Wonky van? Not anymore. Wonkometer tells you exactly how much to raise each wheel โ before you've even got the ramps out. No bubble-squinting. No drive-on, drive-off, drive-on again. Just a level van, first time. YOU KNOW THE FEELING You've arrived. The kettle's calling. But the pitch has other ideas โ the fridge won't run properly, the bedroom's on a slope, and you're slowly rolling into your partner. Again. There's a better way, and it takes about thirty seconds. LEVEL IN THREE STEPS 1. Fit it once โ Mount the Wonkometer sensor anywhere in your van and calibrate with one tap on level ground. Setup done, forever. 2. Pull onto your pitch โ Open the free app and it connects automatically over Bluetooth. 3. Do what it says โ "Raise right by 10cm." Put the ramp in, drive on, and the app confirms when you're perfectly level. Kettle on. IT DOES THE MATHS SO YOU DON'T HAVE TO Every other level gadget tells you THAT you're wonky. The Wonkometer tells you WHAT TO DO about it โ in centimetres, per wheel. Tell the app your wheel distance once and it converts tilt angle into exact ramp height. One drive onto the ramp. Level, every time. CAMPERVAN, MOTORHOME OR CARAVAN โ IT SPEAKS THEM ALL Choose your vehicle in the app and the Wonkometer shows your actual setup โ caravan owners get front-and-side views, van and motorhome owners get the full side profile. Same little sensor, every kind of wonk. SMALL BOX. BIG BRAIN. - Exact ramp heights โ per-wheel instructions in centimetres, not vague arrows - 30-second setup โ one-tap calibration on level ground, done for good - Bluetooth, no faff โ connects automatically when you arrive on pitch - Any vehicle โ campervans, motorhomes and caravans - No Wi-Fi or signal needed โ direct Bluetooth between sensor and phone, works in the remotest corner of the remotest site - Free app, free updates โ new features land automatically - Reads tilt to within a single degree โ tighter than any bubble you'd squint at FREE. NO NONSENSE. No subscription, no ads, no nonsense. The app is free, and so are the updates. CHANGING VANS? Take it with you. Re-mount, recalibrate with one tap, update your wheel distance, carry on. BUILT BY SAVVYVAN The Wonkometer is built in the UK by SavvyVan โ makers of bespoke touchscreen control panels and software for campervans. Already have a SavvyVan system? It integrates hand-in-glove, so levelling becomes just another thing your van quietly takes care of. Banish the wonk. Requires the Wonkometer Bluetooth sensor, available at www.wonkometer.com
