A smartphone is a very personal gadget. We have personal messages and information in the 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.
And such sensitive data needs to be protected from prying eyes.
So how can we protect this data? Here is the Solution.
Android features a number of cool apps that let you lock apps through a password, PIN, fingerprint scanner or some really unique ways.
Some devices come with built-in app locker, but those whose device don’t have a default applocker they don’t need to worry.
Here in this article we have curated 25 Best App lockers that you can safely use in 2021.
Most of these apps are available on Google Play Store. Hence you can trust them and install on your device.
So let’s get in to the topic.
Chances are, you have heard of Norton, the popular anti-virus maker. Well, the company offers a pretty good app locker for Android.
The Norton App Lock is a very simple app locker which should be a good choice, if you are looking for a free & ad-free app locker that just works. With Norton App Lock, you can lock apps by fingerprint, PIN or pattern.
There aren’t a lot of options here but you can protect it from uninstallation by giving it admin privileges. There are also options to set a recovery email, along with a sneak peak feature that captures photos of intruders who enter the wrong PIN or pattern 3 times.
Wrapping our list is FingerSecurity, an Android app lock that is regarded as one of the top contenders among its type of service.
This app has a wide range of features that will otherwise not compromise the data on the phone. It also boasts an advanced feature that prevents unauthorized behaviors like installing apps.
The extent of our negative review for this app is on its scope; the free version is very limited forcing anyone to purchase the premium version for a very cheap price.
Privacy Knight is of one the best app lock for Android that covers some excellent features to secure your apps. It is ad-free and does not contain any in-app purchases.
The app gives you different methods to lock your apps.
You can use a PIN/pattern, fingerprint scanner, face tracking, or a Disguise cover, such as to blow, shake, or use a crash message to unlock.
You can hide private photos and videos, prevent uninstallation of the apps, hide notification previews from apps, etc.
It can also capture a picture of anyone who types the wrong password. Although not as popular as other app locks for Android, it has almost all the essential features.
Apex Launcher is an excellent launcher and it just so happens to have an applock function.
The launcher features are pretty good and include various customizations, icon pack support, various effects, and you can hide elements like the status bar or the dock if you want them invisible.
There are also some app security features as well, including the ability to hide apps from the app drawer and an applock function with a password protect layer for extra security.
It’s always a little better if it’s baked into the launcher than from a dedicated app, so if you don’t mind re-doing your home screens, this one and Smart Launcher 5 (listed below) are good alternatives to dedicated applock apps.
Smart Launcher has long been a favorite for the best Android launcher, with its simple “flower” favorites grid and sorted app folder.
The latest version, Smart Launcher 5, adds a ton of features and refinements.
Smart Launcher’s flower grid is still available, but it’s joined by a number of other well thought-out layouts designed to keep your favorite apps within easy reach of one hand, while smart search and an intelligently sorted and customizable app drawer makes it easy to find whatever you need, whether on your phone or out in the web.
Adaptive icons and colors, fully resizable widgets, and more customizations round out the package, making for a great update to a classic launcher.
You’ll need to shell out $7 for the Pro version of Smart Launcher to access the many of those extra features, including pop-up widgets and expanded gesture controls.
MaxLock is an awesome app locker for rooted Android devices only. That’s sad but if you have a rooted Android device, you get some great features with MaxLock.
The app is based on Xposed Framework, so you obviously need to have Xposed installed on your device. MaxLock is a totally free and ad-free app that unlike many app lockers out there, gives performance and battery the priority.
The locking methods include fingerprint, PIN, pattern and knock code. The open-source app includes ton of customization options, fake crash feature, a MasterSwitch to disable it easily, ability to remove thumbnail of apps in the recents window, and more.

However, the free version covers all the necessary features, and the number of ads in the app is very less.
Perfect AppLock is another one of the better applocks out there.
It features the basics, including support for locking up WiFi, Bluetooth, and other toggles. It’s also rather frustrating to get passed.
It throws fake errors and all kinds of other messages out there. That makes people think there’s a different issue other than an applock. The free and paid versions provide the exact same features.
The only difference is that the paid version doesn’t have advertising. It’s a solid all around option, even if it’s name kind of oversells its capabilities a little bit.
Ultra AppLock is a decent Android app lock that lets you do the basics. The app requires users to provide a password or a fingerprint biometric to access the app or files that have been locked.
It will send the owner of the phone a break-in alert if anyone tries to gain access and provided the wrong password. It comes with a built-in cleaner and battery saver features that would sometimes fail to work.
Ultra AppLock works seamlessly and will continue to do so as long as you veer away from trying to access the cleaner feature.

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.

15. App Lock (by Lucky Mobile Apps)
This app’s claim to fame is what separates it from others; it boasts that it can lock apps and keep unauthorized access at bay with a ‘secure’ but ‘easy to unlock’ pattern.

17. Smart AppLock (by ThinkYeah Mobile)
Smart AppLock is my second pick in this list for the best app locker for Android and there are two primary reasons for that. Firstly, it’s very lightweight and does not bring any kind of ads whatsoever.
Not on the lock screen or inside the app. Secondly, the app is fully updated and compatible with on-screen fingerprint sensors.
It basically means that the developer behind the app updates the app regularly to make it compliant with the newer Android APIs and devices.
If you are wondering if this app locker blurs the app preview in the recent menu then sadly, it doesn’t do that due to system restrictions and that is acceptable. As for the app, it’s fairly clean and does not bring any bloatware.
You can set a screen lock pattern or simply use your native fingerprint sensor that is already stored on your smartphone. Having said that, I did notice a persistent notification on the top, but you can disable it in one tap so that’s fine.

While you have all the standard app locker features like PIN, Fingerprint and Pattern protection, it also brings photo vault, intruder selfie to catch people who are trying to break in and message security for hiding chat notifications from sensitive apps.
And that is not all, it also has a privacy browser but I would not really recommend using it.

For example, you can unlock all the social apps in one tap once you are at home– no more fiddling with lock permissions of each and every app.
Other than that, you can set the apps as an Administrator too so that no one can uninstall it. However, I would not really recommend that as it’s a system-level privilege.
