SteelFlow

SteelFlow is an offline-first iPhone and iPad app for metal-weight calculations, fabrication estimates, and client-ready quotes.

Calculate plate, bar, tube, angle, channel, I/H section, and custom-section weight.
Use metric or imperial dimensions with built-in or custom material densities.
Track material prices, waste, processing fees, markup or margin, and tax.
Organize estimates into projects and export PDF quotes or CSV material lists.
Back up and restore your local SteelFlow data without creating an account.

Project, supplier, company, and quote data stays on your device unless you explicitly export or share a file.
