Busuu's standout feature is having real native speakers correct your writing. That's genuinely useful for an adult learner — but it means your kid's exercises are seen and responded to by strangers. Here's what that means in practice.
💡 Busuu is a well-built app, but it was designed for adults, with a community-correction feature that puts a kid's work in front of other users. Lumi Lingo is closed by design — no community, no stranger contact — and built kid-first from age 4 up.
What Busuu Actually Is
Busuu is a well-regarded language app, and it earned that reputation honestly: structured courses across a dozen-plus languages, tiered pricing from free to a premium "Busuu Plus" tier with tutoring add-ons, and a genuinely clever feature where real native speakers review and correct your written exercises. For an adult trying to sound less like a textbook, that human feedback loop is one of the more useful things a language app can offer.
The catch, for a parent specifically evaluating this for a child: that community-correction feature means your kid's written answers get posted where other Busuu users — adults you've never met — can read them and reply. Busuu does moderate its community and most interactions are almost certainly benign, but "almost certainly fine" is a different bar than "built not to have the interaction happen at all." Busuu's own account terms generally set a minimum age, which reflects that the product wasn't designed around young children in the first place.

Worth Knowing Before You Choose
Busuu's moderation likely catches most bad actors, but "likely" isn't the same as a closed system with zero stranger contact
If your kid is a teen with strong self-direction, Busuu's structure may still work well — this is really a judgment call about your specific child
For a younger kid, or one you'd rather not have interacting with strangers online at all, a kid-first app like Lumi Lingo removes the question entirely
Frequently Asked Questions
Does Busuu let strangers interact with my child?
Busuu's core feature is community correction: you write a short exercise in the language you're learning, and native speakers in Busuu's global community review and correct it, then you can reply to say thanks. That means a child's writing and a reply thread can be seen and responded to by adult strangers on the platform. Busuu does have some content moderation, but it wasn't designed as a closed, kid-only environment. Lumi Lingo has no community, chat, or stranger-interaction feature of any kind — every lesson is self-contained between the kid and the app.
What age is Busuu designed for?
Busuu markets itself to adult and teen learners preparing for travel, work, or exams, and its account terms generally require users to be at least 13 (16 in some regions) partly because of the community features. It isn't built for young children. Lumi Lingo is built kid-first from age 4 up, with no age-gated community component to work around.
Is Busuu's free version enough for a kid to learn a language?
Busuu's free tier is quite limited — most of the structured course, the community correction feature, and offline access sit behind a paid plan. A parent evaluating it for a child would likely need the paid tier to get meaningful content, at which point it's worth comparing directly against a kids-first option like Lumi Lingo's $3.99/month plan, which covers up to 8 kids on one account.
Does Busuu require speaking into a microphone?
Busuu includes speaking exercises and pronunciation practice as part of its course, which for some kids is a valuable skill-builder but for a shy or self-conscious child can be a source of anxiety, especially if reviewed by other community members. Lumi Lingo never requires a kid to speak into the device — every question is answered by tapping or typing.
