METRIX — Ruler & Level

METRIX turns your phone into a handy toolkit for everyday measurements.

Need to check if a shelf is straight? Use the built-in leveling tool, which reads your device's accelerometer and shows both a visual indicator and numeric degrees.

Want to measure something on your desk? Place your phone next to it and use the on-screen scale. You can switch between centimeters and inches, and calibrate to your specific screen size for better accuracy.

You can also measure angles with the on-screen arc tool — just drag to set your angle and read the degrees.

Everything works offline with no account required. METRIX doesn't collect any data, has no ads, and all processing stays on your device.

METRIX is part of the Kelthos suite of privacy-first utility apps.
