Voluma App

Measure a height with a dipstick: Voluma computes volume, mass and fill % of any tank, for any liquid. View 2D, 3D. A4 PDF gauge chart included.

Voluma turns a simple dipstick height into volume, mass and fill percentage — for any container and any liquid.

No more charts or rough estimates: pick your tank's shape, enter its dimensions, and instantly read the exact volume at the measured height.

EVERY SHAPE • Rectangular box • Vertical and horizontal cylinder • Box with a sloped bottom (different depths) • Box with a sump (deeper bottom) • Free form: define any tank with a height → volume measurement table

FOR EVERY LIQUID Weight comes from density. Give each liquid a colour to spot your fuels at a glance.

CLEAR READING • Volume, mass, percentage and remaining volume • 2D and 3D cross-section faithful to the container's real shape (free camera) • Reading sensitivity: "± 1 mm = ± X" at this level

TWO-WAY Enter a dipstick height OR a known volume (a fill-up receipt, for instance): the other is computed automatically.

CALIBRATION Tune readings to your real container from a known volume.

GAUGE CHART & EXPORT Generate a height → volume chart at the step of your choice, printable as A4 PDF, or export it as CSV. Back up / restore your library as JSON.

YOUR UNITS Volume in liters or gallons (US / imperial), mass in kilograms or pounds, height in cm or mm. Calculations stay exact internally (liters, kilograms).

ICLOUD Your containers, liquids and plans sync across all your devices via your private iCloud.

100% PRIVATE No personal data collected. No trackers, no ads, no third-party accounts. Everything stays on your device and in your private iCloud.

BILINGUAL Interface and numbers fully in French or English.

Voluma is a reading aid with no legal metrological value: the reliability of the result depends on the accuracy of your measurements.
