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.
