Why Tidox Sound Meter
Accurate, readable noise measurement — all on your device, zero data sent to the cloud.
Live Readings
Watch sound levels move in real time as the world gets louder and quieter around you. Instant response, no lag.
Peak & SPL
Beyond the moment: track peak levels and SPL so you know how loud it really got — and whether it stayed there.
Readable Gauge
A clean gauge you can read at arm's length, with reference points that tell you what the numbers mean for your ears.
Measure Anything
Office hum, traffic, a club, your kid's drum practice — point your phone and know the number in seconds.
Fully Offline
Your microphone data is processed entirely on-device and never recorded or uploaded. Measure freely, anywhere.
Privacy-First Design
No accounts required, no data collection, no ad tracking. A measurement tool should never listen for anyone but you.
