Want to lock WhatsApp, photos, messages or other private apps on your Android phone? AppLock by DoMobile is designed to add an extra layer of protection by requiring a password, PIN, pattern or other supported security method before selected apps can be opened.
If you are searching for an AppLock, app lock for Android, WhatsApp lock, photo lock or privacy protection app, this is a useful option to consider.
What Is AppLock?
AppLock lets you select individual apps and protect them from unauthorized access. Instead of locking the entire phone, you can choose specific applications that contain personal information.
This can be useful for protecting WhatsApp chats, Gallery, Photos, Messages, social media apps and other private applications when someone else is using your phone.
Testing Setup & Our Experience
We tested AppLock on a Samsung Galaxy A55 5G running Android 15, focusing on locking applications, unlocking them and checking the available privacy features.
After installing the app, we created a security method and selected WhatsApp and Gallery as test applications. We then closed and reopened them to check whether AppLock requested authentication before allowing access.
We also explored the settings to check how easily locked applications could be changed.
The basic setup was straightforward. However, users should carefully review the permissions requested by any third-party security application before enabling its protection features.

Is AppLock Worth Downloading?
If you are searching for an app lock for Android, WhatsApp lock app, photo lock app, privacy app or application password lock, AppLock is worth trying.
Its biggest advantage is selective protection. You do not have to lock every application on your phone. You can simply choose the apps containing information you want to keep private.
This can be particularly useful when sharing your phone with family members, children or friends, or when you want an additional security layer for messaging, photos and social-media applications.
However, an app-level lock should not be considered a replacement for your phone’s main screen lock. For stronger protection, use a secure device PIN or password as your primary security method.
