Chock: RV & Trailer Leveler

Chock is a fast, no-fuss RV leveling app for travel trailers, campers, and motorhomes. Point your phone at level, place it in your rig, and Chock reads your device sensors to show real-time pitch and roll — then tells you exactly how many blocks or chocks to put under each wheel to get level.

No more guesswork with a bubble level. No more driving forward and back. Chock does the math for your specific rig.

WHY RVERS USE CHOCK
━━━━━━━━━━━━━━━━━━━━━

• Level in one pass — see how much to raise each wheel before you lift a single block
• Per-rig profiles — save your travel trailer or motorhome dimensions once, reuse every trip
• Tongue jack guidance — get front-to-back leveling for towable trailers, not just side-to-side
• Works offline — no signal needed at the campsite
• Inches, centimeters, or millimeters — your choice
• Leveling chime — an optional sound tells you the moment you're level, so you can watch the blocks, not the screen
• Simple calibration — correct for a phone or dashboard that isn't perfectly flat

HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━━

1. Add your rig — pick travel trailer or motorhome and enter its dimensions
2. Park roughly where you want to camp
3. Open Chock and read the pitch and roll
4. Chock tells you how many blocks go under which wheel, and how far to adjust the tongue jack
5. Level, hear the chime, and you're set up

A level rig means your fridge runs right, your doors don't swing, and you sleep flat. Chock turns your phone into a precise RV level and leveling calculator — the tool you wish came with the camper.

Whether you tow a travel trailer or drive a motorhome, Chock helps you set up level in minutes — a simple, reliable RV leveling tool for every campsite.
