Ever needed to level your caravan or autocamper? Tired of running back and forth to check if you're perfectly level? Caravan Leveler turns your iPhone into a precision leveling sensor. Place your phone on a flat surface inside, then monitor the live level remotely — from your Apple Watch, a second iPhone, or an iPad — using peer-to-peer connectivity. No Wi-Fi or internet required. ONE APP, BOTH KINDS OF VEHICLE - Caravan: wind the front up or down on the jockey wheel and chock a side — the app tells you which way and how far - Autocamper / motorhome: it knows you can only drive onto ramps, so it never asks you to lower something that cannot be lowered. It names the wheels to raise and by how much - And when the ground is simply too steep for ramps, it says so instead of quoting a number no ramp can reach - Choose your vehicle once during setup; a second device or Apple Watch follows automatically DRIVE-ON GUIDANCE - Audible guidance beeps faster as you approach level and chimes when you arrive - Keep your eyes on the ramps instead of the screen while you creep into position - Ducks your music or radio rather than stopping it MULTIPLE WAYS TO VIEW YOUR LEVEL - Vehicle silhouette: see your caravan or motorhome from the front and side with real-time tilt angles - Bubble level: a classic 2D spirit-level bubble that responds to every adjustment - Combined view: both displays at once for maximum confidence MULTI-DEVICE LEVELING - Sensor mode: your device reads the motion sensors and broadcasts the live level - Display mode: a second iPhone or iPad connects peer-to-peer and mirrors the level in real time - Apple Watch: see the level straight from your wrist while you adjust the corner steadies - Works offline — no Wi-Fi, no internet, no account needed KNOW HOW MUCH TO RAISE - Enter your wheel spacing and jockey-wheel distance or wheelbase for precise raise estimates - The app corrects side to side first, then front to back — the order that actually works - Calibrate on any uneven surface with a single hold gesture SUN DIRECTION INDICATOR - See which way the sun is shining relative to your vehicle - Park for shade or solar gain — works anywhere in the world SPEAKS YOUR LANGUAGE - English, Danish, German, Dutch, Norwegian and Swedish SIRI & SHORTCUTS - Switch vehicle type, toggle drive-on guidance, change mode, and calibrate — all hands-free FLEXIBLE ACCESS - Try the app with a Week Pass or Season Pass - Go all-in with an Annual Premium subscription Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
