New: “How loud is that?” maps everyday sounds onto the decibel scale and pins your live reading in place, so you can see at a glance when it's too loud.
How loud is it, really?
TooLoud turns your iPhone into a simple sound level meter, so you can see at a glance whether the place you're in is loud enough to damage your hearing.
Your ears start to take damage above 85 dB — a busy street, a blender, a noisy restaurant — often without you noticing. TooLoud shows the volume around you in real time and warns you when it's worth reaching for ear protection.
FEATURES
• Live decibel readings — current, average and peak levels at a glance
• A clear, colour-coded meter: green when you're safe, red when you're not
• “How loud is that?” — a reference guide that maps everyday sounds, from a whisper to a concert, onto the decibel scale, with your own reading pinned in place
• Adjustable smoothing to filter out sudden spikes for a steadier average
• A clean, distraction-free design
TooLoud gives guideline readings using your device's built-in microphone, and it's a great way to build awareness of the noise in your daily life.
Protect your hearing — it doesn't grow back.
It doesn't work the way it should it's not accurate, why do we have to select our environment in order to measure the noise .. piece of crap and waste of money
Calibration ability makes all the difference
Retina review
The free version of TooLoud is a toy because the reported values are usually way wrong. Get this version instead to calibrate against a NIST traceable sound pressure level meter and turn your phone into an instrument.
Great for teachers!

I used the old app in my classroom and I'm happy to see the new version. Kids don't know how to monitor their voices during group work and this is a way to teach them to self-regulate. Thanks!
do NOT buy

You have to ‘estimate’ the sound in the room before it will measure it and it affects the level. completely unreliable and inaccurate.
Bug fixes and performance improvements. For real though, to err is human, and i err'd. The app is better now, i promise
