What it does
Park anywhere, open the Leveler, and you'll see a top-down view of your rig with a number under each wheel — how much that corner needs to be lifted to bring everything level. The lowest corner is the reference and reads 0.0. Chock the other three to match.
It works for anything with four wheels: RVs, vans, camper trailers, even your truck if you're trying to sleep flat in the bed.
Setting up your rig Pro
Before the Leveler can calculate corner offsets, it needs two measurements from your vehicle:
- Wheelbase — distance from the centre of the front axle to the centre of the rear axle, in centimetres.
- Track width — distance from the centre of the left wheel to the centre of the right wheel, in centimetres.
You only do this once per vehicle. To enter them:
- Open your Garage and tap the vehicle.
- Tap Edit.
- Scroll to the Dimensions section. Wheelbase and Track Width are at the bottom.
- Enter both values and save.
If you skip this and try to open the Leveler, you'll get a friendly prompt that sends you back to Edit.
Finding your wheelbase and track width
The owner's manual is the easiest source — both numbers are usually in the spec sheet. Failing that:
- Manufacturer's website — search "[year] [make] [model] wheelbase" and "[year] [make] [model] track width". Major manufacturers publish these.
- Measure it — a tape measure from the centre of one hub to the centre of the next. Get someone to hold the zero end. For wheelbase, run along the side of the vehicle. For track width, run between the two wheels on the same axle.
- RVs and motorhomes — check the chassis sticker inside a cabinet door or near the driver's seat. Manufacturers often list both there.
Precision isn't critical — a centimetre or two off is fine. The Leveler is calculating relative corner heights, not absolute distances, so small measurement errors mostly cancel out.
Using the Leveler
- From the vehicle's Garage page, tap the orange Level this rig → button. The Leveler takes over the full screen.
- Set your phone flat on a stable surface inside the rig — dashboard, dinette, kitchen counter. Anywhere that's rigidly attached to the chassis.
- Read the four corner values. The corner reading
0.0with the orange highlight is the reference — leave it alone. Lift the other three to match. - When all four corners are within half a unit of each other, the screen pulses green, the badge reads LEVEL, and you'll hear a single beep.
The screen stays awake while the Leveler is open, so you can set the phone down, chock the corners, and check the readings without unlocking.
Zero, Lock, and Reference
Three controls under the main display:
- Zero — calibrates the current attitude as "level". Use this if you're trying to level the rig relative to itself (already-tilted starting position) rather than to true horizontal. Tap again to un-zero.
- Lock — freezes the displayed wheel offsets so you can move the phone, set it down, or walk outside to place blocks without the numbers changing. Tap again to unlock and read live.
- Reference (in Settings) — by default the Leveler picks the lowest corner as the reference automatically. If you'd rather anchor to a specific wheel (say, the one closest to a curb or fence that can't be raised), pick FL, FR, RL, or RR in the Settings drawer.
Units and smoothing
In Settings you can toggle:
- Units — centimetres or inches. The numbers are recalculated on the fly; your stored dimensions stay in cm regardless.
- Smoothing — applies a low-pass filter so the readings don't flicker on every tiny phone movement. On by default. Turn it off if you want raw, twitchy readings (useful when you're already close to level and want to see micro-adjustments).
Both preferences are saved per vehicle — the diesel pusher and the Tacoma can have different setups.
iPhone & iPad: motion permission
The first time you open the Leveler on iOS, you'll see a panel asking to Allow motion access. iOS requires this for every app that reads tilt sensors. Tap it once, grant permission, and you're set for the session. If you accidentally deny, you can re-enable motion access in Settings → Safari (or Settings → ZoRove if you've installed the native app).
Android doesn't ask — the sensor is available immediately.
Why it's Pro
The Leveler is a dedicated, sensor-heavy feature that lives alongside Service Records as part of the Pro Garage experience. It also requires per-vehicle setup that we hold the data for. Specs and VIN decode stay free; the Leveler and service history come together with Pro.
Troubleshooting
"No tilt sensor detected" — you're probably in a desktop browser. The Leveler needs a real device with motion sensors. Open the page on your phone or tablet instead.
Readings flicker even when smoothing is on — your phone isn't rigidly attached to the chassis. Stick it to the dash with a phone mount or sit it on a non-slip mat rather than a soft surface like a cushion.
The "level" beep keeps triggering by accident — your tolerance band is half a unit. If you're parked on a soft surface that flexes under load, micro-adjustments can push you in and out of the band repeatedly. Tap Lock once you're close.
Numbers look wildly wrong — double-check your wheelbase and track width in Edit. Swapping them is the most common mistake (wheelbase is the long one, track width is the short one).
