How detection works

1. Your phone feels the road

Your phone's motion sensors feel a sharp up-and-down jolt when you hit a pothole or speed breaker.

• Calibration: keep the phone mounted and still for a few seconds when you start. After that, its angle doesn't matter.
• Pothole or speed breaker: one strong jolt.
• Bad road: several hits within about 20 m.
• Detection pauses when you are stopped or the phone is picked up.

2. Car, Bike and sensitivity

• Car and Bike each keep their own sensitivity settings.
• Higher sensitivity means smaller jolts count. If you get false detections, turn it down.
• Sensitivity changes only what your phone detects, not the warnings you hear.

3. What gets shared

• Stays on your phone: raw sensor readings.
• Sent to our server: the hazard type, location, time and direction, linked to your account.
• Seen by others: the hazard on the map, not who reported it.

Temporary reports such as police, accidents and flooding expire after 12 hours. Other hazards stay until removed.

4. When you get a warning

About 10 seconds ahead at your speed, but never closer than 100 m. Speed cameras: about 15 seconds ahead, at least 200 m.

You only get warnings for hazards ahead of you, on your road and in your direction. You won't get warnings while standing still. You get one warning per hazard. If it isn't there, tap Not there?

5. Limits

• Phone GPS is often 5 to 15 m off, so a hazard may be marked a little early or late.
• Some jolts aren't hazards, and some hazards are missed.
• Many roads have no reports yet. Most hazards today are around Gurugram.
• Repaired roads may still show old hazards.

Warnings are a help, not a guarantee. Watch the road.
