Best Language Learning Apps and Classes, Compared Honestly
Nothing on this page will make you fluent by itself, and the products that pretend otherwise are the ones to distrust. Apps build vocabulary, grammar patterns and daily habit. People build speech. So the useful question is not which app is best, it is which job you are buying and when to move to the next one.
The short answer: start free with Duolingo, which states that every course is free; add a human as soon as you can form sentences, either on demand through italki (published bands of 5 to 120 dollars per lesson) or on a schedule with Lingoda (60-minute live classes, certificate per CEFR level); and if English is not your first language, Mondly teaches from your own language instead. Everything below is quoted from company documentation and verified July 23, 2026.
The comparison nobody publishes: how each one bills you
Feature lists in this category are interchangeable. What actually separates these products, and what decides whether you lose money, is the billing mechanic buried in each set of terms. Here they are side by side, each quoted from the company's own documentation on July 23, 2026.
| Product | What you buy | How it renews | What expires, and when | Refund position |
|---|---|---|---|---|
| Duolingo | Nothing, unless you want ad-free or AI features | Paid tiers are subscriptions | Nothing; free courses stay free | Not applicable to the free tier |
| italki | Credits, then lessons priced by each teacher | No subscription at all | Credits after 12 months of account inactivity; packages 6 months after purchase | "No refunds will be given for italki Credits purchased"; trial guarantee twice, within 48 hours |
| Lingoda | A bundle of 60-minute classes | Every four weeks until cancelled | Credits roll over while subscribed, then cannot be accessed after the last payment cycle ends | 14 days from subscribing, minus classes taken |
| Mondly | App access, or a lifetime membership | Monthly or yearly until auto-renew is off | Nothing expires; access ends when you stop paying | "All amounts are non-refundable unless otherwise stated"; 14-day cooling-off only in the UK and EU |
| Preply | A subscription with one chosen tutor | Every 28 days, for a fixed number of lessons | Unbooked lessons expire at renewal; booked lessons are protected | Up to 2 free trial replacements per account, returned to your balance rather than as cash |
| Babbel | Access to self-study courses | Automatically, unless cancelled; paid in advance for each period | Access ends with the subscription | Company states price and terms vary by location and purchase channel |
Read that table before you read any feature list. Three of these six take your money in a form you cannot get back: platform credit that expires, class credits that die with the subscription, and subscriptions that are non-refundable by default outside Europe. None of it is hidden, and all of it is in the terms rather than on the buy button.
Three shapes, and the one question that picks yours
Ask yourself one thing: do you need somebody to hear you speak?
Duolingo, best free starting point
Duolingo states plainly that everyone can access its courses without spending anything, whether you enrol in one course or forty, that free learners see advertising, and that paid subscribers get an ad-free experience and extra features. Its tiers are Super, described as ad-free with gamification perks, and Max, adding AI features including roleplay and grammar explanations tailored to your mistakes.
Use it for: the first few hundred words, the alphabet or writing system, and the habit of showing up daily. Do not expect: conversation, pronunciation correction, or a plan for what to do once the tree is finished. We publish no price for Super or Max because the pricing page returned no readable figure when we checked on July 23, 2026. No commercial relationship, no link.
italki, best for one-to-one speaking
A marketplace where you book individual lessons with teachers who set their own prices, with no subscription. Professional teachers must upload documents showing training and teaching experience; community tutors provide conversation practice and need no teaching documents. Published bands are 10 to 120 dollars per lesson for professional teachers and 5 to 120 dollars for community tutors, and italki's own pages put typical tutors at 4 to 60 dollars an hour with professionals commonly 18 to 32.
The mechanic to respect: you buy credits rather than lessons, no refunds are given for credits purchased, credits expire after twelve months of account inactivity, and packages expire six months after purchase. There is a genuine protection: the satisfaction guarantee covers trial lessons, twice, claimed within 48 hours of the lesson time. Detail in our italki review and cost breakdown.

Lingoda, best for structure and a certificate
An online school rather than a marketplace: 60-minute live classes available 24 hours a day, taught to small groups the company describes as three to five students, following a CEFR-aligned curriculum, with free downloadable materials and a certificate for each level completed. Languages are German, English, Business English, French, Spanish and Italian, and the ceilings differ: A1 to C1 for English and German, A1 to B2 for French, Spanish and Business English, A1 to A2 for Italian.
Published plan totals ran €44.99 to €290.99 depending on bundle size and class type. Two dates to diary: the seven-day trial starts at account creation and converts to a payment automatically, and unused credits stop being usable once your last payment cycle ends. Detail in our Lingoda review.

Mondly, best for learning from your own language
A self-study app covering 41 languages that teaches from your native language rather than routing every course through English, which the company describes as more than a thousand language combinations. The free tier is real; Premium adds conversation practice, pronunciation lessons, grammar guides, conjugation tables, kids content and augmented-reality lessons.
Set expectations correctly: the conversation feature is scripted practice, not an open-ended tutor, and no app of this kind produces fluency. The refund position is regional, with a 14-day cooling-off right only for UK and EU subscribers. Its ratings split sharply, 4.7 out of 5 from 33,000 US App Store ratings against 2.6 out of 5 from 779 Trustpilot reviews, both checked July 23, 2026, with billing rather than teaching driving the low scores. Detail in our Mondly review.

Preply, the marketplace that bills like a subscription
Preply is the obvious alternative to italki and it is structurally different in a way that matters more than any feature. A Preply subscription is between you and one tutor, and every 28 days you are automatically charged for a fixed number of lessons with that person. Lessons you have already booked are protected; unbooked lessons expire at renewal. You can pause once per cycle for up to 20 days if you apply before the billing date, and cancelling must be done at least a day before the next billing date.
On trials, Preply allows up to two free trial replacements per account if a tutor did not attend or the lesson did not meet expectations, and it is explicit that a replacement moves your trial back to your balance rather than granting an extra free lesson.
How to choose between them: if you want to commit to one tutor and let a recurring charge enforce the habit, Preply's model is designed for that. If your weeks are unpredictable and you would rather pay per lesson and switch teachers freely, italki's model fits better, at the cost of credits that expire if you go quiet. Our full italki vs Preply comparison takes this apart line by line, including the refund route Preply publishes and italki does not. We have no commercial relationship with Preply and do not link to it.
Babbel, structured self-study
A well-regarded structured course for solo study. On price, its help centre states the cost "can vary depending on several factors, including your location, the duration and type of your subscription, and whether you purchase directly through Babbel, partner websites, Google, or Apple", that you pay the full amount for each renewal period in advance, that subscriptions renew automatically unless cancelled, and that only the Lifetime subscription and the gift option are one-time payments.
We publish no Babbel figure, for the reason the company itself gives: there is no single price. Treat any article that quotes you one as out of date or region-specific. No commercial relationship, no link.
Which one, for whom
| If this is you | Start here | Because |
|---|---|---|
| Absolute beginner, unsure you will stick with it | Duolingo | Every course is free, so the only thing you risk is time |
| Can form sentences, want to speak | italki | One-to-one practice from a 5 dollar floor, no subscription |
| Quit before because you never booked | Lingoda | Fixed classes and a curriculum do the discipline for you |
| Want one tutor and a routine you cannot skip | Preply | A 28-day subscription with a single tutor enforces the rhythm |
| First language is not English | Mondly | Courses taught from your own language, not through English |
| Want a structured solo course and no scheduling | Babbel | Self-study curriculum, though the price depends where you buy |
| Learning Spanish specifically | See our Spanish guide | Same sequence, applied to the most crowded market |
Four rules that save more money than any discount
- Do not pay for the vocabulary stage. Two products here have genuine free tiers and both cover it.
- Buy the human earlier than feels comfortable. One paid trial lesson tells you more about your level than a month of streaks.
- Match the billing to your calendar, not your ambition. Subscriptions punish quiet months; pay-per-lesson punishes indecision.
- Read the expiry rule before the feature list. Credits that vanish are the most common way people lose money in this category, and every rule in the table above is public.

Frequently asked questions
What is the best language learning app in 2026?
There is no single best app, because the products do different jobs. For a free daily habit and your first few hundred words, Duolingo covers it because every course is free. For actually speaking, a live teacher is the only thing that works, and italki is the cheapest reliable route with published bands of 5 to 120 dollars per lesson. For a fixed schedule and a certificate, Lingoda runs 60-minute live classes. For self-study in a native language other than English, Mondly. Verified July 23, 2026.
Can any app make you fluent?
No app can. Every self-study app in this comparison builds vocabulary, grammar patterns and daily habit, and none of them can hold an unscripted conversation or correct your pronunciation the way a person does. The apps that admit this are the honest ones. Treat an app as the layer that gets you ready to speak, and budget for a human once you can form sentences.
What is the difference between italki and Preply?
Both are marketplaces of individual tutors, but they bill differently, and that is the deciding factor. italki has no subscription: you buy credits and book lessons one at a time, with credits expiring after twelve months of account inactivity and packages after six months. Preply is a subscription with one tutor, charged every 28 days for a fixed number of lessons, where unbooked lessons expire at renewal and a plan can be paused once per cycle for up to 20 days.
Which language app is genuinely free?
Duolingo is, in the strong sense: the company states you never have to pay to use it, whether you enrol in one course or forty, with advertising shown to free users and paid tiers adding an ad-free experience and AI features. Mondly also has a real free tier covering daily lessons, challenges and vocabulary review. Free trials elsewhere are a different thing: Lingoda's seven-day trial converts to a payment automatically unless cancelled.
How much should I expect to spend?
Nothing at all for the vocabulary stage, since two of these products have genuine free tiers. Speaking is where money starts. Using italki's published ranges, a weekly hour with a community tutor is roughly 20 to 60 dollars a month and with a professional teacher roughly 72 to 128 dollars, which is our arithmetic rather than a quote. Lingoda publishes plan totals from 44.99 to 290.99 euros depending on bundle size and class type.
