I built a free dragon math app for my daughter because every math app I found was broken in the same way

My daughter works harder than most adults I know.

She sits down, she tries, she puts in the time. And her math facts still wouldn't stick. So I did what any reasonable parent does first: I went looking for something that would help.

I downloaded a bunch of apps. Tried a few browser games. Watched her work through them.

They all had the same problem. Either the game was actually fun but had almost no real math in it, or it was basically a worksheet wearing a Halloween costume. Thin "game" mechanics wrapped around the same rote drilling that wasn't working in the first place.

Neither of these was helping my kid actually build fluency. They just made the next 20 minutes pass.

So I built something.

Why dragons?

My daughter is obsessed with dragons, and not in a casual way. She reads books about dragons (currently the Wings of Fire series), makes art about dragons, collects dragon figurines, and has dragon earrings. So when I sat down to think about what would actually make her want to practice, the answer was obvious.

Dragons. Lots of dragons.

Math Dragons is a collection of mini games built around a dragon theme, designed specifically to build math fact fluency. To help kids get fast and confident with the facts themselves. Addition, subtraction, multiplication. The stuff that has to become automatic before the harder math can land.

The build

It took a few weeks to go from idea to something she actually enjoyed playing. She has been my entire QA department and has put real effort into helping make it something delightful. I've had fun getting familiar with Flutter and learning something about building games along the way.

Where it is now

It's live on the Android closed testing track with just a few kids in so far. My daughter plays every day and I can see some of those math facts starting to stick. That's the only number I really care about. If the kid who inspired the whole thing is choosing to play it, something is working.

The honest part

It's early. There are rough edges I'm actively fixing. The content library is smaller than I want it to be and the games still need balance and polish work. I'm shipping updates constantly based on feedback from the families already testing.

On monetization: I genuinely don't know yet. Right now it's 100% free and my focus is entirely on making it actually useful for kids. Anyone who joins the testing track now gets lifetime free access whenever I do add a paid tier.

What I'm looking for

Testers. If you have a kid in elementary school who's working on math facts, I'd love to get them in. Sign up here: https://mathdragons.vercel.app/ with your Google account email and I'll send you an invite directly.

Honest feedback. What keeps kids coming back, what loses them, what parents actually notice. I want the real reactions, not the polite ones.

Happy to answer anything about the build, the design decisions, the "why free," or whatever's useful.
