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. WHY IT WORKS dB Pulse: Decibel Meter helps you measure sound, track noise exposure, and save useful records of what you hear.
