Your journey to
medicine starts here.

A new practice exam type that pulls your overdue review questions first, then tops up with fresh questions from the topics you're struggling with most — no more guessing what to study next before a real test.

Fixed a formula mismatch that could show a different XP total on the leaderboard than on your own Level screen. Both now use the exact same calculation, streaks and all.

Fixed a rare case where an in-progress lesson completion could be lost during background sync, an occasional incorrect Clinical Case score, and improved how quiz results sync back once you're online again.

Breathing mechanics, gas exchange in the alveoli, the nephron, the RAAS cascade, resting and action potentials, partial pressures, and the drug concentration triangle. Every lesson in every module is now fully illustrated — nothing left to draw.

Every lesson now lists the medical textbooks, peer-reviewed papers and health-authority guidelines it draws on — Guyton & Hall, Gray's Anatomy, Alberts, Lehninger, Robbins, Janeway, the WHO and Australian clinical guidelines among them. Check the reasoning behind anything you read.

Study streaks were being counted against UTC, which meant your day rolled over mid-morning. They now track your own local calendar day. Some streak numbers will shift as a result — the new figure is the accurate one.

Tap the version number on your Profile to explore the rest of the range — A Star Math, Science, English and Japanese — each free to download, with no ads. All part of the same family of study apps built with care.
