Everyone has a different trick to set up his motor home or caravan on uneven camping grounds or on the way on pitches horizontally.
Professionals use WomoSet for this - since 2009 !

A correct position of the vehicle is important - otherwise the water in the shower cabin won't run off properly, the stove doesn't work properly, you sleep uncomfortably etc.

iWoMoSet is the first IPhone/iPod touch application that allows you to align the vehicle correctly within seconds. At the touch of a button WomoSet shows you the height of each wheel to be balanced. If you want also with voice announcement on your iPhone or on your Apple Watch.

There is no easier and faster way! A MUST for every motor home fan!
