Version 1.2Thu Sep 17 2026
Content accuracy pass across all 14 body systems, plus new ways to study and several bug fixes:
-Added Content to Learn — now contains the full education course content
- Added Study Cards — a shuffled flashcard deck pulled from every quiz question and Learn chapter
- Added References — the physiology textbooks this content is written and checked against
- Added a How to Play guide covering hearts, XP, ranks, and all four level types
- About & Terms is now a clearly labeled link on the home screen, with an expanded Terms of Service and a dedicated liability/non-affiliation section
- Fixed Case Boss occasionally costing an extra heart when you tapped an already-wrong answer again
- Fixed the boss health bar's number counting the wrong direction from the bar itself
- Fixed the Sim Target gauges (heart rate/MAP, ventilation, GFR, acid-base) to show the full range as you adjust the sliders, instead of pinning early
- Corrected wording on the oxygen-hemoglobin curve's Bohr effect, a clinical case's blood-gas values, and an exercise-physiology explanation about coronary blood flow
- Bigger tap targets and added accessibility labels on navigation buttons throughout
- Under-the-hood reliability fix so saved progress survives future content updates
Requires iOS 15.0 or later. Compatible with iPhone, iPad, and iPod touch.
A learn and game-style path through human physiology — 14 systems, 44 levels, and four mini-games. Learn the body's mechanisms, then master them. Built for med & pre-med.
Physiology Arena turns a full physiology course into a game you'll want to keep playing.
A PATH THROUGH THE WHOLE BODY
Follow a map of 14 body systems and 59 levels — Cells & Homeostasis, Nervous System, Muscle, Cardiovascular, Respiratory, Blood & Gas Transport, Renal, Endocrine, Gastrointestinal, Fluids & Acid–Base, Reproductive, Thermoregulation, Exercise Physiology, and Sensory Physiology. Each level teaches a real mechanism, at the depth of a medical-school physiology course.
READ IT, THEN MASTER IT
Learn mode is a built-in study guide with one chapter per system — 14 in all. Open any chapter to read a clear, exam-focused breakdown of its mechanisms — control loops, membrane potentials, cardiac output, the oxygen–hemoglobin curve, acid–base balance, the HPG axis, thermoregulatory set points, and more — then jump straight into that system's levels to test yourself.
FOUR WAYS TO PLAY
- Quiz Rush — fast multiple-choice with combos and explanations
- Label Lab — tap-to-label anatomy and diagrams
- Sim Target — interactive physics models (pressure gauges, the oxygen–hemoglobin curve, the action potential)
- Case Boss — branching clinical cases with an HP bar
STUDY YOUR WAY
Study Cards shuffle a flashcard deck pulled from every quiz question and Learn chapter — flip to reveal, then move on. References lists the physiology textbooks this content is written and checked against. And How to Play walks through hearts, XP, ranks, and all four level types.
PROGRESS THAT STICKS
Earn XP and climb ranks, keep a daily streak, spend coins, and manage hearts as you clear each system. Every answer comes with a clear explanation, so a miss still teaches you something.
BUILT FOR MED & PRE-MED
Written for students heading into medicine — the mechanisms that matter in the clinic, from membrane potentials to acid–base balance to the HPG axis, made interactive.
