Orbit a semi-transparent body and tap any organ to see what it's for, which system it belongs to, and a real clinical fact that makes it stick. Switch between systems, drill into the real blood vessels or a heart's chambers, and fade the body away. Anatomically-accurate models; works on any phone.

Tap any tooth on an interactive chart to learn its name, numbering, and job — plus a real dental fact. Then explore a labelled cross-section from the rock-hard enamel down to the living pulp.

Spin a 3D double helix, then set each parent's genes and watch a Punnett square show every trait a child could inherit — a simple, honest intro to genetics.

Ten questions on your body — name the organ, the system it belongs to, and its job, plus a few fun facts drawn from across this section. Recalling from memory is how it sticks; jump from any answer straight to it in the 3D Human Body.

Watch your body's systems work in real 3D: a beating heart with its rate and blood pressure, breathing lungs, your nervous system (test your reaction time) and blood-sugar control after a meal. Pick a system, drag the effort slider from resting to sprinting, and jump to its anatomy in the 3D Human Body.

Take a bite and follow it from mouth to exit — the real time it spends in your stomach and intestines, and what happens at each stop. Your gut is ~9 metres long and does it all without you thinking.

Bend an elbow and watch its biceps and triceps trade off — one contracts to pull the bone, the other relaxes and stretches. See why a muscle can never push, so they must work in opposing pairs, and how a fibre actually shortens.

Move a real shoulder, elbow, forearm, wrist and thumb through their true range of motion. Each joint gets one dial per axis of freedom — a hinge has one, a wrist two, a shoulder three — so you can see at a glance why a ball-and-socket roams and a hinge is strict. Turn on the anatomy layer and watch a ligament pull taut at the limit.

Play a real tone and slide it to the very edge of your hearing, then move an object near and far and watch an eye change its lens to stay sharp — with what age, short-sightedness and loud noise really do.

Build a plate from common foods and watch the calories and the protein / carb / fat / fibre add up — with a plain-English guide to the macros and a balanced plate.

Even at rest your organs burn ~1,500 kcal a day — see where they go, then pick an activity level and watch the daily total climb. The plain truth about metabolism.

Pick a cancer to see, in 3D, the organ where it begins — what it is, the signs it can cause, how it's found and treated, and an honest, hopeful word on outlook and support. 16 of the most common cancers.

A plain-English intro to first aid and a CPR-rhythm trainer, following Red Cross / AHA guidance — practise the 100–120/min beat and learn the priorities. A learning tool, not emergency instructions; please take a real course.
