Read full description

Kartt Level makes levelling your campervan quick, accurate and stress‑free. Pair the app with your Kartt Bluetooth level sensor and see your van's exact attitude in real time — front‑to‑back pitch and side‑to‑side roll — on two clear, easy‑to‑read dials. No more guessing with a bubble level or driving back and forth onto ramps. How it works • Two live indicators show your van tilted at its current angle, with the angle in degrees • Each dial tells you precisely how many centimetres to raise a given wheel — or simply says "Perfectly Level" when you're there • Readings update live over Bluetooth LE as you adjust Features • Real‑time pitch and roll from your Kartt sensor • Per‑wheel "raise by X cm" guidance based on your van's measurements • Set Level: zero the sensor to your van's reference position • Adjustable wheelbase distances for accurate centimetre calculations • Choose a van image to match your setup • Quick reset of the level offset • Clean, glanceable display that's readable at a distance Please note: Kartt Level requires a compatible Kartt Bluetooth level sensor to function. The app connects to the sensor over Bluetooth Low Energy; it will not display readings without the hardware. Made for campervan, motorhome and caravan owners by SavvyVan.
