What's New in Apex Lines

1.7.1

October 2, 2026

Cleaner track maps: road edges on every measured circuit are now smooth, without the stair-step jumps that came from aerial width measurements. The reference lines were re-computed on the cleaner geometry, so the 2D map, 3D view and Fly mode all line up.

Wrong data for race track

I got this app for an upcoming track day, but the data about the lines and the turns is completely off.

Is so off that is showing the wrong layout for my race track (Sonoma raceway) motoGP used to run here and is a very famous and popular racetrack, is unforgivable that the layout is wrong, and on top of that the lines are very off as well. I run A group and have rode this track hundreds of times, the algorithm that they use just doesn’t know better.

Please don’t use this app to learn the lines, just ask a coach to show you the lines and you will be so much safer and faster. This is a waste of time.

Response from developer

Hi Maya, thank you for taking the time to write this. It really helps! We've reworked every track in the app, Sonoma included, and version 1.7.0 has the update. Each track also has a "Report a layout problem" button now, so you can tell us right away if something looks wrong. We agree about coaches, too. The line in the app is only meant as a reference to check your own notes and laps against. It doesn't replace a coach or all the time you've spent on track. If you try the update and something still doesn't look right, please let us know. We'd really like to hear from you. Have a great track day! — Natalia Apex Lines Team
