Which wheel goes on the blocks, and how high. Then a departure list that knows your rig: step, vents, power cord, hitch. Works offline, no account.
Which wheel goes on the blocks, and how high?
Lay your phone on the floor and Chocka answers for every wheel: front left 3.5 in on step 4, front right 2.25 in on step 2, rear left 1.25 in on step 1, rear right stays. It works from your own wheelbase and track and the steps of your own leveling blocks or ramps, and tells you how level the rig will sit once it’s on them. The bubble sits in the middle of your rig, so you can see which way it leans.
TRAVEL TRAILERS TOO
Two wheels and a tongue jack: which side goes up, and how far to wind the tongue jack up or down, worked out together so the second adjustment doesn’t undo the first. Single or tandem axle.
HOLD IT, THEN WALK OUTSIDE
Freeze the reading and take it to the wheel. A firm tap tells you when the rig comes level.
CALIBRATE IN 20 SECONDS
Two readings, one each way around, on any flat surface. Every phone’s tilt sensor is a little off; this cancels it out.
LEAVE NOTHING AT THE SITE
Leaving, arriving and packing lists that know what you drive. A motorhome gets the entry step, the roof vents, the TV antenna and the shore power cord. A travel trailer gets the coupler, the safety chains and breakaway cable, the trailer lights, the tongue jack and the stabilizer jacks. Safety items are flagged, and if one is still open when everything else is ticked, Chocka names it.
YOUR RIG, REMEMBERED
Your tire pressures show inside the tire item. Add, rename, reorder and flag items. New trip unticks the list and keeps your changes. Several vehicles, each with its own lists.
PAYLOAD CHECK
GVWR and weighed weight, plus people, water, propane and luggage: how much you can still load, or how far over you are.
Inches or centimeters, psi or bar. English, German, Dutch and French.
Works offline. No account. Your lists stay on your phone.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Meet Plug, a small hook-up plug: he waves on the last intro page, waits when no sites are saved and cheers when you tick the last Leaving item.
• A reading between two block heights now rounds up to the next block.
• The caravan arriving list levels the van before unhitching.
• A full propane bottle now defaults to 24 kg.
