I just did a test on my trailer with Level My RV. The measurements for my trailer are 205" from front axle to tongue and 80" from inside tire to inside tire width. My trailer is parked on level concrete wheel tracks. I used Level My RV, Levelmate Pro and the "Measure" app. My Levelmate shows it level side to side and front to back. The "Measure" app shows it off by 1 degree side to side with the right side lower and it shows level front to back. Level My RV shows it off by .2" side to side with the right side lower and .5" off front to back. The accuracy is very close...close enough for RV spots! This is a great addition to making the whole setup process easy. I used an iPhone and an iPad using both as the measuring device and the remote device. The remote connection is quick and clear. Good Job!

Just tried using iPad as the sensor and iPhone as the viewer in my 22’ travel trailer. This wonderful application is going to take a lot of frustration out of the leveling process especially if setting up the camper without a helper or in the dark! This is also going to save wear and tear on my tow vehicle (and me) by not repeatedly pulling forward, adding a block, reversing, etc while blindly guessing how much side-to-side leveling is required. There is good Bluetooth communication between iPad and phone well beyond front of tow vehicle. I also love the simplicity and crisp clean layout of the app. THANK YOU!

used it today and it’s so accurate our shower door will stay open at any point now - REALLY nicely done - I’m using an iPad as the sensor in the bathroom for the larger surface area and an iPhone as display at the steering wheel where the leveling controls are. Layout is very user friendly and easy to setup. Excellent app all around.

This app is truly worth the price. I would gladly pay for it! Used for the first time in a crocked uneven site. The integration with my watch made this a one and done operation. Five stars isn’t even enough!!
