**Your phone is the instrument**The Lab: 101 tools, filtered by group. Spectrum analyzer and compass up top.
**50+ physics simulations**A free Sandbox, then projectile motion, pendulum, spring, collisions, inclined plane.
**Calculate and convert**Solvers for kinematics, energy, SHM, orbits, Ohm's law. A full unit converter.
**A reference library**All 118 elements, colour-coded by family. Constants and 80+ formulas next door.
**Understand every concept**Learn hub: formulas across 10 domains, the periodic table, constants, isotopes, the Standard Model, the EM spectrum.
## Who it's for
### Teachers
Works on whatever phones the class already has. Project the spectrogram and clap.
### Students
Formulas, constants, and simulations to check homework against.
### Makers
Level a shelf, find screws in a wall, check a motor's vibration, meter light in lux.
### The curious
The barometer twitches before rain; the pressure-trend chart shows it happening.
## Measure
- **Sound and DSP**Spectrum analyzer, oscilloscope, spectrogram, tuner, sound-level meter, noise dosimeter, pitch detector, VU meter.
- **Motion and inertia**Accelerometer, G-force, gyroscope, bubble level, inclinometer, seismometer, vibration meter, step counter, free-fall and jump-height timer.
- **Fields and magnetism**Magnetometer, compass, metal detector, EMF detector, dip and field-vector readouts.
- **Environment**Barometer, altimeter, variometer, pressure trend.
- **Light**Lux, EV, foot-candle, daylight.
- **Navigation**GPS speedometer and heading.
## Simulate, solve, convert
### Sandbox
Build a system, tune the physics, watch it run.
### Mechanics, live
Projectile, pendulum, spring, collisions, incline. Change a number and the curve follows.
### Solvers
Leave one quantity blank; it solves for that one.
### Unit converter
Length, mass, speed, temperature, force, energy, pressure, and the rest.
## Look things up
- **Formulas**80+ across 10 domains, sorted by level.
- **Periodic table**118 elements, colour-coded by family.
- **Constants, isotopes, particles**Physical constants, common isotopes and their uses, the Standard Model.
- **EM spectrum**Radio to gamma.
- **Guided experiments**Learn explains the concept behind each instrument. The reaction-time test is a good place to start.
## Practical details
- **9 languages**English, Spanish, French, German, Japanese, Chinese, Arabic, Vietnamese and more.
- **Session log**Go back over your readings later.
- **Offline**No account, no ads, no internet. Readings stay on the phone.
## Free and premium
Free to download. A few advanced simulations are marked premium in the app.
Which instruments you get depends on which sensors your device has.
