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
The beeps get faster as you get closer to level. At 0.0°, you hear one continuous tone. You do not need to look at the screen.
WHAT YOU CAN DO
• Level with sound, without watching the screen
• Choose a sound: Metal Detector, Radar Lock or Stereo
• Stereo shows the direction: sound on the left means it tilts to the left
• Measure on the X axis, the Y axis or both together
• Calibrate any surface as your new zero
• Hold: lock an angle to measure slopes, not only flat surfaces
• Work Mode keeps the screen on and turns on the flashlight
• Dark theme, 18 languages, works offline
GREAT FOR
Hanging pictures, mounting TVs, installing shelves, aligning furniture, setting up cameras, leveling caravans and RVs, DIY and repair work.
