User Reviews

Users find the app effective and well designed for learning French, especially for basics and classroom use. Recurrent negatives are technical instability (crashes/auth errors), a strong paywall, and poor access to lesson review or exercise retakes; some modules (vocabulary/adaptive system) are also criticized. Many users prefer the website version for reliability.

Pros

Effective for learning French orthography and grammar (helps progress/master basics).
Well‑designed concept and exercises that support practice and classroom use.
Useful for tracking progress and preparing tests.
Website/version on the web is praised and seen as a strong complement to the app.

Cons

Stability and bugs: crashes, incorrect marking of answers, authentication and in‑app purchase errors causing lost progress.
Most content locked behind a paywall; only first levels are free and many users find it expensive.
Limited access to lessons and reviews: users cannot easily reread rules or redo exercises without losing progress or waiting.
Adaptive system and some modules (notably vocabulary) have flaws: inability to disable adaptivity, missing final evaluations, and inaccurate synonym pairs.

Ce serait mieux si les messages "Aucun cours associé, Cette règle ne possède pas encore de cours" était remplacé par les cours qui, de fait, existent (les explications sont en effet dispo à chaque exo mais au delà des premiers modules on ne peut donc plus y accéder directement, sans refaire les exercices donc en réinitialisant une partie des progrès. :/ Aussi, il serait appréciable après avoir fait les évaluations finales de pouvoir revoir les détails, ie cours assimilés ou non assimilés.
