Hi Oftkilted,
Thanks for the interest! I'd like to bring it to iOS, but I don't have ready access to an apple computer which would be necessary for compiling. It's kind of a catch-22 because there would be additional development time needed and financial costs for hosting on the iOS App Store ($100/year), but I haven't had enough traction on the Android app and Windows version yet to sustain that. Was thinking about maybe trying a small Kickstarter for the iOS version? I just am not sure if even that would be successful right now.
If you are interested in an iOS version, please take a minute to fill this quick form: https://forms.gle/Nx9hB8REEoYLChC2A and please help spread the word if you can. If I see enough demand for iOS, I will definitely try, and will be sure to update you!
