Top 5 Best app locks for Android

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 they open the messaging app and read personal messages.

Consider the following two situations:

  1. 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.
  2. 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 the best app lock for Android.

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.
