When a new peak reading is set, a 15-second audio clip is recorded and attached to your session report. Audio is stored locally only — never transmitted. Opt-in only. For ECHR Art. 8 filings, a clip at the moment of exceedance significantly strengthens evidentiary value.
Measure the same noise event from multiple phones simultaneously. Create a session and share the code with others nearby.
