RV Leveler — Camper Level

You pull into a site, and the floor feels off. How much do you actually need to block up, and under which wheel?

RV Leveler answers that. Lay your phone flat inside the rig and it reads the tilt in both directions, then converts it into the number that matters: how many inches each wheel has to come up.

WHAT YOU GET

• Per-wheel numbers. Front left, front right, rear left, rear right. The wheel that is already highest reads as the baseline, and the rest show how far they need to rise. No mental arithmetic between an angle and a stack of leveling blocks.

• Side and front-to-rear summary. If you level the side with blocks and the ends with jacks, those two figures are right there as well.

• The 3° fridge line. Absorption (3-way) refrigerators rely on gravity to circulate coolant, and manufacturers generally advise against running them tilted much beyond about 3°. The app draws that boundary and turns red past it, so "is this good enough" has an answer instead of a guess.

• Vehicle presets. Teardrop, travel trailer, fifth wheel, Class B, Class C, Class A. Pick the closest one, or type in your own track width and wheelbase for exact numbers.

• Inches or centimeters, switched with one tap.

• Keep-screen-on toggle, for when you are outside turning a jack and the phone is on the counter.

• A short buzz when you reach level, so you can feel it without looking at the screen.

HOW TO USE IT

1. Lay the phone flat inside, with its top edge pointing the way you drive. The direction matters. Turn it sideways and left and right will swap.

2. On level ground, tap Calibrate once. The back of a phone is not truly flat because of the camera bump, and calibrating cancels that offset out. Skip this and every reading will be off by a degree or two.

3. Read the wheel numbers, stack your blocks, and watch the bubble move to the middle.

WORKS OFFLINE

No account, no sign-up, no internet needed. Campgrounds are not known for their signal. Nothing you enter leaves your phone.

ABOUT ACCURACY

Readings come from your phone's accelerometer. They are meant as a practical guide for setting up camp, not as a certified measurement. Calibration matters, and a phone resting on a soft or uneven surface will read that surface, not your rig. Confirm with your vehicle's own indicators before relying on the numbers.

Camper leveling for travel trailers, fifth wheels, camper vans, motorhomes, and just about any four-wheeled rig you park for the night.
