User Reviews

Across reviews, the dominant complaints are constant advertising and a heavy pay-to-use model, including unauthorized charges and difficulty canceling. Explanations or results are often paywalled, with questionable question quality and translations cited. Many reviewers view the app as scam-like or greed-driven, though a minority acknowledge the test can be challenging. Overall sentiment is strongly negative due to billing practices and paywalls.

Pros

Cons

Pervasive ads and premium requirement: Free version is ad-heavy and users report ads after almost every question; to access explanations and see results, a pro subscription is pushed.
Unauthorized charges and cancellation problems: Multiple reviews claim being billed monthly without permission and difficulty canceling within the app or via Apple.
Paywalls for explanations and results: Explanations and correct answers are behind a paywall, forcing users to pay to learn or verify answers.
Question quality/translation issues: Some questions have incorrect answers and translations can be confusing or misleading (e.g., metric usage).
Perceived scam/greed and reliability concerns: Several reviews label the app as a scam or greed-driven due to pricing and billing practices.

Recent reviews

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)
