"The numbers reported by GYRALINE were exactly the same as the professional alignment I had done previously. It’s a very nice tool!"

Was a little skeptical but pulled the trigger, even bought a used iPhone just for this as i have a 1965 Shelby Cobra Daytona Coupe thats more race than street car and requires multiple alignments a year. With the help of a friend we got her in spec in less than an hour and that includes being way out of spec from replacing several suspension components beforehand.
Now that Ive done it a few times im sure I can do it in about 1/2hr solo.

After a full steering upgrade and lift kit I needed an alignment. Picked this up and had my jeep aligned my jeep in 20 minutes. This tool cost me less than what the local shop wanted for an alignment. Now I can check and adjust my alignment every time I rotate the tires and maximize my tire life.
I have a track day car I also use for autocross. I always pullout the strings and set up the alignments for my car and a few friends. I tested it my measurements on the string and this system was more accurate, and ten times earlier to setup.
Easy of use.
Works as described.
Works awesome
loved it…..ease of use….simple to get started….Used it on my 2016 JKUr that hasn’t driven straight in 4 years…..went from using all five lanes of the freeway to one handed driving in a matter of two hours of dialing in the steering geometry. We learned measurements we didn’t even know was out of alignment. Nice to see the measurements with a visual aid as well to give you a better understanding of what is going on.
WOW! easy to use worth every penny
great invention
they sent these out to me free of charge, I really appreciated the quality service and taking care of the customer. Thank you.
So far, in 3 days I have corrected issues with 2 of my vehicles…. Paid for itself already! Definitely worth the money, just take your time and stay steady! Great tool!
So far it's been great! Already found a good up from an old shop. Going to next try settingmy own alignmentup and really test how well it works
Awesome tool, its accurate, easy to use and works well. Follow the steps properly and it'll work properly.
I'm an Android guy but got a cheap iPhone just for this app and it works quite well. My first time really using it was to baseline my alignment after replacing almost every part of my car's suspension with adjustable parts. It does involve more back and forth as opposed to a traditional alignment machine, but I spent two evenings getting it done, vs $$$$ at a shop. I did drop my cradle and chipped a corner. When I asked about buying a replacement, they sent me a free one, no questions asked, so also definitely big props for customer service. Totally worth having and easy to use once you get used to it.
Little bit of a learning curve, make sure it is level when taking the reading but got me to within .05 Degrees of the mark using a $ 100.00 refurbished iPhone 12. The only reason had to Run the 2016 Patriot to Shop was to install New Right Camber Bolt and who ever torqued it last time used a 400 pound wrench.
I am looking forward to see the next generation, please get a video up as soon as possible. thanks mark Owens, Phoenix Az
