What it does
Fast where it matters
Built for the moment you have a part in one hand and a phone in the other. No sign-in, no loading, no advertising.
Shows its working
Each result displays the formula and the assumptions behind it, so you can sanity-check it instead of trusting a black box.
Bench-side, so offline
Workshops have bad signal. Everything runs on the device.
Questions
Which standards does the trace width use?
IPC-2221 external and internal trace formulas, with the assumptions shown alongside the result.
Does it replace a proper simulator?
No. It handles the quick checks. Anything that needs real analysis still needs real tools.
Is it free?
Yes, with no subscription.
