Tank Volume Log vs Everwhen

Tank Volume Log turns tank dimensions and field measurements into clear liquid volume results on iPhone and iPad. Enter a Dip or Ullage reading, choose your units, and see liquid volume, total capacity, remaining capacity, resolved liquid level, and fill percentage in one place. Use a built-in geometry or your own calibration table for repeatable tank-specific work. CALCULATE FOR 10 TANK MODELS - Vertical cylinder - Horizontal cylinder - Rectangular tank - Spherical tank - Horizontal capsule - Vertical capsule - Horizontal elliptical tank - Cone-bottom cylinder - Conical frustum - Custom level-to-volume calibration table MEASURE THE WAY YOU WORK - Switch between Dip and Ullage - Set a reference height for Ullage calculations - Use Metric or US Customary presets, then customize individual units - Choose millimeters, centimeters, meters, inches, or feet - View liters, cubic meters, US gallons, Imperial gallons, or oil barrels - Enter decimal inches or tape-style fractions at 1/8, 1/16, or 1/32 precision SEE MORE THAN ONE NUMBER - Liquid volume after optional water deduction - Total and remaining capacity - Resolved liquid level and fill percentage - Optional weight from entered liquid density - Visual fill gauge for at-a-glance checking REUSE TANKS AND RECORDS With Lifetime Access, save tank dimensions, a default Dip/Ullage mode, reference height, and optional density. Reopen a saved tank for the next reading, search your tank list, and review recent calculations. IMPORT CALIBRATION TABLES Create a table manually or import CSV/TSV data. Choose Innage or Ullage basis, source units, and decimal format. Tank Volume Log validates the file and interpolates between the level-volume points you provide. KEEP AND EXPORT YOUR WORK Save calculations, search by tank or shape, filter All Time, the last 30 days, or This Year, and open each result with its inputs. Export filtered records as CSV or PDF, or share a single calculation as a PDF. Quick results can also be copied or shared as text.
