It is given to you on Route 207 by "Rowan's Assistant" (Dawn or Lucas). It's a required item (I don't think you can avoid getting it.)


Once you obtain the bicycle and head down the bicycle road, on the other side you'll automatically talk to Assistant. I don't think it matters which hand you choose. You'll receive the Dowsing App and the VS Seeker.

EDIT: This is half based upon online guides, half based upon memories from playing.
