RTK Surveyor

I’d like to use RTK Surveyor as a guide for building a fence around my property. The corner boundaries all have professional stakes but there is no line of sight between corners. Is there and app for Android or Windows that would make it possible to do this -

1 - map the professional boundary stakes

2 - draw lines between each stake so there is a boundary around the property

3 - in real-time (or close to it) while I’m out with the RTK Surveyor, tell me if I’m to the left, right, or on the property boundary?

An app that did that would be great for placing fence posts.

If you find an app that does this, please post the name. Thanks!
