I’ve maintained a language streak for over a year, but have stubbornly checked the app daily, even when the engineered prompts from Duolingo’s owl felt more like guilt-tripping than encouragement. That ends now. And the app’s new energy system doesn’t simply adjust the experience for free players — it fundamentally alters how and how much you can learn in one go. It’s over after testing it out in multiple sittings.
What the new energy system changes for free learners
For years, free users operated on a hearts model: you had five hearts, and you lost only one when you made a mistake. If you were accurate, you could study for a long time. With energy, you start the day with a “battery” that drains with every exercise — even if you’re perfect. You can inch it back up by getting some right answers in a row, but the meter counts down just for playing.

Refills are now a menu of sources of friction: spend in-app currency, watch ads where one can, grind through practice material for tiny top-ups, or subscribe to bypass the system altogether. The daily “recharge,” in my experience, was not always a return to full battery. The upshot is that there’s a timer for free study sessions now, built right in.
Why the energy system undermines meaningful learning
The issue is not merely annoyance — it’s pedagogy. Successful language learning uses spaced repetition and retrieval practice, not a time limit. The research summarized by the American Psychological Association and popularized by cognitive scientists in Make It Stick suggests that depth of practice is more important than streaks or speed. With each screen that needs to be fed energy, you’re nudged toward shorter, easier tasks to preserve battery life rather than efforts at more challenging learning where retrieval is hardest and learning sticks.
That trade-off made itself apparent again in my Mandarin practice. Character drills are easy and relatively risk-free, so they hardly make a dent in the battery. Full lessons that blend listening, reading, and recall can really bite off and consume a lot of time, not to mention a couple of errant mistakes will cull it for the day. I always hit a wall of energy after the third lesson, even on clean runs, so it is hard to really get momentum or do daily missions more focused on new content over review.
Course updates compound the friction introduced by energy
Of course, refreshes are always a double-edged sword — it’s good to get something new through content, but updates often rely on presumed knowledge and spread the introduction of vocabulary thin. It’s not easy when you are halfway through a path to figure out where new phrases were introduced. Before, I would be able to bulldoze my way through learning for longer periods. Without energy, that coping mechanism disappears. The system itself punishes the exact persistence required in order to clean things up post-refresh.
A monetization pivot, driven by game mechanics
Energy meters are a staple of free-to-play games because they create predictable breaking points that guide users toward advertisements or upgrades. Industry analyses of the mobile industry, by companies such as data.ai and Sensor Tower, have covered how limiting progression can increase conversion. Not surprisingly, a language app has now taken the same playbook. The company’s shareholder updates have emphasized rapid growth in both paid subscribers and revenue, and an energy model focused on shuffling free users up the price ladder.
The tension is that learning a language is not akin to a casual game of laser tag. ACTFL focuses on long-term, meaningful practice in the four communication skills. A meter that empties no matter where it stands is an anti-incentive to the sort of extended immersion on which you must rely to reach anything beyond recognition and even into recall/production level territory for languages with different writing systems (like Mandarin).
Community backlash and trust concerns around energy
Community forums and the r/duolingo subreddit are filled with posts from users claiming the change punishes competency and stifles progress. Some regions have ads that players can watch to restore energy; others do not. Partial day refills are reported by a few users. That inconsistency erodes trust. When core mechanics turn murky, learners no longer act as lesson planners, but become meter gamers.
Consumer groups in Europe and the US have sounded a general alarm about “dark patterns” that transmute friction into revenue. And while this change isn’t skirting any legal boundaries at face value, it skates uncomfortably around a design principle that favors monetization over learning — particularly in the case of a tool marketed as an educational sidekick.
Where I’m going instead for longer, unrestricted study
I’m trying out alternatives that let me study until I feel like stopping. SuperChinese, on the other hand, provides structured Mandarin lessons and longer blocks of practice. I’m also keeping an eye on Google’s new practice features and “Little Language Lessons” for bite-sized reinforcement, and I’ll add graded readers and spaced-repetition flashcards to take control of the session length and review pace.
Free plans will always come with compromises. But the good ones make their restrictions feel fair and pedagogically valid. A meter that depletes regardless of whether you are right or wrong signals the opposite. After hundreds of days of showing up, I’m opting for tools that reward diligence instead of rationing it.
If the app rethinks energy — reviving mistake-based caps, providing full daily refills, or aligning missions with review science — that would make me reconsider. Until it’s figured out, this is where my streak ends and my learning goes elsewhere.
