Phyzix turns your phone into a complete, pocket-sized physics laboratory. Built on the sensors already inside your device, it gives students, teachers, makers and curious minds 100+ real instruments, interactive simulations, calculators and guided experiments - all running entirely on-device. No account. No ads. No internet required. Nothing you measure ever leaves your phone. MEASURE THE REAL WORLD Read live data straight from your device's sensors: - Sound & DSP: spectrum analyzer, oscilloscope, spectrogram, chromatic tuner, sound-level / decibel meter, noise dosimeter, pitch detector, VU meter - Motion & Inertia: accelerometer, G-force meter, gyroscope, bubble level, inclinometer, seismometer, vibration meter, step counter, free-fall & jump-height timer - Fields & Magnetism: magnetometer, compass, metal detector, EMF detector, magnetic dip & field-vector readouts - Environment: barometer, altimeter, variometer, weather-pressure trend - Light & Optics: lux light meter, exposure value (EV), foot-candle and daylight readouts - Navigation: GPS speedometer and heading SIMULATE THE PHYSICS Interactive, parameter-driven simulations you can tweak in real time: projectile motion, pendulums, waves and more - see how the equations actually behave. CALCULATE & CONVERT A full set of physics calculators plus a powerful unit converter for length, mass, force, energy, pressure, speed and beyond. LEARN & EXPERIMENT A built-in Learn hub explains the concept behind every instrument, and guided experiments (like the reaction-time test) turn your phone into a hands-on STEM activity. DESIGNED TO BE USED ANYWHERE - 9 languages: English, Spanish, French, German, Japanese, Chinese, Arabic, Vietnamese and more - Clean, modern interface with light & dark themes - A tool audit log so you can review your sessions and readings - 100% offline and private by design Whether you're teaching a class, checking a measurement, exploring how the world works, or just having fun with the science hiding inside your phone, Phyzix puts an entire lab in your pocket. Note: Available instruments depend on the sensors your specific device includes. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
