Impressed

Download this if you hate doing math on a jobsite. The UI is intuitive- you just select the conduit type, pick your wire size/type, and hit calculate. It’s scary how accurate it is compared to my manual calculations.

Love the Box Fill add-on. Finally an app that accounts for the volume of the straps and devices, not just the wires. The Reference section is handy for quick lookups without carrying the heavy NEC book around. 10/10, keeping this on my home screen.
