What is this tree in DC/MD/VA ?

HI all,
This tree is very distinctive, very easy to spot from the leaves and the particular bark, I see it everywhere around the DC/VA/MD area. I tried several tree finder apps but none gives me an identification. It bothers me not to be able to find its name.

This tree is everywhere so it may be an easy question, my apologies for it,  but would anybody be able to tell what is this tree name?

It looks like it might be a wild cherry.

The name Wild Cherry Tree refers to a number of species in the genus Prunus.  Some of the more common are the Black Cherry (Prunus serotina) and the Chokecherry (Prunus Virginiana) both native to North America.  There is also a species native to Europe called wild cherry ( Prunus avium).   All these species have similar characteristics.
