User Reviews

Users praise CLS Review for study help, easy navigation, and helpful explanations, especially for on-the-go review. However, recurring issues across multiple reviews include app crashes (notably on iPad and during larger question sets), upgrade/purchase problems (delayed upgrades or white-screen after purchase), and content shortcomings (repetitive, less challenging questions). Several reviewers also feel the $39 price is too high for what is offered and would like more robust content or features (e.g., more advanced questions, better variation). Stability and value improvements are needed to fully satisfy users.
Pros
  • Helps study and prepares you for lab science exams
  • Easy to navigate with a clean, aesthetic UI
  • Explanations are helpful for understanding concepts
  • Useful for on-the-go practice of questions
Cons
  • Frequent crashes (especially on iPad) during practice or when increasing question count
  • Upgrade/purchase problems (delayed upgrade, white screen after purchase)
  • Repetitive questions and lack of variation; not as challenging as the actual exam
  • Perceived high price for the content; value argument; calls for more robust features
