You reached B2 in French, and then progress stalled. The beginner apps that carried you here now feel too easy. Yet you still make small errors that a native never would, and formal writing still trips you up. That gap between “I get by” and “I sound native” is where most learners quit.
The fix is to stop using apps built for foreigners. Instead, train like a native: use the apps French native speakers use themselves to perfect their spelling, grammar, and vocabulary. In this guide, I will showcase 5 native French apps, a comparison table, July 2026 pricing, and a routine to combine them. Bonne lecture !
Quick comparison: 5 native French apps for advanced learners

| Projet Voltaire | Spelling and expression, with a certificate | Free trial levels | Module €39.60/yr; Certificat Voltaire €59.90-69.90 extra |

Why native French apps beat learner apps at B2 and above
The apps on most French lists teach you to order a coffee. That job is done by B2. What still separates you from a native is the written code. That means accents, accord, verb endings, register, and the precise word over the near-synonym. Beginner apps barely touch this. Native apps, however, train nothing else.
So every pick below is a tool that French speakers use on their own language. French students, professionals, and writers reach for these to polish their spelling and style, and not forget the tricky grammar rules! That is exactly the work a B2 learner needs to reach C2.
Master spelling and grammar
At C1 and C2, small mistakes give you away: a missed accord, a wrong accent, a verb ending a native nails. These three apps target that precision directly, and each trains you rather than merely correcting you.
Français Avec Marcel: best all-round for advanced spelling and grammar
Français Avec Marcel is the app French natives use to fix their own spelling. That makes it a strong B2-to-C2 tool for advanced learners too. Marcel, a virtual mentor inspired by Proust, explains the rules behind the most common mistakes. He then drills them with quizzes and graded dictations.
What sets it apart: themed lesson cards on tricky rules, dictations at several levels, and a chat that answers any grammar question. The dictation feature in particular forces the exact spelling and accord skills that separate B2 from C2.
What could be better: the interface is entirely in French, which suits advanced learners but blocks beginners. The focus is written accuracy, so pair it with real conversation for speaking.
Pricing (July 2026): free to download; Premium from €9.99/month or €49.99/year, with a €124.99 lifetime option.
Best for: B2 and above learners who want to write French that reads as native.
Projet Voltaire: best for structured training and a recognized certificate
Projet Voltaire is the reference for spelling training in France. Schools and companies use it, and its adaptive engine builds a path around your weak points. Crucially, it also prepares you for the Certificat Voltaire, an exam that French employers actually recognize.
What sets it apart: an AI-driven path that revisits your errors, broad coverage of expression and style, and a CV-ready certificate. Furthermore, the content is written by a committee of French language experts.
What could be better: the interface feels institutional rather than playful. In addition, the exam is a separate cost, and the full professional programs are pricey.
Pricing (July 2026): free trial of the first levels. An individual module costs €39.60 for 12 months. The Certificat Voltaire exam is extra: €59.90 for orthographe, €69.90 for expression.
Best for: methodical learners who want proof of their level, not just practice.
Orthodidacte: best alternative with the Certificat Le Robert
Orthodidacte is Projet Voltaire’s main rival, and it earns the comparison. The platform trains spelling, grammar, conjugation, and vocabulary through short adaptive exercises. Moreover, it delivers the Certificat Le Robert, a second recognized French certification.
What sets it apart: broad coverage that reaches beyond spelling into vocabulary and style, clear video explanations, and a personalized path. As a result, it suits learners who want variety rather than pure drills.
What could be better: it is less famous abroad than Projet Voltaire, so name recognition is lower. The interface is French only.
Pricing (July 2026): free trial. A subscription costs about €105 a year (€8.75/month). The certifying path runs about €210 a year (€17.50/month), and the Certificat Le Robert exam is sold separately.
Best for: learners who want wider coverage and a Le Robert certificate.
Nail conjugation and vocabulary
Fluency also lives in the details you look up: an irregular subjunctive, the exact shade of a synonym, a register you half-remember. Two native references settle these questions and teach you as you go.
Bescherelle: best for conjugation and dictées
Bescherelle is the conjugation authority every French pupil grows up with. Its apps let you check any verb in any tense, then test yourself with quizzes and dictées. Because conjugation errors are a classic advanced-learner tell, this is targeted practice.
What sets it apart: complete verb tables, graded dictées, and the free Défi Bescherelle game that drills rules through play. In addition, the brand carries genuine authority in French classrooms.
What could be better: the apps are more reference and quiz than a full course. Meanwhile, design varies across the different Bescherelle titles.
Pricing (July 2026): the conjugation app and the Défi Bescherelle game are free. Some other titles, such as older dictée apps, cost a few euros.
Best for: learners who want to lock down conjugation and test it with dictées.
Le Robert: best native dictionary for nuance and synonyms
Le Robert is one of the two great French dictionaries, alongside Larousse. At an advanced level, a monolingual French dictionary is a learning tool, not just a lookup. You read definitions in French, compare synonyms, and absorb register and usage.
What sets it apart: precise definitions, rich synonym lists, usage notes, and etymology. Consequently, it builds the nuanced vocabulary that C1 and C2 demand.
What could be better: it is a reference, so you supply the discipline to study, not just search. However, the mobile app pushes some features behind a paid tier.
Pricing (July 2026): the online dictionary is free. The mobile app is freemium, with a premium subscription you can try for €1 the first month.
Best for: learners building a native-level vocabulary and an ear for register.
Final recommendation
Reaching C2 is not about one perfect app. It is about training the written code the way a native does, then backing it with real conversation. For most advanced learners, that means a daily precision tool, a certificate-backed program, and a strong dictionary.
If you want a place to start, begin with Français Avec Marcel for daily spelling and grammar. Then add Projet Voltaire or Orthodidacte to work toward a recognized certificate, and keep Le Robert open as you read. That combination trains the exact skills that turn a solid B2 into a convincing C2.
You do not need to spend to practice every day, either. lalanguefrancaise.com, from the same team behind Marcel, publishes free spelling articles, quizzes, and dictations. Each one breaks down a common trap, such as a confusing pair of homophones, in plain terms. So use it to fill the gaps between paid sessions and keep your written French sharp. Bonne chance !
