About this app

CoDriver calls the road ahead like a rally co-driver. Pick a road, press START, and a voice reads a pacenote for every corner, “150 long left 4 minus, tightens 3”, timed to where you are. The notes are built from map data: no recce, nothing to drive or record first.

Made for the Sunday drive over a mountain pass, the back road home and the road trip you have been planning.

FOUR WAYS TO DRIVE
• Follow the road: one tap. CoDriver takes the road you are on and calls it ahead, through junctions. Turn off and it follows the new road.
• Where to?: search for a place or drop a pin. CoDriver routes there and calls the route, and reroutes if you take another turn.
• Plan a route on the map: start, stops and end. The notes are built before you go and stored, so the drive works without signal.
• Famous stages and roads: Ouninpohja, the Col de Turini, the Stelvio and more are waiting in My routes. Watch real onboard footage with the notes called over it, or simulate the drive from your sofa.

THE NOTES
• Corners graded 1 to 6, with half grades (+ / −) if you want them
• Hairpins and square turns, long and very long, tightens and opens, “into” and “and”
• Crests where the terrain data is precise enough (lidar). Each route shows “Corners + crests” or “Corners only”, so you know what you get
• Your grade scale: 1 or 6 as the tightest corner
• Grading, from very brave to very cautious
• Crest filter, from severe crests only to every one
• A co-driver voice made for pacenotes, with an optional rally-helmet intercom sound
• English, Estonian, Finnish, French, German and Dutch, for the app and the calls

DRIVE SAFELY
The notes come from OpenStreetMap and terrain data, not from anyone driving the road. They can be wrong or out of date: roadworks, new junctions, gravel, a badly mapped corner. Drive to what you see, and always obey traffic laws: speed limits, your lane and other road users come first. CoDriver never tells you how fast to drive. Mount your phone and set your route before you set off.
