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. ### 5/5 — Works great when used as directed *2026-06-01* Don’t assume you know how to use this tool just because you may have used others. I did that and found inconsistent results and thought the problem was the app or the tool itself. Later I took 15 minutes and watched the instruction videos which explain exactly how to use the G1 tool and saw that I was doing it wrong, which explains why I was getting inconsistent results. I also want to say that I’ve had extremely good experience with their support team regarding my order and the product. Lastly, I found that my Office 365 email mistakenly flagged their product activation link as spam and I had to release it from quarantine before receiving. This was a Microsoft issue, not a Gyraline issue. ### 1/5 — Word to the wise: Stay Away. *2026-05-18* It is a giant POS! It locked to the email you used to purchase which happened to be my work email. I can’t use the app on my work phone. They said they had changed it to my personal email, and now I can’t use either. They never mentioned that when ordering. Even if they fix it, the need to always send a validation link is incredibly annoying. I plan to dispute the charge of my CC as they have failed to provide the function that was advertised as I have never been able to use it. ### 1/5 — Can’t open/ No support *2026-05-09* I was really excited to get this. I paid the $189 for lifetime subscription. The app will not send a link so I can use the app and I have written customer service several times over the last few days. I tried changing my email in my account in case fraud filters were blocking but absolutely no luck. No number to call and zero response which says typically responds same day. I will be filing for a refund on my credit card! Pretty bummed! ### 5/5 — Great tool love it. *2026-05-01* Most of my issues when not clearly knowing the process of how to use the tool correctly. I’m am a master mechanic but alignments have never been my wheelhouse. After a few try’s and watching multiple videos I got my alignment perfect. Just needed to take my time and follow each step correctly. From now on I’ll definitely do my own alignment. ### 5/5 — I’m sold *2026-04-30* There’s a bit of a learning curve as with any new tech. And it takes patience to get repeatability until you’re used to the process but I’ve completed 3 successful alignments so far. It’s already more than paid for itself. The manual could use an update but if you understand what you’re doing in the first place, it’s not an issue. Update: brought one car in for new tires after aligning it with Gyraline. A free alignment check came with the purchase and after the adjustments I made prior with the app, their machine indicated I was off by only .05 degrees on the left front tire. I’ll take it. ### 5/5 — Awesome & Quick alignment app! *2026-04-30, version 3.1.671* So much better than measuring tapes! It’s nice to finally have a way to do decent alignments at home! ### 1/5 — Extremely frustration *2026-04-05, version 3.0.634* Extremely frustrating. Things are not accurate. You can measure the car back to back and the numbers are completely different and not even close together. You can’t measure, do a small adjustment and measure it again. It makes you go though the entire car again just for that short adjustment. This is not practical at all. String and tape measure is much much better than this wonky thing. It’s a shame. ### 5/5 — I’m sold *2026-03-16* There’s a bit of a learning curve as with any new tech. And it takes patience to get repeatability until you’re used to the process but I’ve completed 3 successful alignments so far. It’s already more than paid for itself. The manual could use an update but if you understand what you’re doing in the first place, it’s not an issue. ### 5/5 — I like the new update *2026-03-10, version 3.0.634* Body align is always spot on, spec lookup is super cool, as well as the garage feature, now I can save alignments from before when I was at the track and track how everything feels. ## Frequently asked questions about Gyraline ### What does Gyraline do?
