Why do I need to pay for Nebo in each store?
Nebo is available on Windows, iOS, and Android platforms, but these platforms will require you to purchase Nebo from their own respective app stores for use on the devices that run on their individual operating systems.
If you buy Nebo in the App Store (iOS), you can't download it for free on your Android device or your Windows device, and vice versa. This is something over which MyScript has no control, as you can understand Apple, Google and Microsoft are different companies and they don't share the licences between the stores.
Can I see my notes on different devices using Nebo?
If you have Nebo on different operating systems, i.e; iOS, Windows, and Android, you can manually sync your notes across the different devices, as long as you are signed into the same MyScript and cloud account on each of them. Read more about syncing here: Sync your notes
