I had to post something... It's been too long. THIS IS NOT A SCRATCH PROJECT (though I could make a scratch version...?)
Android is better than iPhone, Period. Yes, it's faster to code apps in Swift, and it will take you to 80% faster. Android just needs good knowledge of Java, and while development may be slower, it's way less of a pain once the app is out there. Plus the play store is like ten times easier to put an app on because it only takes hours before your app is out. For the App Store, do you really need 2 days? Yes, I get that Apple may be easier for some, but for me, I prefer Android. I may make an Apple version for this app sometime, but not anytime soon.
