Scrivener on other iOS items

I bought Scrivener on my ipad in Feb.2018, before I got my MacBook Air. I’ve had no trouble of getting it onto my phone and iPad, however I can not get it to download on to my MacBook Air. When going to the app store it prompts me to buy it again, I do not want to spend another $50 on the program I already have on my other two apple items. Can anyone help me get it onto my primary writing tool?

Thanks,
Amy

Scrivener for iOS and Mac (and Windows) are all different products, requiring purchase of separate licenses.

I’ll think you’ll find the Mac version has significantly more functionality than on iOS. You can download a free 30 day trial from this site to evaluate it and see for yourself.
