Hi Razvan,
Thank you for your message.
Regarding your questions:
- Cubasis 2 is available for iPad only
- If you just purchased Cubasis 2 by accident, it might be worth a try to get in touch with Apple to ask them for a refund.
- Cubasis 3 is an universal app, which means you can run it both on the iPad and iPhone at the same time.
Hope that helps!
Best,
Lars
