Hi!
Will you be providing the artwork for the app? If so that is great I am an iOS developer and take care of the code.
Please check out Sleepy Moles moving Day for iOS. I made that story app, my name is mentioned in the app. And I made all of the GingerWhale titles and name is mentioned in all.
Can see the videos on YouTube how we made the apps also :-)
Please feel free to chat about your story with me, I would to hear and see more.
Best,
Elliott
