Built for the drive

Your phone already feels every bump.

Sucky Roads uses those movements to understand the pavement beneath the car—then combines many drives so a single strange reading never defines a road.

A bump happens in a fraction of a second.

The app timestamps the motion, matches it to GPS, and evaluates it on the phone.

The signal

Designed for phones that never sit the same way twice.

Find vertical movement

Accelerometer and gyroscope readings let the app determine which direction is up, whether the phone is mounted, sideways, or resting in a console.

Place the event

GPS time, speed, direction, and accuracy locate the reading and match it to the correct road segment.

Judge the whole road

The app separates one sharp impact from longer stretches of consistently rough pavement.

Build confidence

Repeated detections from different trips and vehicles turn a possible problem into a confirmed one.

Kept on the phone

Measure constantly. Upload carefully.

  • Raw high-frequency motion is processed on the device.
  • Only useful road-condition events need to be uploaded.
  • Data waits safely if the phone loses service.
  • Personal trip history is not needed for the public map.
The goal is not to label a road from one driver. It is to build dependable evidence from many ordinary drives.
