About

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.

What's new

• 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.
