IN THE LAB TODAY

Six tools, one tiny app

Independent mini tools, one lightweight app. More are coming — the app grows with every release.

Color Palette

Random or color-wheel-harmonic palettes, 2 to 10 colors each. Every color gets its human name — from a dictionary of almost 5,000 named colors — a tap-to-copy HEX code, and a lock to keep the ones you like while rerolling the rest.

Password Lab

Strong random passwords — length 8–64, configurable character classes, ambiguous-character filter — and Italian diceware-style passphrases, with an honest entropy meter. Generated on your device, never stored.

Bubble Level

A pocket spirit level driven by the tilt sensor: circular dial, per-axis degrees, zero calibration on any reference surface, and a hold button to freeze the reading.

Sound Lab

A tone generator with four waveforms — sine, square, sawtooth, triangle — a logarithmic frequency slider from 20 Hz to 20 kHz with musical note readout, and a theremin pad: slide your finger to glide pitch and volume in real time.

Stat Lab

The classic probability distributions — normal, uniform, exponential, Poisson, binomial — explained by playing with them: move the parameters, watch the curve, then draw random samples and see the histogram converge to the theory.

Doodle Lab

Draw a quick sketch and a tiny neural network running entirely on your phone guesses what it is among 40 categories. Challenge mode picks a subject and scores you when it recognises your drawing. Trained on Google's Quick, Draw! dataset (CC BY 4.0); no internet, ever.
