As of now, we have no plans to make a Windows version of iReal Pro.

There is an easy way to run the Android version on a PC using emulators like Memu.
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.
(Slow or older PCs will probably not run emulation software very well.)

Many of our Windows users are using BlueStacks with good results.
