User Reviews

LumiSource is praised for being free, ad-free, and easy to use, with a broad set of AP study materials and practice questions that many users credit for exam prep success. Reviewers highlight the accessible UI and vast content across AP subjects as strengths. However, several reviews note content gaps: many APs aren’t available yet or opened. Some also want features from the website in the app, such as in‑app definitions or explanations. Overall it’s a strong, free study tool with room to expand coverage and align features with the site.

The app is easy to use and I would use it if they didn’t have you study for information that you don’t don’t to know. Wasted my time learning about things I didn’t even need to know for the exam.
