By default, both Android phones and iPhones come with built-in options to lock apps. But if you are like me and want more privacy & security features, such as fingerprint unlock, intruder selfies, fake lock screens, or hiding entire apps, this guide is for you. I have handpicked and mentioned some of the best app lockers in this article. I personally tested and used these apps to highlight what makes each one stand out. You can review these lists and choose the best one to protect your desired apps.
Applock Pro
If you are like me, who stores everything, from private messages to personal photos on your phone, then you should definitely try the “AppLock Pro – App Lock & Guard”. It is one of the best I have used on my Android device. The app is easy to set up and gives you different ways to lock your apps, including PIN, pattern, fingerprint, and even a cool KnockCode system. For those who love a bit of personalization, the app lets you customize lock screen themes and backgrounds, even using your own photos or default ones.
One of my favorite features of this app is the Spy Camera. AppLock Pro silently snaps a selfie using the front camera and saves it whenever someone enters the wrong password. So you know exactly who tried to access the app or your phone. There’s also a Spy Alarm on this app that triggers a loud alert after five incorrect attempts. You can even enable a Fake Error Message feature that makes the app look like it has crashed instead of being locked. This feature adds a security layer of protection. AppLock Pro is a powerful app locker that delivers smart features, runs smoothly, doesn’t drain your battery, and offers an ad-free version at a reasonable price.

If you’re looking for a secure way to keep your private photos and videos out of sight, AppLock – Photo Lock is worth trying out. With over 400 million users worldwide, it is one of the most trusted tools for media privacy on your iPhone. Whether it is sensitive images, personal clips, or memories, AppLock helps you hide them all behind a password, fingerprint, or Face ID. Once your media is locked inside the app, it is completely inaccessible without the right credentials.
I like how AppLock handles everyday privacy problems, like kids deleting photos, friends snooping, or risks during phone repairs. It allows you to store unlimited albums, set custom covers, and is easy to use. Another feature is the Private Browser. It automatically clears the browsing history, so you can search without worrying about leaving a digital trace. Whether you want to lock down memories, confidential media, or keep things organized, AppLock – Photo Lock is the best for your iPhone and iPad devices.
App Lock, Hide App & Lock Apps
App Lock, Hide App & Lock Apps is a great all-in-one privacy tool if you want to go beyond just locking apps. What sets this app locker apart is its ability to hide entire apps, so no one even knows the apps are installed on your phone. This app locker is perfect for keeping things secret and adding more security to your data. You can easily lock photos, videos, and sensitive apps, and the app has a Secret Password Manager to safely store things like bank info, contacts, or private notes.
The app also generates strong random passwords and includes clear step-by-step instructions to help you get set up quickly. Whether you are trying to protect your data or just want to keep certain apps and files out of sight, App Lock, Hide App, and Lock Apps is the best app locker to use on your iOS devices.
AppLock – Fingerprint
AppLock – Fingerprint is one of the best app lockers for Android devices. It is a powerful app that performs beyond basic locking. Whether you want to secure social media apps like Facebook, Instagram, or TikTok, or protect your gallery and messages, this app offers strong protection using PIN, pattern, fingerprint, or even face recognition. What I find helpful on this app is the Intruder Catch feature, which snaps a photo or video of anyone trying to access your apps and sends the notification to your email. You can also use a Fake Lock screen that shows a fake error message instead of showing that the app is locked.
This app comes loaded with smart features like notification blocking, home screen lock, custom passwords for each app, and even auto-unlock when connected to trusted Wi-Fi or Bluetooth. It also supports a scalable pattern lock. Despite all these advanced options, the app is surprisingly lightweight and runs smoothly. If you are looking for a deeply customizable app locker, AppLock – Fingerprint is one of the best choices out there.
AppLock Master
AppLock Master is a highly customizable app locker that offers advanced security. You can lock apps through PIN, pattern, or fingerprint. One of the best features I like on this app is the temporary unlock option. It means that you don’t have to re-enter your password every time. It also lets you disguise the lock screen with fake crash messages or fingerprint scanners.
Apart from the app locking, you can secure incoming calls, recent tasks, and settings like Wi-Fi and Bluetooth toggles. The intruder selfie feature snaps a photo of anyone who tries to break in. AppLock Master offers custom themes, animated lock screen transitions, and the option to use your own background from the gallery. With features like icon hiding, orientation lock, and a user-friendly interface, AppLock Master delivers high protection.
