Apparently so. The app has attracted around <a href="https://sec.report/Document/0001628280-21-016861/" target="_blank">38 million monthly active users</a>, according to the company, and not all of them sign up for trivial reasons.

Now the company is expanding beyond languages: <a href="https://www.duolingo.com/abc" target="_blank">Duolingo ABC</a>, which teaches kids to read, just launched, and <a href="https://techcrunch.com/2021/08/05/duolingo-is-working-on-a-math-app-for-kids/" target="_blank">a math class for kids</a> is in development.</div></td></tr><tr><td align="left" style="font-size:0px;padding:10px 0;word-break:break-word;"><div style="font-family:Helvetica Neue, Helvetica, Arial, YuGothic, Hiragino Kaku Gothic ProN, Hiragino Sans, Meiryo, MS Gothic, sans-serif;font-size:19px;line-height:27px;text-align:left;color:#000000;">Duolingo is also serious about staying relevant for the long haul. Following <a href="https://www.cnbc.com/2021/07/28/language-learning-app-duolingo-pops-35percent-in-public-debut-on-the-nasdaq.html" target="_blank">an IPO</a> this summer, the firm is now worth more than <a href="https://finance.yahoo.com/quote/DUOL/" target="_blank">$6 billion</a>. Von Ahn says he wants to keep running the company the same way he did before it went public, by allowing employees to prioritize the educational experience and keeping the lessons free, no matter what pressures he faces every quarter. His staff, including engineers who he says turned down better paying jobs at Google or Microsoft because they believed in Duolingo’s mission, are counting on the leader to live up to that promise.</div></td></tr><tr><td style="font-size:0px;padding:20px 0;word-break:break-word;"><p style="border-top:solid 1px #D3D3D3;font-size:1;margin:0px auto;width:100%;"></p>

To protect its overseas staff, Von Ahn says, Duolingo keeps its curriculum respectful of local laws and cultures.
