Mathy: Learn math automaticity through interactive games on iOS and web.

What it does

Mathy is a mobile and web app designed to help users build automaticity in math through interactive games and drills. The core concept treats math facts and concepts as skills to be automated rather than learned once. As topics become automatic, the app spaces out practice sessions—they can stretch weeks or longer—reducing the need for frequent review.

Who it is for

Mathy targets math learners who want a mobile-friendly alternative to flashcard systems like Anki. The founder positions it as a complement to structured math courses like Math Academy, intended for people who study math seriously but need a convenient way to drill weak areas during spare moments. It appeals to learners balancing math study with other commitments and looking for a less cumbersome drilling tool.

Pricing

The site does not show prices. The creator describes Mathy as free with no account required to use it on iOS or web.

How it stands out

Mathy's counterintuitive design philosophy—that successful drilling results in less frequent usage—differentiates it from most learning tools that encourage constant engagement. The app tracks weak areas and adapts practice session frequency based on automaticity gains. Unlike general flashcard tools, it is purpose-built for math, avoiding the friction of creating and maintaining custom cards. The founder developed it after experimenting with existing tools and finding no satisfactory math-specific alternative.

What a founder should check

A potential competitor should verify whether Anki or similar general flashcard platforms will remain sufficient for most users, making a specialized math app unnecessary. They should assess switching costs—whether users currently embedded in Anki or other systems would migrate, and whether the free model creates a viable path to revenue. Finally, they should investigate the durability of Mathy's core advantage: whether the spacing algorithm and math-specific interface create enough of a moat, or whether incumbents can quickly copy the concept if market demand emerges.
