you lock system settings, the home screen, rotation, and more.

10. CM AppLock

Cheetah Mobile, the developers behind the CM AppLock app, does not have a great reputation, all thanks to overwhelming app recommendations in their various apps. Having said that, the CM AppLock is still decent app locker you can use. The app supports fingerprint unlocking and lets you lock apps and settings like WiFi, Bluetooth etc. It also lets you set a delay in re-locking apps and brings the ability to capture a selfie of any intruder when 3 incorrect attempts are made.
