A crash: going past a rumble strip on either side of the road. The Roll Cage part forgives one crash per gate.

Force-quit Hairpin and open it again, then restart your iPhone. Hairpin needs iOS 18 or later: Settings → General → About shows your version, and Settings → General → Software Update installs updates.

If it still will not open, delete Hairpin and install it again. Reinstalling deletes your local progress, because progress, records and the saved run are stored only on your iPhone. If none of this helps, email support@x3r0soft.com.

Progress, records, unlocks and the saved run are stored on your iPhone only. x3r0soft never receives them, so they cannot be recovered by x3r0soft. Deleting the app or using Settings → Reset progress removes them. If progress disappeared without either, email us with your iPhone model, iOS version and game version.

Open Settings in Hairpin. Sound follows the iPhone silent switch and mixes with music from other apps. Sound and haptics can be switched off in Settings.

Yes. Hairpin follows the iPhone setting: Settings → Accessibility → Motion → Reduce Motion. Every control works with one finger.

Email support@x3r0soft.com with the subject “Hairpin support”. Include your iPhone model, iOS version, the game version from Settings → About & support, what happened and when, and a screenshot if it helps. The Email support link in Settings → About & support fills in the subject and the versions for you.
