dB Pulse: Decibel Meter

Track noise, save sessions, and get alerts when sound stays too loud. Add widgets, use Quick Measure, and ask Siri for the current decibel reading. No account required.

Stop guessing if a room is too loud. Check the current noise level in seconds, track your daily noise dose, and get alerts when sound stays over your limit.

WHAT IT DOES

• Measure live decibel levels with a clear meter you can check at a glance.
• Start Quick Measure from the Home Screen for a 5-second snapshot when you need a quick noise reading.
• Keep a Live Activity running while metering so the current decibel level stays visible on the Lock Screen.
• Add Home Screen and Lock Screen widgets to see your latest noise level without opening the app.
• Track your Daily Noise Dose with a 7-day sparkline so it is easier to spot louder days.
• Set sustained-noise alarms to alert you when sound remains above your chosen level.
• Copy the current dB reading with one tap when you want to paste it into a message or note.
• Save session history so your recordings stay available across app launches.
• Export session data as a shareable table, with free users able to export a limited number of sessions.
• Ask Siri things like what the noise level is, hear the current reading spoken aloud, or run Quick Measure hands-free.
• Calibrate the meter with a reference tone walkthrough when you want readings matched to your reference setup.
• Capture and share photos with a live noise level overlay.

PERFECT FOR

• Checking whether a bedroom or nursery stays quiet enough at night with a sustained-noise alarm.
• Taking a quick sound meter reading in a classroom, office, restaurant, or workshop with Quick Measure.
• Watching your daily noise dose after commuting, attending events, or spending time around power tools.
• Saving a session during rehearsal, practice, or venue setup and sharing the results afterward.
• Keeping the current decibel reading visible from widgets or the Lock Screen while you move around.
