🎯 Level Assist

Overview

An unlevel van is a surprising source of discomfort — sleep quality suffers, things roll off surfaces, and that slow creeping headache that arrives after cooking for an hour in a gently tilted kitchen is entirely preventable. Level Assist uses your iPhone’s built-in gyroscope and accelerometer to show you exactly how far off level you are and which direction to correct it.

When you enter your van’s wheelbase and track width, it goes one better: it calculates exactly how high to raise each wheel with ramps or blocks, in millimetres, so you can hit perfectly level on the first try.

Opening Level Assist

Tap Leveling Assistant on the Van tab home screen (below the Digital Glovebox card). The Level Assist screen opens as a full sheet.

The Bubble Instrument

The main display is a circular leveling instrument — an electronic spirit level — with a bubble that moves in response to your van’s tilt.

When level: the bubble sits in the centre circle and the entire instrument turns vivid green. Your phone vibrates with a success haptic. If audio is enabled, a tone plays.

When close: the instrument glows orange — you’re within 3× the tolerance and nearly there.

When significantly tilted: the instrument shows red. Keep adjusting.

Ghost Chassis

Behind the bubble instrument is a faint silhouette of a vehicle chassis — a visual reference for orientation. It helps you relate the bubble’s position to your van’s actual posture: bubble top-right means the van is tilted back-right (front-left elevated), and so on.

Pitch and Roll Readout

Below the instrument, two values update in real time:

Pitch (°) — Forward/backward tilt. Positive pitch means the front is higher than the rear; negative means the rear is higher.

Roll (°) — Side tilt. Positive means the right side is higher; negative means the left.

Values update several times per second as the van settles.

Precision Mode (Wheel Raise Calculations)

If you’ve entered your van’s wheelbase and track width in the Van profile (Settings → Van → Edit → Fluids & Technical), Precision Mode activates automatically. A “Precision Mode” label appears below the screen title to confirm it.

In Precision Mode, four wheel raise indicators appear as an overlay — one at each corner of the chassis ghost:

Front Left (FL)
Front Right (FR)
Rear Left (RL)
Rear Right (RR)

Each shows how many millimetres to raise that corner to achieve level. If the value is positive, raise that wheel. If it’s zero or shows a dash, that wheel is already at or below the reference plane and doesn’t need raising.

Place ramps, chocks, or blocks to the calculated height at the indicated corners, drive forward or backward onto them, and check again. With practice — and good ramps with marked heights — you can achieve level in one or two adjustments.

Calibration

To calibrate:

Park the van in a position you’ve manually confirmed is close to level using a physical spirit level or bubble app as reference.
In Level Assist, tap Calibrate (bottom of the screen). The current orientation is saved as the zero reference.

Calibration offsets are useful if your phone mount introduces a tilt, or if you want to calibrate to a “close enough” baseline rather than true level.

Tap Reset Calibration to return to the phone’s raw sensor readings.

Accuracy Settings

Tap the gear icon (top left) to open the Accuracy Settings sheet. A single slider controls the tolerance — how much tilt is accepted before the instrument shows green.

Lower tolerance (leftward): stricter — the bubble must be very close to centre
Higher tolerance (rightward): looser — a gentle tilt is considered acceptable

Default tolerance is 0.5°, which is a reasonable standard for sleeping and cooking. If you have a spirit-level reference installed in the van and have verified that 1° is comfortable enough for your needs, raise the tolerance accordingly.

Audio Feedback

Toggle audio on using the speaker icon (bottom of the screen). When audio is on:

A tone plays when level is achieved
The tone is brief and non-intrusive

This is useful when you’re outside the van adjusting ramps and can’t see the screen clearly.

Tips for Best Results

Place your phone flat on the van floor or a horizontal countertop for the most accurate reading. A suction mount on the windscreen introduces slight variation due to vibration.
Give the van time to settle after each ramp adjustment — the suspension needs a moment to find its rest position before the reading stabilises.
Use four separate pieces of ramp/board rather than two long boards along each side, for finer independent adjustment at each corner.
The gyroscope is accurate but not a surveying instrument. A ±0.2° variation at rest is normal.
