## NoiseLedger Description
NoiseLedger is a privacy-first sound level meter and noise history log for iPhone. Use it to check room noise, track office sound levels, and export clear reports without ads, accounts, or cloud tracking.

Measure sound level in real time with FAST or SLOW response, watch MIN / LEQ / MAX values, and open the FFT spectrum view to inspect peak frequency. When you want to keep a record, save a session with a title, tag, note, and markers, then review it later in History.

Why people will use NoiseLedger:
- Quick noise level checks at home, in the office, or in an apartment
- Session history for comparing repeated measurements over time
- PNG report and CSV export for sharing or archiving results
- Calibration offset and A- or Z-weighting for more useful readings
- Offline-first design with no ads, no account, and no audio storage

Important accuracy note:
NoiseLedger uses the built-in smartphone microphone, so readings are approximate and can vary by device. Raw audio is processed in real time and is never recorded or stored. For legal, workplace compliance, or safety-critical measurements, use a calibrated Class 1 or Class 2 sound level meter.
