IYI rate beter than you

Pas au point

Certains résultats justes ne sont pas validés,
Des énoncés sont en espagnol, certaine traductions en français sont des non-sens. Il est difficile d’entrer 2
Chiffres dans les réponses car l’espace n’existe pas. Bref cette app est extrêmement décevante.

Many errors

I only recommend the free version of the app due to the number of errors. Sometimes there are wrong answers (especially on vocab Qs). But sometimes there’s a typo such as “answer for the question mark,” but there’s no question mark in the prompt… The app was clearly not made by a native English speaker, which is fine except where it interferes with accuracy, (which feels important for this kind of app)
