Help with Filterpole

Getting started, common checks and a direct way to contact support.

Using the app

Choose a filter model, enter its values and check the frequency and unit assumptions.
Set tolerance distributions and requirements before interpreting a simulated yield or envelope.
For a reproducible issue, share a non-confidential JSON project with the app version, expected result and an independent reference calculation.

Before you rely on a result

Filterpole is a modeled design study. It does not replace a circuit simulator, bench measurement, production validation or safety certification.

Include the app name and version, device model, iOS or iPadOS version, what you expected and the steps that reproduce the issue. A small non-confidential example or a redacted screenshot is usually more useful than a full private workspace.

Do not send passwords, API keys, private pairing keys, identifiable health records, confidential reports or other sensitive material. Support does not automatically receive your local app data.
