Note: This feature has been experimentally released in version 0.8. Please, continue bidding to support further development and fine tuning!
The quality of routing is expected to be at basic level. OsmAnd will provide step-by-step voice guidance with next maneuver countdown in car, bycicle and pedestrian modes. In case of detour, the route will be recalculated.
Rationale: Phone screens are small, so sometimes it's quite difficult to head the right direction to get to your destination. A line which shows you the root helps a lot on the high zoom level.
Please note that usability in your area will be influenced by the quality of OpenStreetMap data.
