Duolingo has risen to prominence over the past decade with its language learning app offering people around the world a low-cost or free option to learn dozens of languages. With a reported 500 million users as of 2022, the app has found a loyal base among aspiring linguists. Now, the East Liberty-headquartered Duolingo has decided it’s time to branch out and use its expertise to tackle a universal struggle: math homework.
The forthcoming Duolingo Math platform will have two options. If you have a child between the ages of 7 and 12, then you can practice their multiplication and fractions in a game-like fashion. But, if youโve got a student at home over 13 who needs to work on their mental math โ or you want to practice math basics yourself โ then Duolingo Math is offering โbrain trainingโ to help users improve and apply math to their everyday lives.
The idea, Senior Software Engineer Sammi Siegel told Technical.ly, is to expand on Duolingoโs mission to make education accessible, and to make math a little more fun.
โAs a company weโve learned a lot over the last 10 years about teaching on mobile platforms, from game mechanics like experience points to developing interactive lessons to increase learning, all things which are transferable to other subjects,โ Siegel said. โWe want to make learning math more accessible and fun, just like weโve done for language learning.โ

The development team included Siegel and two other engineers and at one point the team was even able to use Siegel’s coworkerโs daughter as a source of feedback. The public got a preview of Duolingo Math last August during Duocon, the free, virtual, pre-recorded conference providing updates on the companyโs business strategy and product features. Duocon 2022 is being held today.
Why a math app now? In the wake of learning loss due to the pandemic and pre-existing math anxiety amongst most Americans, Duolingo felt now was the perfect time to address the current need for supplemental math instruction, per the company. Because Duolingo wanted to ensure the lessons were relevant, the team included a math learning scientist whose job it was to provide insight on what kids would be most likely to learn and the best way to teach the subject.
โOur goal to be an educational app that teaches in a fun, gamified way is the same,โ Siegel said. โThe math exercises are still as interactive (and depending on the concepts being taught, even more so!) as the language app.โ

Siegel added that although math was a favorite subject for her while growing up, sheโs not unfamiliar with what itโs like to struggle with it. As the only woman in higher-level math courses throughout her education, sometimes she also found herself feeling downright isolated, she said. Without the support of her math professor father, Siegel recalled that she might have given up on the subject entirely. Still, sheโs aware that not every struggling student has a mathematician in their living room to use as a resource so she hopes the app can provide some relief.
โWe want to make learning math more accessible and fun, just like weโve done for language learning,โ Siegel said.
Duolingo Mathโs tech stack is made up of โprimarily Swift and some SwiftUI,โ the engineer said. “From a technical perspective, much of the underlying user interface code in the Math app is the same as the original Duolingo language app.”
The app will be available in beta testing on iOS devices and has already gained a waiting list amid plans to launch later this year. Sign up to join it here.
