2 questions Osmand

I am a fairly new user of Osmand and would like to know if it is possible to turn a track or route in Osmand instead of having to do that in Basecamp and then export the track or route to Osmand. Ansd also I would like to know if there is something like a slope angle meterapp for bikes that works in or with Osmand.

Hope someone will be able top help me out.

You can use Osmand to plan your route or you can import the route from an external file.
Try Brouter for planning bicycle routes considering terrain. Brouter is integrated in Osmand.
