Are you sure? It's not described that way. This is their description:
With Evernote Basic, you can use the Evernote app on up to two devices. This device limit applies to the following Evernote apps:
Evernote for Mac
Evernote for Windows
Evernote for iOS
Evernote for Android
Evernote Web
...
Each device where you’re signed in to the Evernote app counts toward your device limit.
If you have multiple devices of the same type, each one counts toward your device limit. For example, if you sign in to your Evernote account on two different iPhones, it’s counted as two devices.
