Mind the Kerb — Bridge of Allan map

Zoom in, tap the map where the kerb is, pick the type, confirm. Your report goes to a moderator for checking.

Lowered: the kerb dips for crossing. Flush: level with the road. Raised: full height where you'd expect a crossing. No kerb: there's no kerb at all.

Pick the closest. Moderators compare reports from different people, so an honest guess still helps.

A crossing usually has a dropped kerb on each side. Recording both sides in one go keeps the data complete.

Privacy. Photos can capture people and homes, so the project deliberately collects none.

No — anonymous contributions count. An account adds points, streaks, and missions, and keeps your progress across devices.

A moderator checks them. Verified reports are prepared for OpenStreetMap as open data (ODbL).
