### 1/5 — Audio problems

*2026-05-27*

It disconnects my airpods when using mic.

### 1/5 — Money grab.

*2026-05-13, version 3.23.2*

I bought life acces to Rosetta and now the lunch new software and stop improving the other app.

### 1/5 — Motive de dépression

*2026-05-12*

Au début, c'était catastrophique, et à la fin, j'avais l'impression d'être encore au point de départ. Les exercices audio ne reconnaissent pas la voix, même après 500 répetitions avant de faire une erreur, et il faut refaire le même exercice 20 fois pour obtenir la note demandée par l'école (j'ai testé sur 3 appareils et modèles différents, j'ai même essayé de faire les exercices avec des signaux de fumée). Quant à l'écriture, il faut être meilleur que le correcteur orthographique de Word, une IA ou un magicien pour réussir. Je ne le recommanderais même pas à mon pire ennemi, à ma belle-mère, ni à personne que je n'aime pas. Cette application est source de stress, d'anxiété, de dépression et burnout. Merci aux développeurs.

### 1/5 — Настоящая пытка

*2026-04-10*

Я бы никогда не стала пользоваться этим приложением по доброй воле, но пришлось по учебе. Тут ужасно абсолютно все. Начнем с того что просто нереально зайти, а даже если с сотой попытки получилось, молитесь чтобы ничего не вылетело. Темы ужасно составлены, задания кривые, приходится все перепроходить по много раз. Аудирование это просто тушите свет. Там половина букв проглатывается и иногда диктор просто крякает непонятные обрывочные звуки. Проходить эти задания это просто тратить свое время на психозы. НИКОМУ НЕ СОВЕТУЮ.

### 1/5 — Не работает

*2026-01-27*

Ужасное приложение. Одна звезда даже много для такого приложения(

### 1/5 — ARNAQUE

*2026-01-27*

Je me suis faite vider mon compte cpf avec l’arnaque du compte qui expire par cette entreprise NULLISSIME. Cours absolument inutile, application affreuse pleine de bugs. De l’argent jeté par la fenêtre aurait été plus utile. Je suis VERTE. Zéro étoile et j’espère que vous allez couler.

### 1/5 — Ужасное приложение

*2026-01-12*

Отвратительное приложение. Не отображаются пройденные курсы

### 1/5 — Не работает

*2026-01-11*

бессмысленное приложение, работает только сайт

### 1/5 — 很差

*2025-10-27*

非常差的软件，经常有网络问题，同步问题，没有声音等，并且人际交互功能非常差

### 1/5 — Вообще не работает

*2025-10-23*

Отвратительно
