Schematic vs Kayf

You live surrounded by systems you can't explain. The breaker panel in the hallway. The boiler that makes a noise you've decided to ignore. The valve someone once told you to find "in case of emergency." Schematic fixes that. HOW IT WORKS Each lesson runs about two minutes. A narrator walks you through a diagram that draws itself as it goes — one card at a time, captioned on screen — and ends with three quick questions so you know it landed. Take one with your coffee, or work through a whole track in an afternoon. WHAT YOU'LL COVER • ELECTRICITY — circuits, volts, amps and ohms, grounding, the third hole in the outlet, and why the breaker trips when the kettle goes on • HOME APPLIANCES — what is actually happening inside the kettle, the fridge, the microwave, the washing machine and the vacuum • PLUMBING — water pressure, P-traps, water heaters, banging pipes, and the shut-off valve you will be glad you found early • ENGINEERING — levers, gears, pulleys, torque, why triangles hold buildings up, and why everything has a frequency it hates NO ACCOUNT NEEDED No sign-up, no profile, no setup. Open it and start. Your progress stays on your device. Schematic is educational. It is here so you understand the systems you live with and can talk about them with confidence. It is not a repair manual, and it is not a substitute for a qualified electrician, plumber or gas engineer.

Kayf is an illustrated encyclopedia of how things work. Pick any device, from the fan on your desk to the refrigerator, the microwave, your phone, a car engine, a wind turbine or an MRI scanner, and open it up. Every one of the 92 devices is a real 3D model, cut open so you can see inside: turn it in your hands, pull it apart, tap any part to learn what it does, and watch the moving parts run. Glowing streams show where the air, water, refrigerant, fuel or current actually goes. Then follow the animated step-by-step sequence of how the device works, with each part lighting up as it plays its role. Place any device on your desk in AR and walk around it at life size. 92 DEVICES IN 8 CATEGORIES - Home appliances: fan, refrigerator, air conditioner, washing machine, vacuum cleaner, water heater, iron, hair dryer, dishwasher, dryer, sewing machine, dehumidifier - Kitchen: microwave, kettle, blender, toaster, espresso machine, induction cooktop, gas stove, pressure cooker, rice cooker, air fryer, oven - Electronics: LED bulb, loudspeaker, microphone, noise-cancelling headphones, camera, television, remote control, lithium battery, electric motor, transformer, smartwatch - Computing and communication: smartphone, touchscreen, Wi-Fi router, processor, SSD and hard drive, printer, GPS, barcode scanner, fiber optics, Bluetooth - Transport: car engine, electric car, bicycle, jet engine, helicopter, how planes fly, ABS brakes, submarine, drone, elevator, escalator, traffic light - Energy: solar panel, wind turbine, hydroelectric dam, nuclear reactor, generator, power grid, gas power plant, desalination, UPS, geothermal - Everyday mechanisms: lock and key, toilet flush, mechanical watch, zipper, bicycle pump, thermostat, smoke detector, doorbell, digital scale, ballpoint pen, aerosol can, fire extinguisher, faucet, 3D printer, power drill - Medical and science: X-ray, MRI, ultrasound, blood pressure monitor, stethoscope, pulse oximeter, infrared thermometer, microscope, pacemaker, defibrillator, telescope FOR EVERY DEVICE - A full 3D model you can turn, zoom, cut away and take apart - Labelled callouts that name every part on the model - Tap a part to learn its role and material - AR mode: stand the device on a real table and look inside it - Animated how-it-works sequence, step by step - The science: several paragraphs on the physics and the design choices - By the numbers: power, speed, temperature, efficiency, lifespan - Surprising facts, types and variants, safety notes - Related devices and the principles they share THE PHYSICS - 36 principles from electromagnetic induction to Bernoulli, each explained with a formula and everyday examples and linked to every device that uses it - A glossary of more than 110 technical terms in plain words KAYF PRO (one-time purchase) - All 92 devices - Troubleshooting guides: real symptoms, likely causes and what to do - Every quiz: five questions per device, category quizzes and the mixed challenge - Compare two devices side by side Made for iPhone and iPad: on iPad a device's 3D model and its explanation sit side by side, in every orientation.
