Hey Guys!
I'm Sam, the Engineer behind all of this madness. One of my friends sent me here! I'm a die hard car guy and really needed a way to do a more accurate alignment and FAST. With your iPhone (Android has a very limited [free] tech demo that only works on select devices) and our plastic phone adapter you can measure toe in about 20 seconds per axle. You'll want the phone adapter for the parallel protruding edges.
For pricing, the current model is pay-as-you-go and you can try it now for free: we are always improving accuracy and adding features. Users get the most advanced algoithm at 99 cents per one hour session, and the first three are free. More modes of pricing might be added soon, as we get more feedback around the subject.
We are ALWAYS open to suggestions on improvments to the app and pricing structure, so dont hesitate to reach out if you have anything in mind. We're based in San Antonio and you can find us on Instagram @gyraline and I am @samwontstop, a co-founder of the company.
Thank you for the interest!
Sam
