Common Questions
Does the app need an account, subscription, or in-app purchase?
No. It is a one-time paid download with no account, advertising, analytics, subscription, or in-app purchase.
Does it work offline?
Yes. Core features and bundled material work without a developer-operated service.
Where is my information stored?
Your editable inputs, imported rows, saved work records, comparison settings, and export history, plus images you deliberately select remain in local app storage.
What are the limits?
Impedance estimates are pre-layout aids. Confirm the final stackup, material properties, copper geometry, fabrication tolerances, field-solver results, and manufacturer guidance.
