Most weld size calculators out there are buried inside $500 software packages or PDFs that haven't been updated since 2008. I wanted something I could pull up on my phone, punch in a thickness, and get an answer fast with the actual code reference so my QC guy doesn't give me grief. This is the result. Free tier covers the daily stuff: carbon steel, stainless, aluminum, standard joints across AWS D1.1 and ASME B31.3. Pro adds alloys (316L, 6061-T6), PDF reports, and batch history for $9/mo. It's a solo project, so if something's off or you want a joint type added, just tell me. I ship fixes fast.
