Noise Recorder - Pro
Decibel Meter & Sound Reports
Free · In‑App Purchases
Measure environmental noise, record audio and video, and create PDF reports you can review and share.
Noise Recorder - Pro combines a decibel meter, audio and video recording, and shareable reports. Keep a record of noise at home, at work or in other everyday settings, then revisit the sound and images whenever you need to.
MEASURE AND RECORD
• See current, minimum, average, and maximum decibel readings.
• Record audio, or capture video with decibel readings and timestamps overlaid.
• Inspect sound-level changes on charts with precise point selection, zooming and panning.
REVIEW AND SHARE
• Browse your recording history, preview saved videos with thumbnails, and play back audio and video.
• Add notes to remember the context of each recording.
• Review daily summaries of your saved recordings, including average and maximum readings, in the noise calendar and monthly charts.
• Find saved recordings by note, decibel range or date.
• Export PDF reports, share audio files, and save recorded videos to Photos.
• Change the app language in Settings and see the interface update immediately.
• Measurements and recordings are saved locally on your device. No app account is required.
FREE AND PRO
The free version includes 3 recordings per day, up to 15 seconds each. Pro removes the daily recording limit and the time limit for individual audio and video recordings. Actual recording duration depends on the storage available on your device.
Choose a monthly subscription for Pro access while your subscription is active, or make a one-time purchase for lifetime Pro access. Both options offer the same Pro recording benefits.
Readings are estimates and may vary with your device and surroundings. The app does not replace a calibrated sound level meter.
