After entirely too many delays, the Pony Creator iOS app is available for purchase!
Get it here from the iTunes store!!!
(If you can't follow that link, it's easiest to find if you search for "pony creator" with the quotation marks. Without them it doesn't show up in the results yet. Or you can search for my full name to find my developer profile: Haley Reeve)
Like the Android version, it costs $0.99. The app currently has all the same content as v3 of the online game, but does not support fully customizable posing right now. However, I'm currently working with some artists to add new content like manes and accessories, plus new features like cutie marks and possibly having more than one pony on screen. All of these updates will be exclusive to the apps! If the app does well enough, I'll also do my best to add the customizable posing. (This is a difficult feature to implement on mobile devices, which is why I haven't been able to do it yet.)
In fact, the Android version recently got an update to allow the import and editing of custom cutie marks. I'm still working on the best way to incorporate this feature into the iOS version, but it will be available soon. Anything you can do to support me is greatly appreciated! Developing the app and hiring the artists costs money, so how much new content I can add will depend on how well the iOS version does.
Thank you all for your patience and your continued support.
ETA: If you do download the app and have any problems with it, feel free to contact me here! It's much easier to talk on dA than through the App Store reviews since we can do a proper back and forth.
