Field Construction Calculator

Field Construction Calculator puts the math you run on every jobsite on your wrist, fully offline. No phone, no signal, no account needed to calculate. EIGHT FIELD CALCULATORS • Slab — concrete volume (length × width × thickness) in m³ and yd³, with a +10% waste figure • Footing — concrete volume for footings and strip foundations • Column — round column / pier volume from diameter and height • Trench — excavation volume for trenches and runs • Area — area and perimeter of a rectangle • Square — diagonal for squaring a layout (3-4-5 check); confirms both diagonals match • Slope — grade as percent, ratio (1:N), and degrees • Fall — drainage fall (drop) over a run, in mm or inches BUILT FOR THE FIELD • Works 100% offline — every calculation runs on the watch • Metric or imperial, switched right on the watch • Results shown in both units at once (e.g. m³ and yd³) • Enter dimensions place-by-place — feet, inches and sixteenths, or metres to the millimetre • Runs on round, rectangular, and Instinct-style screens; touch and button watches alike UNLOCK The app installs from the store. Unlock it with a one-time code from aeviriumstudios.com. Enter the code once on the watch and it stays unlocked. Field estimates only — always verify quantities before ordering material.

• Fixed a crash on Descent MK2 that could stop the app from opening. • Fixed a rare issue that could lock the app after a long stretch with no phone connection — your unlock now stays active offline. • Entering your unlock code while your phone is disconnected now shows a clear connection message instead of a "code not accepted" error.
