Review: AppCrypt as an app locker for Mac

The primary feature of AppCrypt is to lock apps on Mac. It allows you to easily lock individual apps, one by one or in bulk, using password-based encryption. In addition to reliably password protecting apps, it can also record the failed attempts to open locked apps, which lets you know who the intruder is.

Another great thing about AppCrypt is its Schedule feature, which enables you to lock apps during certain hours. Parents can use this tool to effortlessly put a time limit on apps for kids.

Below are the steps on how to lock apps on Mac using AppCrypt, which can shed light on how convenient the tool is.

Step 1. Download and install Cisdem AppCrypt on Mac. Open it. You will be asked to set a password. Enter a password and repeat the password to confirm it. Read the warning and click Submit.


It’s recommended to use a strong, hard-to-guess password.

Step 2. You won’t find this Mac app locker in the Dock. Instead, it will appear in the menu bar at the top of the screen. Click its icon in the menu bar and choose Open Main Window.


Step 3. Click Add App in the top left corner of the interface, which will bring up a new Finder window. From Applications, select an app, and click Add. Here I’d like to lock Notes on Mac, so I select the Notes app. To lock certain apps all at once, mass selects them all and click Add.


Now the Mac apps of your choice are locked with a password. Their icons will show up on the left sidebar of AppCrypt.

What will happen if someone tries to open a locked app? When one clicks a locked app to open it, the app won’t open, and a box will appear asking for a password.


If one enters the correct password, the app will open smoothly. If the password entered is wrong, it will continue to refuse to open. Meanwhile, AppCrypt will record the failed attempt with details like time and take a picture of the intruder. The photo in the screenshot below is blurred here for the sake of privacy.


What should I do if I don’t want AppCrypt to lock a Mac app anymore? It’s easy. Select the app on the sidebar and click Remove App.


To effectively password-protect apps on Mac, it’s recommended to enable Launch at system startup in Preferences. You easily disable it at any time if needed. To find Preferences, click the icon above Menu in the top right corner of the main windows.


If you want to lock apps during certain hours, the Schedule feature can help. In Preferences, go to the Schedule tab. On the left, you will find a list of the locked Mac apps, select the app of your choosing, and click Settings. In the new interface that appears, click the plus icon in the bottom left corner, select the times of the day and day of the week, and click OK.

Review: AppCrypt as a website blocker for Mac

You can also use Cisdem AppCrypt to block websites on iMac, MacBook Pro, MacBook Air, etc. As you may know, Mac has a built-in solution to block websites. However, with this solution, the blocking only applies to Safari. What if you use Google Chrome? AppCrypt can help. It lets you block access to specific websites on multiple web browsers. The above-mentioned Schedule is also available to the website-blocking feature.

It offers two modes: Blocklist and Allowlist. Blocklist is the default mode. When it is enabled, you can visit any website except the ones that have been added to the Blocklist. If you turn on the Allowlist mode, AppCrypt will block all websites except the few on the Allowlist.

Step 1. In the main window of AppCrypt, click the icon above WebBlock. Now you are under the WebBlock tab in the Preferences window.

If you want to allow access to certain websites and block all the rest, you can turn on Allowlist. Likewise, add websites to the list one by one.

Once a website is blocked, if you try to visit it, it won’t load. Instead, you will be presented with an image telling you that the site is blocked.


There are two ways to unblock. Click the AppCrypt icon in the top menu bar and select Disable WebBlock. It will disable the blocking temporarily. You can also remove the site from the Blocklist. From the list, select the specific site and click the minus icon.


If you need to set a time limit on a website, you can go to the Schedule tab in Preferences. On the left is the list of blocked websites and locked apps. Select a website, click the Settings button in the bottom right corner. Click the plus icon to create a schedule. It’s possible to create multiple schedules. To apply the schedule to all blocked websites, select the box next to Apply to All. Click OK.
