Turn your iPhone into a precise sound-level companion. Measure ambient noise in dB with A-weighting and fast/slow time weighting. Start a session in one tap, tag a place, and watch live levels on a clean graph. Save sessions for Home, Office, Metro, Park, or your own labels. Each session stores Leq, Max, Median, and the share of time above your alert threshold. Trim the range to focus on the moments that matter and export CSV for deeper analysis.
Smart detection highlights events such as sirens, doors, or renovations and shows their peak levels with timestamps. Calibrate with an offset to align readings to an external reference. Set your own threshold and optional haptic warnings to stay aware without watching the screen.
Analytics reveal trends across days and locations, so you can spot patterns, compare rooms, and make safer choices for your hearing. No account is required; data stays on device until you export. Designed for clarity, speed, and low power use.
Whether you’re tuning a workspace, checking a nursery, or logging city noise, this tool helps you measure, understand, and act.
