Safety and accuracy

  • Set up the mount and the app before you drive, and don't operate CapDrive while driving. Let a passenger do it, or park safely first.
  • Always obey traffic laws and speed limits. Only try hard acceleration, launches, timing runs or drifting where it's legal and safe, such as on a closed track.
  • CapDrive's readings are estimates from the iPhone's sensors and GPS. They can be inaccurate or unavailable, and CapDrive isn't a certified measuring instrument. Don't rely on it for safety, legal, insurance or vehicle maintenance decisions. See the Terms of Use.
