Is there a convenient tool for building a user flow map?

Question

Design

There is a fairly large number of application screens in png. It is necessary to collect one large png from this with screen connections (from where to where and after that). What can be used for maximum productivity and convenience under mac?
It was tried:
Sketch - generally ok, but the default arrows are very small (the head of the arrow itself), respectively, on a large image, they are very inexpressive. I don’t know how to work with custom arrows (when I try to stretch the sketch, it enlarges all elements proportionally, so we have giant arrowheads). First experience, so any advice would be welcome.
Preview - roughly the same problem as in Sketch
Options in the head:
Photoshop/Illustrator - looks like a hard overkill and time consuming
UPD. I have now found a solution for myself. If someone knows an even better tool, then please answer :)

Answer 1

Today there was an update for Sketch (39) .
Now you can set up resizing rules for group elements. Accordingly, custom arrows solve all problems.
Adobe XD: Looks promising, but doesn't yet know how to draw arrows from dots on the image. Accordingly, it is convenient if the whole design is in it, but as a tool for compiling a flow from images, it is inconvenient. In addition, I did not find a way to always display arrows, only when a specific image is selected. By the way, it has not yet been released for free.

In illustrator, I do it there: joxi.ru/82Qepngtq90E2d
Through the pen, you can create a line, set the arrow parameter to it (ctrl + F10). Well, then copy it and drag it anywhere

Well suited for presentation, customers really like it.

Mind mapping will do it best
