Know how loud it really is — right from your wrist.
dB Meter turns your Apple Watch into a fast, accurate sound level meter. Raise your wrist and instantly see the noise around you in decibels, with a plain-language label so you always know what the number means.
A standalone watchOS app — no iPhone required. It uses the Watch microphone and a per-model calibration so the reading matches what you'd expect.
FEATURES
• Live decibel reading, updated in real time
• Plain-language levels: Almost silent, Normal, Loud, Hearing risk, Dangerous, and more
• Color-coded display that shifts from green to red as it gets louder
• Session Min / Avg / Max so you can track a room over time
• Per-device calibration for an honest reading
• Runs entirely on the Watch — leave your phone in your pocket
• Clean, legible design built for a glance
Great for checking a noisy restaurant, a concert, machinery at work, a sleeping baby's room, or just satisfying your curiosity about how loud the world really is.
Simple app, simple price, no ads, no tracking. Just the number you came for.
Note: dB Meter is intended for general awareness and is not a certified or laboratory-grade sound measurement instrument.
