MechanixCalc
50 ISO/ASME engineering calculators with shareable reports
What this is
Runs 50 ISO/ASME engineering calculators (gears, bearings, bolts, shafts, vessels, welds) in the browser with formulas, worked examples, and exportable branded PDF reports, for engineers instead of $10k desktop software like KISSsoft or MITCalc.
Our one-line summary — not the founder’s tagline.
- How it works
- Each of the 50 tools cites its governing standard, shows the formula and a worked example, and exports a PDF report.
- Pricing
- Free 30-minute preview; no sign-up required.
- Best for
- Engineers needing a standard-cited calculation and a reviewer-ready report without buying desktop suites.

League price & chart
No money. No seat. It goes on your record — and in 28 days reality settles it.
Calls are closed while we rebuild accounts. You can still read every one of them.
Design. Launched 13d ago on Product Hunt, picking up 15 votes. Today, the site itself changed 3d ago — evidence it's still shipping, not just announcing.
Quiet for 3 days — no penalty yet, but quiet doesn't stay free.
We check this site every day, ourselves. A founder can post “still working on it” — a claim like that doesn't price. What we price is what we can verify from the outside: evidence, not announcements. The real question isn't “will this be huge?” — it's “will they still be moving in four weeks?”
The market viewHow this launch is priced and ranked in our league — the investor side of the page.
ranked by the reality anchor, not the market price
It launched on Product Hunt with 15 votes.
No matter how much money goes in. There is no pump here — you can't make yourself right by buying more. The line only moves on things that actually happened: an award, revenue that grew, a new platform, code that shipped — or silence.
6 quiet days in between are left out — nothing happened on them. A launch that goes quiet eases down a little at a time — never a cliff you could have run from the night before.
No names, on purpose — a call is worth what it turns out to be worth, not who made it.
Daily tracking just started for this launch — the first point is on the board. A second reading lands with tomorrow's run, and the curve builds from there.
How the launch is moving on its own board, day by day — the crowd's attention.
A flat line is normal: votes stop within a day or two of launch, on every board. What's unusual — and what actually counts — is a launch that keeps pulling votes long after its day is over.
About
MechanixCalc runs the actual governing standards — ISO 6336 gears, ISO 281 bearings, VDI 2230 bolts, DIN 743 shafts, ASME VIII vessels, EN 1993-1-8 welds and more — in your browser. What's different: every one of the 50 tools cites its standard, shows the formula and a worked example, and exports a branded PDF report a reviewer can follow. It's the bridge between a free single-answer calculator and $10k desktop software like KISSsoft/MITCalc. No install; free 30-min preview, no sign-up.

The board it did best on sets the price. Every other board only adds to it if the launch also placed high on that board too — because just showing up somewhere isn't an achievement. Listing on twelve directories is free; placing well on them isn't.
