OUR STORY deBi started with a goal. While watching a big football match, I started wondering how loud a stadium gets when thousands of people celebrate at the same time. Then I thought: why do sound meter apps always look so boring? A number on an empty screen does not tell much of a story. So I imagined a sound meter where the world around you becomes part of the experience. A stadium crowd, a noisy room, a snoring contest, or even a quiet neighborhood. That idea became deBi. A simple sound meter, made a little more fun and a lot more interesting. HOW IT WORKS Open deBi and your camera starts with a live dB meter on the screen. Take a photo or record a video, and the reading is saved inside it. WHAT YOU CAN DO • See the live sound level on your camera, from about 20 to 110 dB • Take photos with the dB reading on the screen • Record videos with the live meter inside the video • Save photos and videos to your gallery automatically • Switch between Analog, VU and Wave meters, even while recording • Use the front or rear camera, in portrait or landscape • Keep a history of your recordings with date, duration and peak dB • Calibrate the microphone by up to ±20 dB • Choose a light or dark theme and use deBi offline GREAT FOR Stadiums, concerts, loud parties, classrooms, workshops and fun sound challenges with friends. FREE VERSION • Live dB meter with the Analog style • Photos, and videos up to 2 minutes • History of your last 20 recordings • No ads of any kind PREMIUM • VU and Wave meters • Videos up to 4 minutes • Unlimited history You can choose a monthly subscription, a yearly subscription or a one-time Lifetime purchase. The yearly subscription starts with a 14-day free trial. This is always your choice. GOOD TO KNOW deBi is made for everyday use and for creating content. Results depend on your phone's microphone and can be different on each device. deBi is not a professional or certified measuring device.
