Roadie

Every navigation app assumes you want the fastest way there. Roadie assumes you would rather take the good road, and that you are probably not driving alone.

Start a drive, share a five-digit PIN, and everyone who joins gets the same multi-stop route and a live map showing where the rest of the group actually is. No account, no friend list, no social graph — the PIN expires when the drive is over.

It will also build you a loop. Tell it how long you want to be out and it generates a round trip weighted toward curves and elevation, using an OpenStreetMap graph I host and process myself rather than a routing API that thinks corners are a delay.
