Features
What it does
- Instant sound level readings from the wrist, with no phone involved
- Useful anywhere you would otherwise guess: gigs, workshops, city streets, open-plan offices
- Discreet enough to check without making a performance of it
- Designed for a quick glance rather than a lab report
Do I need my iPhone?
Not while you are using it. This is a standalone watchOS app: it runs on the Apple Watch on its own, with the phone switched off or left behind. You do need an iPhone once, to purchase and install it — that is an App Store rule rather than anything about this app.
FAQ
Questions
Something else? Ask me directly .
How accurate is it?
It is a consumer-grade reading from the watch microphone, good for comparing environments and spotting genuinely dangerous levels. It is not a calibrated Class 1 sound level meter and should not be used for compliance work.
How loud is too loud?
As a rough guide, sustained exposure above 85 dB carries risk, and the safe exposure time roughly halves for every 3 dB above that.
Do I need my iPhone?
No.
Does it log readings over time?
It is built for instant readings rather than continuous logging.
