Level your caravan in one go, without the back-and-forth.
Level Tally pairs with the WitMotion WT9011DCL-BT50 Bluetooth tilt sensor. You fit it once inside your caravan, and every time you arrive on a pitch you get live, accurate readings on your iPhone, on your Apple Watch and in your car with CarPlay.
Millimetres, not degrees
A spirit level tells you you're off. Level Tally tells you what to do about it. Enter your caravan's track width and axle-to-jockey-wheel distance, and the app turns tilt into real instructions: how high a ramp goes under which wheel, and how far to wind the jockey wheel. The same angle needs a different ramp on every van, so Level Tally works it out for yours.
Works with CarPlay
Pull onto the pitch with your caravan's level status on the car's own screen. CarPlay shows side to side and nose to tail, the millimetre correction, and which side or end is low, all titled with your caravan's name. It's a clean, read-only display with nothing to tap, so it's easy to take in at a glance. With your phone connected, audio guidance plays through the car speakers too, so you can hear how close you are as you edge onto the ramps.
Level by ear
Turn on audio guidance and you can stay outside with the van. The beeps follow whichever side you're adjusting and get quicker as you get close. Two quick pips mean side to side is done, one low note means the nose is done, and a chime means you're level and steady. It still plays with your phone on silent, and it mixes with your music instead of stopping it.
Designed for the WT9011DCL-BT50
Level Tally is built around this one sensor and reads its data directly over Bluetooth. Pair it once and it reconnects on its own. Switch the sensor on and the app finds it, even with your phone in your pocket. Battery level is always on show, so the sensor won't go flat halfway through a trip.
No sensor yet? Try it free with your phone
Lay your iPhone or iPad flat in the caravan and the app uses its built-in motion sensors instead. You get the gauge, the guidance and the audio, so you can try it all before you buy any hardware.
Calibration that gets it right
Readings are only as good as your calibration, so Level Tally makes that step hard to get wrong. Calibrate on ground you know is level, or use your phone to measure the slope and remove it for you. You can check your calibration at any time without changing anything.
On your wrist, too
On Apple Watch you get a live bubble with millimetre corrections and complications, so you can see how much is left without walking back to the phone.
More than one van? No problem
Keep a profile for every caravan, each with its own sensor and calibration. Profiles sync across your devices with iCloud.
