Field testing traditional bubble levels against the iPhone sensor for RV leveling precision.
How It Works
Scope: This guide covers bubble level vs. iphone gyroscope: real accuracy test.
Rule: Use the three-axis gyroscope sensor data (refer to iphoneSensors.gyroscope.type).
| Specification | Value | Notes |
|---|---|---|
| Type of gyroscope sensor available in iPhone models | three-axis | Type of gyroscope sensor available in iPhone models (iphoneSensors.gyroscope.type) |
Examples
| Scenario | Angle Measured | Block Height Required |
|---|---|---|
| Front-to-back slope: 2° pitch | 2.0° | Front: 0.5", Rear: 1.5" |
| Side-to-side slope: 1.5° roll | 1.5° | Left: 0.75", Right: 1.25" |
| Combined slope: 1° pitch + 1° roll | 1.0° / 1.0° | Varies by wheel position |
FAQ
How accurate is the iPhone sensor for RV leveling?
The iPhone's built-in gyroscope and accelerometer provide accuracy within 0.1° when properly calibrated. This is sufficient for RV leveling, as most RVs are considered level within 1-2° of horizontal.Do I need to calibrate my iPhone before each use?
Yes, calibration is recommended, especially if you're using a phone case or if the camera bump affects the sensor reading. The app's zero-point calibration feature accounts for these offsets.Can I use this app for any RV type?
Yes, RV Leveler supports both motorhomes (4-point leveling model) and trailers (3-point leveling model). The app adapts its calculations based on your vehicle type selection.Download
