Arrow on own position marker

[PE1MIU]

I am trying to figure out what direction the arrow points to of your own position marker in the app. Probably the explanation is simple but I cant’t figure it out by myself

Hi Frank,
the arrow points to your direction, so by aligning your direction to the track that connects your position to the radiosonde position, you can reach it.

If your direction in not correctly, perhaps your smartphone does not have an electronic compass or it needs to be calibrated.
