STAY LEVEL - CARAVAN LEVELLING APP Stay Level - Caravan Level is an inexpensive way to utilise your existing (Android/Apple) technology to level your caravan. The Stay Level - Caravan Level App connects your two devices be it, Phone to Phone, Phone to Tablet or Tablet to Tablet. For the two devices to connect, they must utilise the same platform, Apple to Apple OR Android to Android. You cannot connect an Apple device to an Android device. Open the App on two devices (with WiFi enabled) and choose display on the device you intend to keep in the vehicle then choose sensor on the device you wish to place in the van on a level surface. Using WiFi connectivity the sensor will transmit the vans level information to the display device in a visual format that is easy to understand. (note that you do not need an internet or data connection) When the van is level in either pitch (front to rear) or roll (side to side) the display will illuminate green to indicate your van is now level on that axis. Stay Level - Caravan Level is ideal for the overnight stays when you want to leave the caravan hitched to the vehicle but still get a good night’s sleep. For the same price as a two way bubble on the "A" Frame draw bar of your caravan you can now download an app that takes the hassle out of levelling your caravan. It’s as simple as “Connect, Level, Relax”
