Coverage heat-map tool?

Hi guys,
I have just swapped out a few Ubiquities for AP6-Pros and would like to do a review/comparison of the coverage.
What tool do you recommend (preferably free if that exists, or not that expensive) that I could put a drawing of my building and see before and after? Still have the Ubiquities laying around so could plug-them in again for an hour or so and walk around and do this heat-map-thingy…and then quickly back to Alta again! :wink:


A few users have recommended Acrylic:

Or Netspot:

But there are quite a few out there :slight_smile:

Let us know how the comparison goes!
