For its birthday, Duolingo is finally giving learners what they asked for

Language learning platform Duolingo is giving learners who have lost their streaks a chance to reclaim them through a limited-time global initiative tied to the birthday of its mascot, Duo.

Running from 1 to 30 June, the campaign allows eligible users who previously maintained a streak of at least 30 days to restore their longest streak by completing three lessons in a single sitting.

According to Duolingo, recovering lost streaks has been one of the most common requests from users. Over the past year, tens of thousands of learners across more than 80 countries have reportedly asked for their streaks to be reinstated through social media channels.

The company said the initiative aims to remove a key barrier preventing lapsed learners from returning to the platform. Duolingo added that losing a streak is frequently cited as a reason users disengage from language learning, despite the streak feature serving as a strong motivator for maintaining daily learning habits.

Alongside the streak recovery event, Duolingo is highlighting a series of product updates introduced since many users last engaged with the app.'

These include expanded advanced language content across its nine most popular language courses, as well as a range of new free learning tools such as 'Speaking adventures', 'Flashcards', 'Explain my answer' and 'Practice hub'.

The platform has also introduced a Duolingo score system designed to help learners track progress against curriculum standards.

Beyond languages, Duolingo said its Chess course has become the fastest-growing subject on the platform, reaching seven million daily learners in under a year. The company has also expanded its Math course offering, which covers concepts ranging from elementary to high school levels.

Eligible learners will see the streak recovery option appear within the app during the campaign period.

"For years, learners have asked us for a way to recover lost streaks, and Duo’s birthday felt like the right moment to do it,” said Cem Kansu, chief product officer at Duolingo. “We’re excited for learners to come back and discover an even better learning experience, with more ways to practice and even more to learn than when they left.”

In tandem, Bozena Pajak, head of learning science at Duolingo said, "Streaks represent hard work, time, and energy spent learning, so they mean a lot to our learners. 'Streak revival' gives people a chance to pick learning back up without feeling like they’ve lost all the progress and momentum they built before.”

The streak recovery initiative comes as Duolingo continues to expand its engagement efforts beyond learning features.

Last year, the company launched Duolingo Ads, a mobile-first advertising platform designed to help brands connect with Gen Z audiences through character-led campaigns. The offering leverages the app's cast of personalities and blends branded storytelling with Duolingo's signature humour and playful tone.
