What Easyquadtune is, in plain terms

A factual summary for anyone writing about the tool. If a claim is not on this page, please ask before publishing it.

One paragraph

Easyquadtune is a browser and desktop tool that reads a Betaflight blackbox log and produces a tuning report: a step-response measurement per axis, an FFT of gyro and D-term noise, a log-quality score, diagnostics, and a Betaflight CLI block for Cine, Freestyle and Race. It is built by one developer and is not affiliated with Betaflight. The first log is free; further logs are $2.99 each, $9.99 per month or $79.99 per year.

What it claims

It measures the log it is given and shows the definition and confidence behind each number.
It refuses to raise gain on a step chart that is not chart-grade.
It produces a CLI script from the log's own header, with a before/after table for every line.
It keeps the licence key on the device; there is no account.

What it does not claim

That a generated tune is optimal, or safe, for any aircraft other than the one in the log.
That a log can identify a mechanical fault, a failing ESC or a motor temperature problem.
That it replaces a test flight. The report ends with a re-log checklist, not a guarantee.
Any affiliation with Betaflight, PIDtoolbox or Blackbox Explorer.
