Hey Alex, I bought the app a few years ago when I first found the website. Just opened it up for the first time in a while, and saw I can buy the course through the app. But wanted to let you know (in the low chance you aren't aware) that purchasing the course through the app is only $20 instead of $25.
Drop me an email and I'll sort it out manually - mostly it works but it's not great. The app ecosystem for this isn't worth the hassle any longer and I'll retire that app when I get the new version out.
