Stop others to Launch, Run Apps on Your Android Phone and Tablet

A few weeks ago, I wrote a post on how to hide apps on your Android device. However, some people might just prefer to password protect apps on their Android device, instead of hiding them.

There are quite a few apps in the Play Store that let users achieve t. One such app is APP Lock, which allows users to lock apps on their Android device using a password, PIN or even a pattern.

How To Lock An App On Your Android Devices

Step 1: Download APP Lock from the Play Store.


Step 2: When you start the app for the first time, it will ask you to set the password to lock the apps. Once the password has been entered, the app will require users to enter a security question, along with its answer and an optional hint in cases of emergency where the user might have forgotten the password.


Step 3: App Lock will now show a list of all the apps installed on your phone. Users can then simply flip the lock switch near the name of an app to lock it. App Lock also allows users to lock certain phone functionalities including the ability to install/uninstall an app from the Play Store or from your device, or even receiving an incoming call.

Once you have selected all the apps you want to lock, just exit the app. Next time, when you start App Lock or any other app that you have locked, you will be prompted for the password.



APP Lock has certain advanced options hidden under the Settings menu, which might be useful for quite a few people. APP Lock can prompt for a password every time the phone’s screen is turned off while using any of the locked apps.

Alternatively, users can also set a short ‘exit’ time during during which the app will not ask for a password.The best part about APP Lock is that it is completely free without any ads. While the UI of the app could be better, it is more than enough to get the job done.

Vision App Lock is another alternative to APP Lock that allows users to unlock apps on their device using face recognition along with the usual pattern and PIN. The app does require a decent front camera on your device with proper lighting condition, which does not really make it practical for day-to-day usage.
