Rafter & Framing Calc: BuildX
Construction Calculator for Tradespeople
Every trade calculator app I found was either stuck in 2012 design-wise, or a decent tool buried behind a subscription for features that used to just be... the app.
I'm a solo iOS designer/developer, and I kept coming back to the same frustration: construction math (rafters, framing, stairs, board feet, concrete) is genuinely simple once you have the right tool, but every app I tried made it harder than it needed to be — decimal-only input when nobody on a jobsite thinks in decimals, cluttered UI, or a paywall for basic functionality.
So I built Rafter & Framing Calc: BuildX. Fraction-native input (type measurements the way lumber's actually marked), 15 tools in one app, and a one-time $24.99 purchase — no subscription.
It's live on the App Store now. Would genuinely love feedback, especially from anyone in construction/trades — does the fraction input actually feel natural, or am I missing something obvious about how people actually work?

The fraction-native input feels like the real differentiator here. I’d be curious whether that alone changes how quickly someone can use it on an actual jobsite.
