Your parents, grandparents, siblings, cousins, and friends might be interested to know more about your personal life. They give excuses to put their hands on your phone/tablet. The first thing that such people do when they have access to your phone is that they open the messaging app and read personal messages. Consider the following two situations:
- You have installed a dating app (Ex. Tinder) and have exchanged hot messages with another user. If your parents come across these messages, they will cancel the internet connection. If the messages are inappropriate, you might lose your smartphone forever.
- One of your friends has sent a private picture on Snapchat or WhatsApp. One bad day, you forget to carry the mobile. Your mother knows the pattern lock/password. She unlocks the device and finds the shared image.
You can prevent the above things/incidents by installing one of the following best app lock for Android:
Best Android App Lockers – 2021 Edition
AppLock is one of my favorite Android utilities. I am using AL since 2015 and I can confirm that it works like a charm. I’m not the only fan of this application. AL is trusted by 100 million Android users. It runs on tablets, phones, and has a small size APK (2.5 MB). How to use this tool? On startup, this Android app locker prompts its user to draw an unlock pattern. Make sure that you keep the pattern different from the one you have set in Android settings. Once the user draws his desired pattern, AL requests him/her to enter a valid email address. The app will unlock other cool features once you verify your email ID.
After entering your email address, tap the save option. Now, you will see a small window that shows the features that the current version of AppLock offers. Click the OK button to dismiss the changelog window. Now, you can password protect your personal folders, gallery (pictures/videos), and apps with AL. Apart from ensuring that no one excluding you can open the protected apps, AppLock lets you:
- Block others from installing games and apps from the Google Play Store without your permission.

SAL is yet another popular app for locking folders, WhatsApp, images, Snapchat, videos, etc. It was earlier known as App Protect. Developers have changed the name for some unknown reason.

Enter this number in the text field and you will see the main interface of Smart App lock for Android.
On the UI, you will see a green color button with a plus sign icon and several tabs. Tap the button. Now, SAL will show a list of installed apps on your Android device. It will also display toggle buttons to enable/disable password protection. Use the toggle button to enable AppLock protection. By default, SAL hides selected apps.
