I am looking for an app that can take two points marked on a map and then triangulate a third point with a given distance from those two initial points.
So if I mark A and B on the map and give a 200m distance, it would show me the two points that are ~200m of distance from both A and B (+ - GPS precision).
Requirements for the app:
It can be online or offline. Offline preferred but not mandatory.
Android preferred but I won't tag it as Android since if there is a great alternative for iOS that can be useful to others.
Free or below USD 5.00
I will physically visit points A and B but if an app can have these points marked on a map and then calculate, that is fine too.
