About MangoBubbles
Two sisters. Three apps. One big dream.
MangoBubbles is a company started by two sisters who love building apps. We think kids can make awesome things — and we're proving it! All of our apps are on the Apple App Store and completely free for everyone to download and enjoy.
We started MangoBubbles because we wanted to turn our favorite hobbies into apps that other people could use too. Whether it's tracking books, practicing scripts, or learning about animals, we hope our apps bring a little fun to your day!
Meet the Founders
Della Koch
Age 10
Apps: Mango Bookshelf & MangoScript
Della loves reading and theater — two things that inspired her to build her apps. With Mango Bookshelf, she created a way to track all the books you read and see how much time you spend reading. And with MangoScript, she built an app that helps actors practice their scripts by reading scene partner lines out loud.
When Della isn't coding, you can probably find her with her nose in a book or rehearsing for a play!
Mira Koch
Age 8
App: BubbleAnimals
Mira loves animals — all kinds! That's exactly why she built BubbleAnimals, an app packed with fun facts, beautiful photos, and cool details about animals from all over the world. Did you know a shrimp's heart is in its head? You'll learn stuff like that in her app!
When Mira isn't building apps, she's probably playing with her pets or learning about a new animal species.
