LevelVan: Level Your Camper

LevelVan tells you which wheel to raise and by how many centimetres. Not an angle you have to convert first.

Put the iPhone on the dashboard, start "Level", drive slowly onto the ramp. The instruction updates live and reads from two metres away, so your eyes can stay on the mirror.

HOW IT WORKS

1. Add your vehicle. Enter wheelbase and track width: that is what turns a tilt into a real height in centimetres. One degree means something different on a panel van than on a caravan.

2. Add your ramps. Enter the real step heights of your levelling ramps. LevelVan then names the stage to use, instead of handing you a number you would have to translate to your own ramps.

3. Level. One wheel, one instruction, one number. Colour and word say the same thing, so the state is clear even with sun on the display.

CALIBRATE ONCE

Every iPhone has a small sensor error, and the camera bump tilts the device on top of that. LevelVan measures both away: place it, turn it 180 degrees, done. The app takes the samples itself as soon as the device rests still: no buttons, no shaky readings. If the measured error is implausible, LevelVan says so instead of storing it.

FREE

Levelling itself stays free, with one vehicle and one ramp profile. No ads, no account, no sign-up.
