- Current level
- Large, glanceable live reading
- Session detail
- Min, max, average, Leq and peak
- Audio handling
- Processed on device, never saved
- Measurement class
- Consumer estimate, not certified
01 · Full-screen monitor
The reading stays in command.
Turn the phone sideways for a wide, distraction-free instrument with gauge, graph or number-only layouts. Min, max and Leq remain visible while the session continues.
02 · Selectable instruments
One meter. Three physical personalities.
Choose a dark precision instrument, a warm studio VU face or a compact field meter. The measurement stays consistent while the instrument changes around it.
03 · Sessions and reports
A measurement you can revisit.
Record timestamped sound-level samples, add an optional name, location label or notes, then review the graph and summary later.
Useful session context
- Minimum, maximum, arithmetic average, Leq, peak, range and duration.
- Weighting, response, device profile and microphone route history.
- User-initiated PDF, PNG and CSV sharing.
Local by default
The newest 50 sessions stay in protected app storage. The app does not upload saved-session content, and raw microphone audio is never stored.
04 · Trust boundaries
Clear about what the phone can measure—and what it cannot certify.
- Microphone
- Used while measuring. Raw audio is not saved, uploaded or shared.
- Diagnostics
- Optional pseudonymous Firebase diagnostics are off until the user opts in.
- Deletion
- Delete individual sessions or use Delete all local data inside the app.
- Accuracy
- Results are consumer estimates affected by the microphone, route, case, processing and position.
05 · Cross-platform
A native measurement path on every platform.
The interface is shared, while time-critical microphone capture and signal processing stay behind native Android/Huawei and iOS boundaries.
- Android
- iOS
- Huawei
Built for practical monitoring
Switch A, C or Z weighting and Fast, Slow or Impulse response. Inspect the active microphone route, clipping and automatic device estimate before relying on a reading.
Not a legal instrument
