4.0.0
Hello everybody. This is a minor update to the previous version. We now allow all users to view the device library and basics sections without creating an account. Simply click "Skip Login" on the sign-in page.
If you want to use the favorites tab that allows you to make a custom quick-access library of certain devices, or to take and track quiz progress, you will be asked to sign in. This allows us to store the favorites and quiz progress if you ever reinstall or get a new device.
