XLab Tools

Short description
A screen ruler, digital level, tone generator and sound analysis in one app.

Full description
Measure and explore with four tools on your Android phone. Calibrate the screen ruler, check tilt with the digital level, generate sine, square or triangle tones and run frequency sweeps.

Sound Meter offers live levels, an oscilloscope and an FFT spectrum. Switch views while keeping measurements and controls visible. Read the built-in Help before your first measurement; calibration and session saving have dedicated dialogs.

Save ruler and level readings, tone presets and sound-level sessions locally. Choose a light, dark or system theme and configure screen wakefulness and level haptics. The current development version works offline without an account.

Measurements depend on the phone and calibration. Sound levels are shown in dBFS until a reference adjustment is applied; adjusted SPL remains an estimate. Start generated tones at low volume. Published by Praxis Science Lab.
