Physiology by Reason
Every answer choice, explained
$24.99 · Designed for iPad. Not verified for macOS.
958 questions from more than thirty years of Japan's national exams, in textbook chapter order. A reason for every choice, so the mechanism stays with you.
That answer choice: why is it right, and why are the others wrong?
Physiology falls apart when it is memorized. Facilitates or inhibits, rises or falls: one reworded line and a question you thought you knew is gone. Learn the mechanism and even an unfamiliar question has a route to the answer.
Physiology by Reason is a question bank with a reason for every answer choice. Answer a four-choice question and the app tells you at once whether you were right, then explains why each choice is correct and why each of the others is wrong.
WHAT IS INSIDE
958 questions across 15 chapters and 70 sections: foundations of physiology, blood and circulation, respiration, digestion and absorption, metabolism, body temperature, renal and endocrine physiology, reproduction and aging, neurophysiology, muscle, motor control, sensation, and body defenses.
The questions come from more than thirty years of a national board (1993 to 2026), translated and reordered to follow the chapters and sections of a standard anatomy and physiology course, so working through the bank in order is close to reading a textbook straight through.
Every question carries an Explanation, Key points with a Memory hook, and, on most questions, an At a glance table that sets the pairs that cost marks side by side.
HOW YOU LEARN
Smart review. The app picks what you should see today, scheduled by a modern spaced-repetition algorithm, so a question returns just before you would forget it. Reviews only, new plus reviews, or everything.
Study by chapter and section. One topic at a time, with a progress bar for every chapter.
Read by contents. Read a chapter straight through the way you read a book: question, answer, full explanation, in order.
Search. Full-text search takes you from a term to every question that touches it: a reference as well as a drill.
Bookmarks and lists. Flag what keeps catching you out and build your own weak-points notebook.
Export. Any selection of questions as Markdown, rich text (RTF) or PDF, or straight to the printer.
Stats. Study streak, accuracy, progress by chapter, and what is coming up for review.
Today's tip. A morning note: yesterday in a line, one piece of advice from the science of learning, and a countdown to your exam.
Exam date. Set the date you are working toward and the app paces the daily target around it.
Text scales up to extra large, and iCloud sync keeps iPhone and iPad on the same page.
WHO IT IS FOR
For students of massage therapy, acupuncture, physical and occupational therapy, chiropractic and kinesiology, and for anyone in a first or second year A&P course, including pre-nursing and pre-med.
OUR HONEST-CARD POLICY
We write a reason for every answer choice, one question at a time. Having promised that, we owe you a second piece of honesty: however much care goes in, a few errors can remain, and we do not hide it. Every explanation ends with a Report a correction button that fills in the question for you. We read every report, fix what needs fixing, and ship it in an update.
PRIVACY AND PRICE
A one-time purchase. No subscriptions, no in-app purchases, no advertising, no tracking, no account. Your study records stay on your device and travel only through your own iCloud account if you turn sync on.
