We tracked down 18 of the best apps for learning Danish, including 1 you can use for free. Our top picks right now are DanishClass101, Babbel and Busuu. Every entry below is hand-checked, and the ones that teach you come first — with free options ahead of paid ones wherever they are as good.
Hundreds of short dialogue-plus-explanation lessons with transcripts, line-by-line breakdowns, word lists and a spaced-repetition trainer, arranged into level pathways. For a language as underserved as Danish, this is the largest structured audio course you can buy, and the free feed alone gives you a lot. The usual caveats apply: constant upsell emails, some very old lessons, and the top tiers are poor value unless you use the tutoring.
Subscription-only after a handful of free intro lessons, with the monthly price falling steeply on longer plans. Lessons are short, dialogue-first and explain grammar properly, which makes it a much more serious beginner course than Duolingo. It covers only 14 languages and effectively stops around B1, so it is a stepping stone rather than a destination.
Covers 14 languages along an explicit CEFR path, and its best feature is the community exchange: you submit short writing or speaking exercises and real native speakers correct them, free of charge, in exchange for you correcting theirs. The free tier is limited to core lessons; Premium unlocks grammar, offline and the full path. A solid Babbel alternative if you specifically want writing practice with human feedback.
Thirty-minute audio lessons force you to produce sentences out loud before you see anything written, which builds unusually good accent and recall. Subscriptions run about $15–21/month (all-access covers 50+ languages), and older courses are often available through public libraries. It is slow and vocabulary-light by design, so pair it with reading — but for commute or walking time it is the best use of otherwise dead hours.
Lessons build outward from real conversations with colour-coded literal translations and cultural notes, and the catalogue includes endangered and indigenous languages nobody else covers. Retail pricing starts around $10/month, but a very large number of public libraries and universities give patrons free access — check yours before paying. Content depth per language is modest, so it suits travellers and early learners more than people pushing toward B2.
You listen to and repeat thousands of native-recorded sentences on a spaced schedule, which builds fluent output patterns without explicit grammar study. It covers 60+ languages and keeps nine minority languages (Catalan, Welsh, Taiwanese, Kurdish and others) permanently free as a preservation effort. It is expensive at roughly $20–40/month, and the repetition is monotonous — most reviewers call it effective but overpriced, so try the 7-day trial first.
A reading app built around finishing complete books: you pick a story at your level, tap a word or reveal a sentence's English translation when you get stuck, and it saves the words you looked up. There is one complete free book in every language and you can read a free chapter on the website without installing anything; the rest of the 1,100-book library is paid. The library is uneven: Ukrainian, Indonesian and French have dozens of stories, while Icelandic, Estonian and several Balkan languages have one or two. It is not the same as Storyglot's European Portuguese readers (storyglot.com), which are a separate project with the same name.
Free on desktop, Android and web; the iOS app is a one-off paid purchase that funds the project. The interface is dated and the options are overwhelming at first, but nothing beats it for retaining vocabulary over years. Most effective when you stop grinding premade decks and start mining sentences from things you actually read or watch.
The free tier is genuinely usable (ads plus a limited 'hearts' system); Super removes both for about $96/yr. Its real value is streak-driven consistency for absolute beginners, and the smaller courses are thin machine-assisted content rather than the polished Spanish or French trees. Treat it as a warm-up habit, not a curriculum — nobody reaches conversational fluency on Duolingo alone.
The 'learn with locals' video clips are the distinguishing feature — you hear real people at real speed rather than TTS. Be aware that Memrise moved user-created community courses off the main app in 2024 onto a separate site, which gutted what many long-time users valued most, and the app has leaned hard into AI chat features since. Fine as a phrase-and-vocabulary app for major languages; if you came for the community decks, use Anki instead.
Built-in correction tools let partners fix your messages inline, and the social 'moments' feed gets you corrections from strangers without arranging a call. Free for the core exchange; VIP adds more translations and simultaneous target languages. The persistent caveat is that a fair share of users treat it as a dating app, and exchange partners are unreliable — it works best once you already have some output to correct.
Import podcasts, articles or ebooks, tap unknown words for definitions, and LingQ tracks your known-word count over time. The free tier caps how many saved words you can keep, so serious use means paying (~$13/month or less annually). The interface is clunky and the built-in SRS is weaker than Anki, but the reading-plus-audio workflow with 50+ languages is hard to replicate elsewhere.
Built on Tatoeba sentences, it drills words in context by frequency band across 50+ languages and 170+ language pairings, with a genuinely generous free tier. It explicitly starts where beginner apps end, so it is the natural 'what now?' answer for someone who finished a Duolingo tree. Sentences are crowd-sourced and occasionally awkward or oddly specific, and it teaches nothing about grammar explicitly.
Same idea as HelloTalk but with vetted profiles and one-to-one partner matching rather than a social feed, which makes it noticeably less spammy in practice. Texting partners is free; calling them in the app is part of the paid Pro tier, and the app also sells paid tutors. Both apps live or die on finding one or two committed partners, so expect to message a lot of people before anything sticks.
Unlike most apps it is built around producing speech: you repeat, roleplay and converse with an AI tutor that gives pronunciation and phrasing feedback in real time. Covers Spanish, French, Korean, Japanese, Italian and Chinese for English speakers, with a 7-day trial then a subscription (roughly $20/month or $99/yr). Good for overcoming the fear of speaking before your first human lesson, but an AI will not push back or drift off-script the way a real conversation partner does.
A 501(c)(3) nonprofit: you shadow native audio, record your own version, and a real human coach returns feedback — 10 free submissions a month, unlimited for about $20/month, with full scholarships for anyone who needs one. Covers French, Spanish, Chinese, Japanese, Korean, German, Italian, Portuguese, Russian and English. It only fixes pronunciation and delivery, so it complements rather than replaces conversation practice.
The heavyweight immersion toolkit: one-click sentence mining with audio, screenshot and definitions, plus its own SRS and known-word tracking, for 11 languages including Japanese, Korean, Mandarin and the major European ones. A 10-day free trial then a subscription (roughly $10/month). Overkill unless you are committed to a sentence-mining routine — if that describes you it saves hours a week, otherwise Language Reactor's free tier is enough.
A streaming service where every show has clickable dual subtitles and saved words become flashcards, covering 15 languages with apps on phone, Roku and TV. It solves the 'what do I watch' problem for languages where Netflix's catalogue is thin. The library is much smaller than a mainstream streamer and it is subscription-only — if you already pay for Netflix, Language Reactor's free tier does most of the same job.
