Bipi vs Level Tool

OUR STORY Bipi started with a shelf. I wanted to put up a shelf at home and, being on my own, I downloaded a bubble level app. But there were ads everywhere. Then I discovered a bigger problem. While holding the phone under the shelf, I couldn't see the screen. I was trying to level something with a tool I couldn't actually look at. So I thought: what if it could talk to me? I imagined a sound that changed as I moved closer to level, almost like a radar. Then stereo sound made it even easier to understand exactly where I was. That became Bipi. A bubble level designed to be heard, not just seen. HOW IT WORKS Bipi beeps slowly when you are far from level and faster as you get closer. At 0.0° the beeps turn into one steady tone, so you know you are level without looking. WHAT YOU CAN DO • Level surfaces by sound, without looking at the screen • Measure the X axis, the Y axis or both at the same time • Choose a sound guide: Metal Detector, Radar Lock or Stereo • Hear the direction of the tilt in your left or right ear with Stereo sound • Hold a reading and set a target angle • Calibrate on any surface and use it as your new zero • Keep the screen on with Work Mode • Turn on the flashlight in dark corners • Switch to the dark theme GREAT FOR Hanging pictures, mounting TVs, installing shelves, leveling furniture, setting up cameras, caravans and RVs, and DIY projects.

Accuracy depends on your device. • For more accurate results, calibrate Bipi on a surface you know is level. • A thick case or a camera bump can tilt the phone. Calibrate with the case you use. • Bipi is a handy everyday tool. For critical construction work, also check with a professional level.
