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 โ€” a busy street, a blender, a noisy restaurant โ€” 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 โ€ข Live decibel readings โ€” current, average and peak levels at a glance โ€ข A clear, colour-coded meter: green when you're safe, red when you're not โ€ข โ€œHow loud is that?โ€ โ€” a reference guide that maps everyday sounds, from a whisper to a concert, onto the decibel scale, with your own reading pinned in place โ€ข Adjustable smoothing to filter out sudden spikes for a steadier average โ€ข 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 โ€” it doesn't grow back.

Cobalt Link+ is a flexible, cross-platform screen sharing and remote control solution.

Communication between the display device and the mobile device may be conducted either wirelessly or via USB cable. Simply pairing them over Bluetooth is usually the first stage, or plugging a compatible cable from the display into your devices charging port.
