Mezira: Measure Toolbox

Mezira turns your phone into a small measuring kit. Eight tools use the phone's own sensors, camera and microphone. There is no internet permission, no account, no ads and no subscription. THE TOOLS • Spirit level: on an edge (one axis) or lying flat (two-axis bullseye), slope in percent, hold, set zero against a surface, a short vibration when level • Ruler: centimetres and inches on the screen; calibrate once with a standard-size card or a coin you have measured • Protractor: on the screen, or over the camera image with two arms • Compass: magnetic or true north; the declination is calculated on the phone with the World Magnetic Model (use your location once, roughly, or enter it yourself); warning when metal nearby disturbs the reading • Sound meter: approximate dB(A) with minimum, average and maximum; a correction for your phone can be set; nothing is recorded • Light meter: lux with minimum, average and maximum and plain comparisons (living room, office, cloudy day…) • Metal detector: change in the magnetic field from a baseline, alert threshold with beep or vibration; honest about its limits (iron and steel, a few centimetres away) • Magnifier: camera zoom, flashlight, freeze, high contrast and inverted colours; a frozen image can be shared, nothing is saved to the gallery A tool whose sensor your device lacks is hidden. Reorder the tools or hide the ones you do not use. RECORDS • Save a reading with an optional note; filter by tool • Share as CSV with the system share menu • Backup file you keep yourself PRIVACY • No internet permission: Mezira cannot connect anywhere • Camera and microphone only when you open that tool; images and sound are never saved or sent • Location only once, roughly, only to calculate the declination; only that value is kept All readings are approximate and depend on your phone's sensors. Mezira is not a calibrated measuring instrument and is not for building inspection or safety. Phone and tablet layouts, light and dark theme, 20 languages. One-time purchase: no subscription and no in-app purchases. Mezira, by FigBell — Simple tools. No ads. Just what you need.
