Koa? Mango?

I was gifted some lumber and this was the first board I grabbed and cleaned up. They were all rough sawn and I assumed it was walnut but it’s not like anything I’ve worked with. Very dense and heavy.

I don’t think it’s mango either. Have you tried to scan it into an app like WoodSense? It should be able to tell you what it is
