Yes, I love that sun graph as well. I keep hoping to find an open source mobile app that has something like that.
Currently I use Suntimes (https://github.com/forrestguice/SuntimesWidget/releases) and the only thing I feel is missing is one of those sun graphs. I'd contribute one myself but I feel like it's a bit outside my wheelhouse at the moment.
