Lay your phone flat and see how high to build up under each wheel.
• Live level: bubble and tilt in degrees, readable in portrait and landscape and from a few steps away.
• Block height for all four wheels at once, with the wheel to raise first highlighted and the number of stacked blocks of the thickness you choose.
• Your vehicle: wheelbase and track width (front and rear), in metres or inches.
• Zero button to correct for the way the phone sits, saved per vehicle.
• Payload and axle load check against the values in your vehicle papers, shareable as a PDF.
• Towing check for car and caravan: laden weight, braked towing limit, train weight and nose weight.
• Saved vehicles and saved spots, so you know what you need next time.
• Night mode in red, vibration when level and optional voice guidance.
HOW IT WORKS
RV Level uses the gravity and motion sensors built into your phone. Put the phone flat on the ground, a step or the dashboard. The block heights are an estimate calculated from your vehicle's sizes, not a certified measurement. Weights and towing figures are guidance only: always check your vehicle papers.
Works offline, no account. The app contains ads. An optional one-time Pro purchase removes them; every feature works without it.
