Thea review: price, free version and privacy

Our verdict

Thea suits students who want realistic practice tests from their own notes and lectures. Students who need to know exactly what is free, or who prefer not to link location data, should try another study app first.

The description lists adaptive questions that focus on weak spots, flashcards with spaced repetition and game modes, summaries, downloadable study guides and practice tests that simulate exam conditions. It supports over 80 languages and works on phone, tablet and computer.
