## What is Heel Drop?

Heel Drop turns your phone into a real vibration-analysis instrument.
Every FFT spectrum comes from your own accelerometer, computed live.
No external hardware required.

See live time-domain, FFT, and power spectral density views while you
record. Save sessions to a history list with peak frequency and RMS
acceleration. Export raw data to CSV or a professional PDF report.

Every report includes a free comparison against AISC Design Guide 11
walking-excitation limits. This is a simplified reference for engineering
judgment, not a certified compliance calculation. You interpret the
result, same as with any raw instrument reading.

Built for structural and civil engineers, architects, and NVH technicians
doing floor-serviceability checks. Bay slabs, mezzanines, gyms, rooftop
equipment platforms. One phone, one measurement, no setup.

Free tier includes live time-domain and FFT views with peak-frequency
detection, saved sessions, and PDF reports. Heel Drop Pro adds PSD
analysis, velocity and displacement integration, raw CSV export, and
unlimited saved sessions. A phone-level check runs before every recording,
so you know when tilt is contaminating the vertical reading.

Heel Drop reports raw measured data from a consumer-grade accelerometer.
It is not a certified compliance tool and does not replace a licensed
engineer's judgment.
