Forty-one languages live inside Mondly's course catalog, and exactly one of them has held my attention long enough to matter: Italian, the language my grandmother never got around to teaching me. Seven years of picking up and setting down language learning apps has taught me that the real filter for an adult beginner isn't which app has the prettiest streak flame or the slickest onboarding video. It's whether the tool matches how you actually intend to use the language once the free trial ends. This is the app comparison I keep coming back to when a reader asks which one is worth keeping in 2026, after testing enough of them to know exactly which subscriptions I regret.
Quick disclosure before the breakdown: several of the links below are affiliate links, and if you click through and end up paying for one of these apps, I earn a commission at no extra cost to you. I only write about apps I've actually paid for and used long enough to have a real opinion, including the ones I eventually cancelled because the UI made me want to throw my phone across the room. More detail lives on the editorial policy page.
Why a Streak Isn't the Same as a Skill
A streak counter and an actual habit are not the same thing, no matter how many apps want you to believe otherwise. Most beginner apps lean on a Spaced Repetition System to keep vocabulary sticky, which works well enough for matching a word to a picture (eating my vegetables, basically), but recalling a flashcard is a different skill from generating your own sentence on the fly (I still mix up per and da more often than I'd like to admit), and that gap is where most subscriptions quietly stop delivering. Gamified drills are excellent at getting you to open the app every morning; they're much worse at getting you to build anything you didn't already see on the screen.
I once set a hard streak goal on Duolingo, built it up past the forty-seven day mark, then lost the whole thing to a missed midnight cutoff during a stretch of deadline work, and rage-quit the app rather than start over. The streak wasn't teaching me Italian at that point — it was just a number I resented losing. That's worth naming before comparing any of the apps below: the one that keeps you logging in daily isn't automatically the one building a skill you can actually use in a real conversation.
Mondly: Built for Habit-Building, Not Deep Grammar
Mondly by Pearson is the one I keep paying for despite everything else on this list, mostly because it's the easiest app to actually open. The catalog covers forty-one languages, including several nobody else bothers with (Hebrew, Tagalog, Norwegian, Catalan, Latin), which matters if you're the type who still daydreams about Japanese while supposedly focused on Italian. The Daily Lesson is built around a streak counter, tuned for the kind of habit-stacking that gets a lesson finished over eggs at Short Stack Eatery on East Johnson Street some mornings before the day gets away from me. My thumbs go warm after a long enough stretch of vocabulary swipes, the same warmth a phone screen gets after too many minutes of scrolling, and that's usually my cue to close the app and call it done.
For anyone reconnecting with a language a parent or grandparent once spoke at home, the calculus shifts — a heritage learner already carries half-remembered vocabulary and pronunciation instincts an app like this can build on differently than it would for a total beginner, though that's its own separate conversation. Mondly's translation-heavy exercises feel mechanical next to something audio-based, and the voice recognition can get stuck on a single word for no obvious reason, which is its own flavor of frustrating when you're fairly sure you said it correctly. I tried the VR mode on a Meta Quest too, which is particularly useful for a beginner learning more than one language at once, standing in a virtual restaurant ordering a drink that felt less mortifying than doing it in person, though the headset's voice recognition was just as stubborn.
Choosing Rocket Languages When You're Done With Subscriptions
Rocket Languages solves a different problem: it's a one-time purchase with lifetime access, which is the whole appeal if you're tired of subscriptions you're too lazy to cancel. Whether that one-time cost is actually worth it comes down to whether you'll use the material long enough to make the math work in your favor, which is a calculation worth doing before you buy rather than after. The lessons are audio-first, built for commutes, dishes, or a treadmill, and the narrator has been in my ears long enough that I've started treating him like a houseguest who's overstayed his welcome — I have opinions about his pacing, but he knows the material. There's a voice-recording feature that plays your attempt back against a native speaker's, and a sixty-day money-back guarantee that's more generous than most of what's on this list.
Non-Roman scripts get their own toolset inside Rocket too, which is the part that makes me think seriously about finally starting Japanese one of these years — script acquisition is a different mountain from the speaking drills entirely, and not one this piece is trying to climb. The catalog tops out at twelve languages — Spanish, French, Italian, German, and Japanese among them, plus a handful of others including Mandarin, Korean, Russian, and Arabic — so if you're chasing something further off the beaten path, look elsewhere. The desktop interface looks like it hasn't been touched since 2018, which is a fair complaint, but the course structure underneath is closer to a textbook than a game, and that structure is what actually moved my Italian forward. I wrote more about trading a daily streak for a lifetime seat if you want the longer version of swapping app gamification for an audio course.
Is EF English Live Worth It If You Only Need One Language?
EF English Live only makes sense for one specific case: you specifically need English, not Italian or Spanish or anything else on this list. Once that's true, it stops being a language app and starts being closer to a full digital school. Live group classes run every 30 minutes, around the clock, plus 1-on-1 private lessons you can book on demand, and completed courses map to CEFR levels across sixteen tiers of instruction, with a Pearson-recognized certificate at the end. None of that matters if your actual goal is ordering dinner in Rome.
Conversation-readiness looks different from a passed quiz, and live classes are the fastest way I've found to test it — there's no interface to hide behind once a certified teacher is waiting for you to actually talk. That's also the fastest route past the anxiety that keeps a lot of adult beginners quiet in their first real conversations, since you either speak or the silence gets awkward fast. The clearest proof I'd actually retained anything wasn't a lesson score. It was texting my friend Piotr an Italian joke, half expecting a laughing-face emoji back, and instead getting three lines of correction in Italian, because if there's one thing quietly competitive Piotr can never resist, it's a chance to one-up somebody else's language flex.
EF isn't cheap next to a self-study subscription, and the commitment is real: most plans lock you into six or twelve months, with a refund process that has a rough reputation, so it's worth being certain English specifically is the goal before signing anything.
Which App Should You Actually Keep?
The honest answer depends on what you're actually optimizing for, not which app has the best reviews this year. If the goal is professional-level English with real speaking practice, EF English Live is worth the higher cost and the commitment, because nothing else on this list puts a live teacher in front of you on a schedule. If you're done paying monthly for something you keep forgetting to open, Rocket Languages is the better fit — pay once, get a structured course, and use it on your own schedule with no countdown clock. Mondly earns its keep as the low-stakes habit tool: quick vocabulary hits between meetings, useful for keeping several languages warm at once, but not the thing that's going to carry an actual conversation on its own.
A reader named Anneliese Torrington emailed after leaving a comment on an earlier post, mostly wanting to know which of these actually work well with a screen reader or let her bump up the text size before she commits to a subscription — a fair question none of these marketing pages answer clearly, and one worth checking yourself before you pay for anything. Test the free trial with whatever accessibility settings you actually need, not the default demo the app ships with.
If you only take one thing from this: stop paying for the app you've stopped opening, and pick the one that matches what you're actually trying to do with the language, not the one with the longest streak flame. For me that's meant keeping EF English Live in rotation for high-intensity speaking practice and Rocket Languages for the structured foundation, while Mondly stays around for the mornings when a quick vocabulary hit is all I've got time for.
