10 Best App Lockers for Android

10 Best App Lockers for Android You Can Use

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. 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.

Best App Lockers for Android in 2020

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. Smart AppLock

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. Simply put, if you want a simple and lightweight app locker for your Android smartphone, do take a look at Smart AppLock.

3. Norton App Lock

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.

Install: (Free)

4. App Lock by Smart Mobile

App Lock by Smart Mobile is a fairly new app locker in the Play Store but it has gained a lot of traction due to its clean interface and straightforward approach. Similar to other app lockers in the list, it lets you lock apps through fingerprint, PIN or pattern as you prefer. There is a unique feature as well called profiles which categorize the apps in general, sensitive, social and payments labels. You can, in fact, create your own profile and include apps of your choice. The benefit of profile is that you can enforce a set of rules in just one tap.

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. All in all, I can say that App Lock by Smart Mobile is a neat app locker and has good features to boot. You can certainly give it a try.

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.

Install: (Free, Pro $3.99)

6. Keepsafe App Lock

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.

Install: (Free, with in-app purchase of $1.99 to remove ads)

7. FingerSecurity

FingerSecurity is one of the best app lockers for Android, thanks to its sheer number of features. The feature-rich app lets you lock apps via fingerprint and you can enable the improved protection features to make sure that parts of the app and the app’s data isn’t visible in the recents screen. There’s also the advanced security option to prevent uninstalls. The app also lets you set a time out, which is the delay in re-locking apps, along with options to theme the fingerprint indicator, and more.

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.

Install: (Free, with in-app purchase of $1.99 for Premium)

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.

Moreover, there are cool features like the ability to hide the app, remotely unlock a phone via SMS, “Observer” which as the name suggests captures photos on failed unlock attempts. AppLock – Fingerprint includes ads but you can remove them through an in-app purchase. Overall, it is the app to get if you love playing with a ton of options.

Install: (Free, with in-app purchases)

9. MaxLock

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.

There’s a Premium version of the app as well, which you can get via a donation. It brings features like I.Mod (grace period for delay in re-locking), logs of failed unlock attempts, and ability to backup/restore locked apps list.

Install: (Free, with donation for Premium features)

10. AppLock – Fingerprint & Password

App Lock by SailingLab is one of those app lockers that has a multitude of features apart from protecting apps from unauthorized users. 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.

From the face of it, AppLock is a feature-packed app locker and does a good job of protecting your chats and sensitive apps from prying eyes. Not to mention, there are themes as well for lock screen so there is that. However, you would encounter some ads on the lock screen and that gets annoying sometimes. Simply put, if you are looking for a complete solution that can lock your apps and also hide photos and videos on your Android device then App Lock by Sailing Lab can be a decent pick.

Lock Your Personal Apps with the Best App Lockers for Android

There are a ton of app locker apps on the Play Store but the aforementioned 10 are most certainly the best app lockers you can use on Android. All of them support the fingerprint scanner and all of them bring some unique features, so you can choose the app that suits you best. So, try out these app lockers on your Android smartphone and do let us know your thoughts in the comments section below.


  1. When it comes to security, worse than having none is having a false sense of being secure.

    “AppLock – Fingerprint” is a clear example of the latter. While the app has many interesting and useful characteristics, unfortunately it is a very weak app, and no, one does not need to be a hacker to overcome it, one only needs to kill all tasks to then gain access to all the “protected” apps. While it includes a “helper” that is supposed to fix this issue, once the task is killed it may take a minute or more before the app is restarted and begins to protect everything again… more than enough time for anyone to access the apps.

  2. I have used the number 1 for a very long time and I used to like it but now it will unlock the play store every time it updates itself which is very annoying. I don’t know if that’s something new android decided to add later on or if the phone I use now is not compatible with it but I need to keep it locked all the time. I think i will try these but I kind of doubt that they will work.

  6. Thanks a lot. Especially for the AppLock. I used it once and have been looking for it but I couldn’t remember the name. It is one of the most secure locker I have used so far. Thanks for reminding the name.

  7. 6 keep safe AppLock

  9. The only app locker that really helps users to secure their phone is lockIO… it ask for a password to switch off your phone!

  10. Hi,

    I only use Huawei phones/tablets and only some of the app lock apps work with Huawei’s phone manager, especially its “block apps from running in the background” feature.

    The only App Lock apps working on Huawei I found so far are Smart App Lock by SpSoft and Privacy Knight by Taobao.

    Here’s my experiences (especially with using Huawei’s App Lock alongside with an extra App Lock app):

    Smart App Lock

    Only works fine (on Huawei G8, Android 6.0.1, EMUI 4.0 3) as long as you do not(!) install the Helper app that’s supposed to prevent it from being force stopped and you allow it to run in the background with Huawei’s phone manager! If the helper app is installed you can force stop Smart App Lock and it wont restart after a reboot or through its internal restart schedule. But: Without the helper app you can even use it alongside Huawei’s own phone manager app lock for locking critical apps with two different PINs or with fingerprint plus PIN!

    Privacy Knight

    If you don’t allow the app to run in the background (Huawei G8, Android 6.0.1, EMUI 4.0.3), it sometimes works and sometimes it just starts up locked apps without asking for the code… Behaviour like that is dangerous for a security app. But at least it works fine once you allow it to run in the background – just lock Huawei’s phone manager that controls permissions to run in the background and you’re fine. Unfortunately you cannot use the Huawei phone manager’s app lock alongside Privacy Knight since they both “battle” for being on top for entering the PIN or using the fingerprint.

    So: An extra App Lock app alongside with Huawei’s app lock only works with Smart App Lock from SpSoft (for me and so far). Using a second App Lock app you can enable basic security with quick fingerprint unlock via Huawei’s phone manager and add extra security to critical apps with a longer PIN via Smart App Lock. Snart App lock will always cover the “use fingerprint screen” but apps you only fingerprint locked with Huawei’s app lock, can still be unlocked just with a fingerprint. On the other hand – even if you enter Smart App Lock’s PIN when requested, the Huawei app lock fingerprint will still be required by those apps. This is like an undocumented stealth feature!

  11. Are these apps safe enough to protect data such as photos , videos….
    I found some reviews that says applock misuses our data…

  12. I want my child to have talk/text only. I can turn off mobile data through the provider (TMobile) and turn off wifi in settings, so I just need something to block settings so she can’t turn on wifi. Is there any way she could work around that to get online?
    Also, I think sending pix and group texts would be ok, but are either of those even possible if data and wifi are disabled?
