The new levelling app
for Motorhomers

Nope. OzLevel is a Progressive Web App (PWA) — you access it through your browser and add it to your home screen just like a normal app. No App Store, no Google Play, no waiting for approval.

Watch the setup walkthrough below — it covers how to enter your block height, vehicle details and how to calibrate your phone so OzLevel can give you accurate readings.

Most levelling tools aim for perfectly flat — but perfectly flat isn't always ideal. If your motorhome has a slideout, water pooling against those rubber seals over time causes premature wear and leaks. OzLevel's Pro seal protection mode biases the slideout side just a few millimetres lower than perfectly level when possible — enough to encourage water to drain away from the seals, not enough to affect your comfort or appliances. It's a subtle feature most people don't think about until they're facing an expensive seal replacement bill.

As a one-person Australian operation built by a fellow motorhome owner, OzLevel focuses on real-world simplicity for grey nomads and outback travellers. It eliminates guesswork with about 15mm accuracy on static readings (better than most RV appliance tolerances) while keeping costs minimal and requiring zero extra gear. Pro users especially love the ramp stack calculator and slideout protection that help prevent long-term seal damage.

OzLevel requires no extra devices or sensors — it uses the accurate accelerometer and gyroscope already in your phone. Caravan Level Remote needs a second phone or watch for remote reading (iOS-focused). Dedicated hardware options (SavvyLevel, Possum, Oricom) cost $100–$350+, require mounting, charging, and Bluetooth pairing, and can have battery or connection issues in remote areas. OzLevel is far cheaper (free tier or $9.99 one-time Pro), has no ongoing maintenance, and includes unique features like the exact ramp block calculator and slideout seal protection tailored for Australian motorhomes.

OzLevel gives you precise millimetre rise required at each wheel and (in Pro) the exact number of ramp blocks to stack — plus dual-axis levelling at the same time and a dedicated slideout seal protection mode. Many other simple apps only show basic degrees, colours, or beeps without the practical "how many blocks" guidance that saves time at camp. OzLevel is also a PWA (add to home screen from browser) so no app store install is needed, and it works completely offline.

100%. OzLevel uses only your phone's built-in sensors — accelerometer and gyroscope — which work completely offline. Once you've loaded it once on wifi or data, it's fully available wherever you are.

Any brand. You enter your ramp block height in the settings and OzLevel calculates based on that. Camec, Tufway, generic blocks and even Milenco 4 tier blocks — doesn't matter.

OzLevel works on any smartphone made in the last 8–10 years. If your phone has a browser and a built-in compass or level, you're good to go.

This is the hardware vendors' favourite talking point — and it's misleading. "Sensor drift" is a real issue in dynamic, moving applications like navigation or motion tracking. OzLevel takes a single static reading of a stationary vehicle. Your phone reads gravity. There's nothing to drift.

Most RV appliances are rated to ±2–3 degrees. OzLevel achieves accuracy well within that tolerance. We're levelling a motorhome, not calibrating a gyroscope or levelling a billiard table.

Because you already own a phone. Dedicated Bluetooth levelling sensors cost $100–$350 and more, need charging, pairing, mounting, and eventually replacing. OzLevel uses the precision sensors already in your handset — accurate to about 15mm of rise. Free tier at no cost. Pro at $9.99 once. The maths does itself.
