I have an iPhone SE 2022. I can't read the app in the iPhone. It's too large. I can only get to the screen where I can select which way the logo is facing, but I can't scroll up or down or shrink the screen to get to the save or next button. I was forced to use my iPad to set this up and level the trailer. Once it was set up through the iPad, then I could connect to it through the iPhone once I switch the Bluetooth connections. Also, a great addition would be to make this app work with Carplay so I can see on my truck dashboard instead of my phone.

I know a lot of people dislike this app for various feature or design issues. I really like it for simplicity. I use it in our Arctic Fox camper. My Ford dually has built in pitch and roll but it is not calibrated to the bed with a load. We do a lot of boondocking, and I use that to find approximately level ground. I load the app which always connects immediately for two years now, and we’ve never changed a battery. After just a few seconds, I’m leveling the camper to my perfect zero. I used a 6’ level in our cab-over with the mattress pulled out, zero’d in every direction, mounted the Beech Lane unit on the wall in one of the forward closets, zero’d per instructions, and it’s been perfect ever since. I see people complaining about inches vs degrees, but it’s real-time, so zero is zero no matter how you measure the journey. If Pepe don’t want Zero, then set the units Zero where you want the it. Overall a great, free app and device. My only gripe is having to change screens between NS/EW leveling. It looks as though they added the option now for both, so up to 5 stars from 4. BTW, every Beech Lane product I’ve purchased has been top notch. Thank you.

Believe it or not, this unit does not tell you how level you are in terms of angular degrees!! This makes it very difficult to use. You have to use trigonometry to figure out what angle you’re at!!!! The RV refrigerator says it has to be within 3°. I never know if I’m anywhere near that. I still gave it two stars because it does give you some information, even if it hides the most important stuff from the user. There’s no good reason for this oversight in my opinion. One last problem, now that I’ve used it more times I realize there’s no security. Therefore all someone has to do is download the app and they can mess up all your settings, as often as they wish.

Should really integrate with Apple Watch.
