Anato vs Open Anatomy Atlas

Anato combines USMLE question practice, study notes, and lessons built around a 3D anatomy model. Its question bank covers Step 1, Step 2 CK, and Step 3 with NBME-style clinical vignettes. Users can work through a question at a time or timed blocks, consult lab values, flag questions, and review explanations. Progress tracking records block scores, time, right and wrong answers, and accuracy by topic and exam step. In the 3D sandbox, users can switch body systems, reveal layers, select structures, and trace nerve and blood supply. Anatomy lesson cards use spaced repetition. Notes are arranged by exam step and subject, with key facts highlighted; gynecology and obstetrics are being written first, with other subjects in progress. An account works on the web, iPhone, and Android, with progress synced between devices. The Free plan uses energy limits and includes bones and muscles in the sandbox plus the first section of each notes book. Pro costs $9.99 a month or $59.99 a year, billed monthly or once a year, and unlocks all questions, notes, sandbox layers, and lessons.
