AirParrot 2 is an entirely separate product. It’s got a ton of new features, including Chromecast support, multi-device mirroring and audio only mirroring. AirParrot 2 is much more than just a software update. It’s an entirely new application.
We supported the original release of AirParrot for nearly three years, and we haven’t charged users for updates that included features or new functions. Over the last few months, we poured a ton of time into AirParrot 2, and because of this, the upgrade to AirParrot 2 is not free. The price is $12.99 for a single seat license.
