Layerohm: PCB Stackup

Impedance, loss, thermal vias

$1.99 · Designed for iPad. Not verified for macOS.

Estimate PCB transmission-line impedance offline, compare stackups and tolerances, and keep fabrication assumptions beside every result. Layerohm: PCB Stackup is a focused, fully on-device app. PCB stackup and transmission-line lab for microstrip, stripline, grounded coplanar waveguide, differential pairs, propagation delay, conductor/dielectric loss, and thermal vias. KEY FEATURES - Microstrip impedance sweep - Differential, delay and loss cues - Editable stack records - Local coupon-photo evidence - Editable sample data and CSV import - Side-by-side scenario comparison - Local PDF evidence export - Fifty-three original offline reference plates ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking, or developer-operated backend - Core features and bundled content work offline - Work remains on device unless you deliberately share or export it through an Apple system interface Impedance estimates are pre-layout aids. Confirm the final stackup, material properties, copper geometry, fabrication tolerances, field-solver results, and manufacturer guidance.
