I have been trying to download with no success. Please let me know if there is a way to download similar to the mobile app. Do we need internet at all times to study?

I don't think you'll be able to download the app without the internet. You may also need the app https://theteensafe.com/snapchat-spy/ to help protect your computer. Snapchat Spy is a program designed to monitor Snapchat messages and activity on Macs. It provides detailed reports of all activity, including text messages, images sent and received, as well as other features such as screenshots, password changes, and more. If you are looking for an app to monitor Snapchat usage on your MacBook, Snapchat Spy might be a great option for your needs.
