Wonkometer app on a phone in campervan mode showing level on the side axis at 0 degrees and the front view at minus 5 degrees with instruction Raise left by 9cm

Wonky van? Not anymore.

Wonkometer tells you exactly how much to raise each wheel — 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 — the fridge won't run properly, the bedroom's on a slope, and you're lying in bed slowly rolling into your partner. Again. So out come the ramps: drive on, jump out, squint at a bubble, not quite, drive off, adjust, repeat. There's a better way, and it takes about thirty seconds.

Level in three steps

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 — 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.

Questions? Wonk no further.

Will it work with my van/caravan/motorhome?

Yes — choose your vehicle type in the app and it adapts the display and instructions to match. Campervans, motorhomes, caravans and trailers all speak fluent Wonkometer.

How do I use it?

Fit the sensor somewhere dry inside the vehicle, pair the free app, tap Set Level on level ground, give it your wheel distances and pick your vehicle. After that it's just: park, open the app, do what it says. The full walkthrough lives in the user guide.

How accurate is it?

The sensor reads your tilt to within a single degree — tighter than any bubble you'd squint at, and comfortably level enough for happy fridges, flat beds and spill-free brews.

Do I need Wi-Fi or signal?

No — direct Bluetooth between sensor and phone. Works in the remotest corner of the remotest site.

Is the app really free?

Yes. No subscription, no ads, no nonsense.

What if I change vans?

Take it with you. Re-mount, recalibrate (one tap), update your wheel distance, carry on.

I already have a SavvyVan system — does it integrate?

Yes — it's built by the same team, on purpose. The Wonkometer works hand-in-glove with your SavvyVan system, so levelling becomes just another thing your van quietly takes care of. See more at www.savvyvan.com
