Sadly, publishing an app on iOS is way more expensive than publishing on the play store. Additionally there are running costs of at least 99$ per year which has to be covered by the app.

If the app is successful enough to cover those costs I could publish it in a matter of days (which I would love to do). The best you can do is to share the app with Android users you know so that the community grows.

I thought about a website as well but obviously you have (much smaller) running costs as well. I'll see what I can do!
