    "This app is great for keeping your privacy. It keeps people from getting into your apps, like Whatsapp, with an extra password. Even takes a picture of the person with the selfie cam if they keep trying to get in! Great app!"

    "Private zone is the solution to lock apps such as whatsapp, facebook and others. It allows another layer of security, putting a password on apps you don't want people to open directly. It adds safety if your phone is every compromised, people won't be able to access your sensitive apps."

    "Worried about a possible password compromise? Use your finger to unlock any app you choose! This ensures peace of mind that unauthorized access of your most sensitive information never happens. Using software and security measures intended for prevention of data theft, AppLock is perfect for those who want their data secured all day and night."

    "I absolutely love Fingerprint Login. I no longer have to worry about someone else gaining access to my phone and getting into my personal things/information. With this app, all of my other apps are secure and only my fingerprint will get them open. Now that is comfort."

    "I don't suspect someone is snooping on me, but I've heard horror stories to not protect my stuff. This app is perfect for locking down your apps so no one can see your content, or post stuff under your name. Like I said, I'm not really that concerned, but I know I'd be if someone started snooping through my files, or started posting prank status updates."

    "Chatlock is a simple and effective application you can use for your mobile device. I love this service! The fact that it is free to download is a huge perk to me. It's 4 star rating and 175,000+ downloads gives me confidence that the app meets it's claims. It works by allowing you to assign pin number protected access to social media and messaging applications. I've had my facebook account accessed without my permission when my phone was stolen. Embarrassing and malicious information was posted by someone else pretending to be me. It was a very damaging experience. I had friends and relatives angry and worried about my mental well being. It took a long time to put out all of the fires this caused in my social circle. This application would have prevented this disaster. It let's me choose which social media messaging apps I want to protect. Then it's a simple process of assigning a pin number to my protected apps. It will also take a picture of anyone attempting to access your phone with the front facing camera!!! I love Chatlock and the added protection it provides gives me the security I need. It makes me feel more comfortable and confident to leave my phone out and let others use it. Download this APP!"

    "***** I absolutely love this app! First, your password can be your fingerprint - how easy is that. Second, I have two young children who constantly get on my phone and have played games where they can purchase extra coins, bids, etc. Now the poor little things are unable to access my phone - waaah! Seriously, you need to get this app. It's the best on the market with between 5,000,000 - 10,000,000 downloads!"

    "I'd just transferred some "found" money into 15 different off shore bank accounts and now I needed a secure way to store the account numbers and passwords. So I put them in a text file on my iPhone. Then I downloaded and installed AppLock to keep anyone from opening Notes. Used the fingerprint verification protocol to protect them. CAN NOT ACCESS NOTES NOW!! PLEASE HELP. URGENT!! ps. Would not recommend."

    "Hexlock App Lock and Photo Vault is perfect for a Whatsapp lock. I am able to keep my messages safe with an easy setup, and only locking whatever app I want instead of the entire phone.

    "With the help of this app, you can easily secure your private and group WhatsApp chat(s) and maintain their privacy using a PIN. The best part is, it can not only lock chats, but it even has the ability to secure the complete app using a single PIN. With these features Locker for Whatsapp, is a robust privacy app for your Android device or smartphone. Moreover, in case you forget your 4-digit PIN you can easily retrieve your login details through your recovery email address."

    "With lockIO you can lock apps as every other app locker, hide photos or videos in a vault but most importantly you can protect a basic setting when a thief steals any device: power off your phone. lockIO is the ONLY app locker that incorporates this Power Lock feature, making it unique among app lockers. By securing the power off process with a password request, only owners can de-activate their phones, and thus thieves will have to switch strategies when stealing a power-locked phone."
