SoapCalc Update Log — March 16, 2026 Entry
March 16, 2026 — SoapCalc Is Back. For Real This Time.
Yes, we know the old site said “NEW VERSION COMING IN SUMMER 2021” for about four years. We deserve every bit of grief we got for that.
This time it’s actually here.
SoapCalc has been completely rebuilt from the ground up. The old classic ASP codebase — the one Microsoft stopped supporting two decades ago — is gone. The new site runs on a modern framework with proper hosting, monitoring, and a team that gets notified when something breaks.
What changed:
The calculator works on phones now. The old version cut off half the fields on mobile screens. We’ve tested the new one on iPhones, Android devices, tablets, and every browser we could get our hands on.
Page load time went from 8–10 seconds on a bad day to under 2 seconds.
Every old URL redirects to its new location. Your bookmarks should still work.
We added a status page so the next time something goes wrong — and eventually something will — you’ll have a place to check instead of Googling “is soapcalc down” and landing on a forum thread from 2020.
What didn’t change:
The math. Same SAP values, same oil database, same fatty acid profiles, same INS calculations. If your recipe worked before, it works now. We didn’t touch the numbers.
What we owe you:
An apology for the July 2025 and February 2026 outages with lacking communication. The old server died and we had no way to reach you — no blog, no status page. That won’t happen again. More detail on the status page if you want the full story.
We know a lot of you switched to other calculators while we were gone. Fair enough. We’d like to earn you back, but we’re not going to pretend the competition doesn’t exist. Use what works for you.
Thanks for sticking around. Or welcome back, if you’re just finding out we’re alive again.
