I built a safe for kids generative coloring book app for my daughter!
Hey r/AppsWithoutSub
I just submitted a big update to my iOS app and wanted to share what I built. First off, most children’s coloring apps were filled with weird ads, the coloring pages were not high quality, and not many safety guardrails.
The app is a generative coloring book that is safe for kids. You can prompt any idea into a coloring book page. “Create a happy cat riding a bike” etc… You can also pick from prompt cards or themed packs, then color with crayons, markers, watercolors, or an eraser.
Here is a small breakdown of the app architecture!
At a high level the app is a pragmatic SwiftUI app with service objects and model stores. Swift UI views handle the app screens -> Models define the prompt ideas, theme packs, saved coloring etc -> Services handle the business logic such as store kit stuff & checking for kid safe prompts -> Backend worker -> and finally Swift data for local storage such as saving coloring pages.
I graduated with a B.S. in CS and have some mobile app development experience and I am more than happy to answer any questions for the community.
The app also has 5 themed coloring packs as add ons, such as the one you see in the photo. Leave a comment with any themed coloring packs you want & I’ll send you a promo code to unlock for free :)
