About App Locker
We all hand our phones to others — to show a photo, make a call, or let a child play a game. App Locker makes sure that gesture never turns into snooping. Lock any app on your phone behind a PIN: WhatsApp chats, your gallery, messages, banking apps, social media — anything you choose. Locked apps ask for the PIN every time they are opened, and the locker re-locks automatically when you leave. It is lightweight, fast, and works quietly in the background, giving you total control over who sees what on your phone.
Beyond basic locking, App Locker is designed for real-life situations Pakistani users face every day: handing the phone to a shopkeeper to show a receipt, letting children play games, or sharing the phone with family members. Because the lock screen appears instantly and the app re-locks on exit, there is no awkward moment where someone sees something private. The PIN recovery through Gmail means even if you forget your code, you are never permanently locked out — a thoughtful safety net that many locker apps simply do not offer.

Pro Tips
💡 Lock newly installed apps immediately
Whenever you install a banking, wallet or messaging app, open App Locker first and add it to the protected list before you even log in. This way your accounts are guarded from the very first use.
💡 Use a PIN you do not use elsewhere
Pick a code that is different from your phone unlock PIN and ATM PIN. If someone watches you unlock your phone, your locked apps still stay safe.
💡 Enable intruder alerts
Turn on wrong-PIN alerts in settings. If a curious friend or a child tries to guess your code, you will know about it the next time you open the app.

- Tap Install and wait a few seconds while App Locker installs.
- Tap Open to launch the app. If the app asks for permissions (storage, notifications, etc.), allow only what you need for the features you will use.
- To update later, download the newer version from this page and install it over the old one — your data stays safe.
