I looked up my current residence and my childhood house.
My current residence is more or less correct given the terrain and watershed (technically it’s broken since my neighborhood is 99% impervious, meaning runoff takes a circuitous route through the sewers instead).
But for my childhood home it’s way off. I’ve hiked all the various gulleys, runs and rivers near there. The route this app gives is just not possible with the assumption that water only flows downhill.
