Windows 11:
adds the ability to run Android apps installed from the Amazon Appstore (this is the link to Microsoft's information, computer requirements, install instructions, further links.)
We have made some adjustments to the Android version of iReal Pro to better work on large screens, with physical keyboards and made it available at the Amazon Appstore (direct link to iReal Pro's page at their AppStore.)
Download the Amazon Appstore from the Microsoft Appstore, sign in or create your Amazon account, then search for iReal Pro or use this link.
Note: the Amazon Appstore is currently available in these countries via the Microsoft Store.
Previous purchase: if you have previously purchased iReal Pro from the Amazon Appstore (for your Fire tablet or another Windows 11 computer) no further purchase is required to install again.
Please contact Amazon if there are problems installing.
Amazon AppStore information (about, compatible devices, eligible countries, downloading apps, Windows 11, problems, support, errors, cache, etc.)
Microsoft is still refining their implementation of WSA supporting Android apps.

Import songs/playlists/backup on Windows:
You can import songs/playlists from the iReal Pro Forums.

The Amazon Appstore and the Google Play Store are separate companies, they do not transfer app purchases between each other.

Android emulator: (for example Windows 10)
The other option is to run the Android version on a PC using an Android emulator. We have users reporting good results with Memu, and BlueStacks; (others with LDPlayer 4 and Nox having no problems either).
We have a tutorial but unfortunately we do not offer support when you're running the app with a third party app since we don’t have control over the other party’s app (see our Additional information link below).
(You would install the Google Play Store into the emulator if not already there.)
If you have previously purchased iReal Pro from the Play Store, make sure you are signed in with the Google account you used for its previous purchase so you can install iReal Pro for free.
Slow or older PCs will probably not run emulation software very well.
