To be honest

I’ve been around since the early days and I really like this app.

Not accurate

Feels like the readings are just a random number generator. You can go as fast as possible or as slow and anywhere in between and get a different reading every time.

Not what it was

This was close enough back when it first came out, now it’s wildly inaccurate and completely useless. Sad

Great system. Could be better

Pretty big miss you have to watch the screen instead of the contact surface to know that you're lined up ... and the resolution in settings never stays at your last selection. Will change to 5 stars when you add the audible!

Excellent Tool

I’ve used Gyraline to align 3 cars now, with excellent results each time. The process isn’t the most intuitive, but their instructional videos explain it well. Once you get the hang of it, it’s easy to get repeatable measurements, but it does take some effort to learn.

This is miles better than using string and calipers. The amount of time you save each time you check a measurement is worth the price alone. Highly recommend if you do any of your own work on your suspension or just want to align your car perfectly.
