Once you register, you will receive an email from Learnistic.com with instructions to download the app. You will also be registering with your cell phone # (since it’s a mobile app), and you’ll register with a 4 digit code instead of a password. If you would like to use the desktop version instead of the mobile app, you can do so at https://app.learnistic.com/apps. (you must still register with Learnistic first however)
