Hi Steve,
Thanks for contacting us.
Do you mean to the latest version of djay 1 or djay 2?
You can get the latest version of djay 1 (1.6.6) for free. Since the app is no longer available for sale, though, you need to delete your current djay app first. Please try the following:
- Open the App Store app on your iPad and go to “Purchases”
- Verify that you can find djay 1 there
- Then delete your current djay app
- Go back to App Store > Purchases and download djay again
The upgrade to djay 2 is not for free though. You can buy djay 2 in the App Store. Please note that djay 2 requires iOS 7.
