Trussly Siri Shortcuts feature: 34 construction calculations run as Siri and Shortcuts actions on iOS, and every calculator is searchable in Spotlight. Part of Trussly, the $29.99 one-time iOS construction calculator app with no subscription.

"Hey Siri, calculate concrete with Trussly"

34 calculations run straight from Siri or the Shortcuts app. Siri asks for the numbers, does the math, and reads you the answer. No app to open.

What Siri can do

Concrete volume, footings, piers, block count, studs, rafters, stairs, sheathing, tile, flooring, roof area, shingles, wire size, voltage drop, EV charger circuits, drain slope, gas pipe size, duct size, bathroom fans, paint, drywall, mulch, excavation, and a few more. Ten of them have built-in Siri phrases. The rest show up as actions in the Shortcuts app, where you can name them anything you like.

Siri answers are short. They skip the formula, the code notes, and the warnings you see in the app. For anything structural, electrical, or gas, open the calculator and read the whole result.

Spotlight finds every calculator

Swipe down on your home screen and type "voltage drop." The Trussly calculator shows up in the results. Tap it and you're in. That works for all 85 calculators.
