Do I need to download it from the App Store? +
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.
What's the slideout seal protection feature? +
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 (usually driver's 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 Pro feature that most people don't think about until they're facing an expensive seal replacement bill or water damage repairs.
Does it actually work without internet? +
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.
What ramps does it work with? +
Any brand. You enter your ramp block height in the settings and OzLevel calculates based on that. Camec, Tufway, generic blocks — doesn't matter.
Will it work on my older iPhone or Android? +
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.
Aren't phone sensors less accurate than dedicated hardware? +
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.
Your fridge's operating tolerance is ±3 degrees. Most RV appliances are rated to ±2–3 degrees. OzLevel's accuracy on any modern smartphone (2016 onward) is ±0.5 degrees. That's six times more precise than you actually need. We're levelling a motorhome, not calibrating a gyroscope or levelling a billiard table.
Why use a phone app instead of a $150+ Bluetooth sensor? +
Because you already own a phone. Dedicated Bluetooth levelling sensors cost $100–$200 an more, need charging, pairing, mounting, and eventually replacing. OzLevel uses the precision sensors already in your handset — accurate to under 9mm of rise. Free tier included at no cost. Pro at $9.99 once. The maths does itself.
What if I'm not happy with it? +
