It's also $350+, needs mounting, needs charging, and needs pairing every time. OzLevel uses the precision sensors already in your phone. Here's an honest look at what you actually get for the difference. --- ## The honest version upfront This article is written by OzLevel. We have an obvious interest in you choosing OzLevel over SavvyLevel. We're telling you that upfront because the comparison below is still accurate — and we'd rather you trust it than wonder. SavvyLevel is a capable, well-reviewed product. If you've already bought one and love it, keep using it. But if you're deciding between the two, or wondering whether a dedicated sensor is worth the cost, the answer for most Australian motorhomers is no — and we'll explain exactly why. ## What each product does OzLevel Best value $9.99 AUD · one-time · Pro upgrade - ✓ Uses sensors already in your phone - ✓ Millimetre rise per wheel - ✓ Exact ramp step count (Pro) - ✓ Dual-axis simultaneous - ✓ Hands-free audio mode - ✓ Slideout seal protection - ✓ 100% offline - ✓ No mounting or pairing - ✓ iPhone and Android - ✓ No App Store required - ✓ Australian-made and supported SavvyLevel Dedicated sensor $350+ AUD · hardware purchase - ✓ Dedicated Bluetooth sensor - ✓ Dual-axis simultaneous levelling - ✓ Exact ramp step counts (Top View) - ✓ Permanently mounted — always ready - ✗ Requires mounting (permanent) - ✗ Requires charging - ✗ Requires Bluetooth pairing - ✗ No hands-free audio guidance - ✗ No slideout seal protection mode - ✗ App Store download required - ✗ Additional hardware to maintain ## The accuracy argument The main case made for dedicated Bluetooth sensors like SavvyLevel is accuracy. The claim is that a purpose-built sensor is more accurate than a phone. In most contexts, that's a reasonable assumption. For levelling a parked motorhome, it doesn't hold up. Here's why. Sensor drift — the phenomenon that makes phone sensors less reliable than dedicated hardware — occurs in **dynamic applications**. Navigation. Motion tracking. Augmented reality. Applications where the sensor is reading a moving, changing environment and small errors accumulate over time. Levelling a motorhome is a **static application**. You park. You stop. You take a reading. The phone reads gravity. Gravity doesn't drift. There is nothing to accumulate error against. Temperature compensation matters for continuous motion tracking over hours. For a single static reading taken on-site, which is how motorhomers use a levelling tool, thermal effects are negligible. Even if a phone sensor drifted with temperature changes, a 1–2° variance is still within the operating tolerance of your fridge. Remember we are not levelling a pool table. > ✅ **The numbers — from the manufacturers themselves:** Dometic specifies a maximum of 3° side-to-side and 6° front-to-back for their absorption fridges. Thetford states the same. A modern smartphone on a static vehicle achieves better than 0.5° — four to six times more precise than the tolerance you're actually working within. The accuracy argument is compelling for a boat on water, a vehicle in motion, or a sensor doing continuous monitoring. For a motorhome you've just parked on a campsite, it's a solution looking for a problem. ## The real cost of dedicated hardware The sticker price of SavvyLevel is $350+. But that's not the full cost of ownership for a dedicated hardware sensor on a motorhome. Cost item OzLevel Pro SavvyLevel Purchase price $9.99 AUD $350+ AUD Mounting hardware None Time + materials Ongoing charging None — uses phone battery Separate battery to manage Pairing friction None Bluetooth pairing each trip Replacement if lost/damaged Already on your phone $350+ again Works on any phone Yes Depends on Bluetooth compatibility Effective total $9.99 $350+ plus ongoing friction The time cost matters too. Before every trip, SavvyLevel needs to be charged. On site, it needs to pair with your phone over Bluetooth — which works smoothly until it doesn't, and "Bluetooth not connecting" is a real and frustrating failure mode in a remote campsite. OzLevel opens in your browser in three seconds. No pairing, no charging, no failure modes. > **Try it before you spend $350.** Open OzLevel free at [app.ozlevel.com.au](https://app.ozlevel.com.au) on your next trip. If it does everything you need — and for most motorhomers it will — you've saved yourself $340 for a tank of diesel. ## Common myths about phone sensors The case for dedicated hardware often rests on assumptions about phone sensors that don't hold up for this specific use case. Here are the ones you'll hear most often. ### "Phone sensors drift" True — in dynamic applications. Sensor drift is a real phenomenon in navigation, motion tracking, and augmented reality, where a moving sensor accumulates small errors over time. It is not relevant to a parked motorhome. OzLevel takes a static reading of a stationary vehicle. The phone reads gravity. Gravity doesn't drift. ### "Phones need to be perfectly flat to get a good reading" OzLevel needs to be placed on a flat, stable surface inside the vehicle — the kitchen bench or dinette table works well. It doesn't need to be independently level; it measures the lean of the vehicle itself. A slightly warped benchtop or a phone case with a raised edge can affect accuracy, which is why OzLevel recommends removing cases for best results. ### "A dedicated sensor is always more accurate" More accurate for what? A dedicated sensor mounted permanently to a vehicle chassis may be marginally more precise in a controlled comparison. But the relevant question is whether that extra precision matters for levelling a motorhome, where the tolerance is 2.5–3°. At sub-0.5° phone accuracy, you're already operating at a margin that makes no practical difference to your fridge or your sleep. ### "Bluetooth sensors work in any conditions" Bluetooth is reliable most of the time. It's also the component most likely to fail — dead battery, interference, pairing dropout — in exactly the kind of remote location where you most need your levelling tool to work. OzLevel has no wireless dependency between sensor and display. It's one device, reading its own sensors, with no connection to maintain. ## Where SavvyLevel genuinely wins It's a fair comparison, so here's where the dedicated sensor has a real advantage. ### Permanently mounted SavvyLevel mounts to your motorhome and stays there. You don't need to remember to place your phone on a flat surface inside the vehicle and wait for a reading. The sensor is always in the right position — you just open the app. If you want a setup that requires zero physical preparation at each site, a permanently mounted sensor does that. ### Real-time continuous display SavvyLevel provides a continuous real-time display as you drive onto ramps. OzLevel's reading updates in real time too, but your phone needs to be somewhere you can see it — or you use audio mode. For some people, a dedicated display is genuinely more convenient. > 💡 **The honest summary of where SavvyLevel wins:** the sensor is always correctly positioned — no placing your phone on the bench before each reading. That's the real convenience advantage. Not accuracy, not phone independence — SavvyLevel still needs your phone to display anything. ## Feature comparison | Feature | OzLevel Pro | SavvyLevel | | --- | --- | --- | | Price | $9.99 AUD once | $350+ AUD | | Ramp step calculator | ✓ | ✓ | | Dual-axis simultaneous levelling | ✓ | ✓ | | Millimetre rise per wheel | ✓ | ✓ | | Accuracy (static vehicle) | <0.5° (per manufacturer) | ±0.1° (per SavvyLevel) | | 100% offline | ✓ | ✓ | | Hands-free audio guidance | ✓ | ✗ | | Slideout seal protection | ✓ | ✗ | | Permanently mounted | ✗ | ✓ | | Requires charging | No | Yes | | Requires Bluetooth pairing | No | Yes | | Requires phone to display | Yes | Yes — Bluetooth app required | | No App Store required | ✓ | ✗ | | iPhone and Android | ✓ | Check compatibility | | Australian-made | ✓ | ✗ | ## Who should choose what ### Choose OzLevel if… - You want the ramp step count calculated for you automatically - You level solo and want hands-free audio guidance - You don't want another piece of hardware to mount, charge, and pair - You travel to remote areas where Bluetooth failure is a genuine annoyance - Your motorhome has a slideout and you want seal protection built in - You're pragmatic about cost and what you're actually buying ### Choose SavvyLevel if… - You want a permanently mounted sensor that's always in the correct position - You prefer dedicated hardware and the peace of mind that brings - You don't mind managing another battery and Bluetooth pairing device - Cost is not a primary consideration > **Try before you decide.** Open OzLevel free at [app.ozlevel.com.au](https://app.ozlevel.com.au) and use it on your next trip. If it does everything you need — and for most people it will — you've saved yourself $340. If you still want the dedicated sensor after trying it, you'll at least know what you're paying for. ## The verdict For the vast majority of Australian motorhomers, OzLevel Pro at $9.99 once does everything SavvyLevel does — and adds features SavvyLevel doesn't have, including hands-free audio and slideout seal protection. Both calculate exact ramp step counts and level both axes simultaneously. The accuracy is comparable for the only use case that matters: a parked motorhome. SavvyLevel is a good product with a real use case — permanently mounted, always available, no phone required. If that's what you need, it's worth the money. But if you're deciding based on levelling performance, OzLevel wins on features, wins on price, and wins on the only metric that matters in a remote campsite: it works every time with zero friction. --- *OzLevel is a free Australian Progressive Web App for levelling motorhomes and caravans using your phone's built-in sensors.
