There are lots of apps out there to choose from, @MarcusJubin, but it's almost impossible to suggest any in particular as this very much depends on your own personal interests and the way you use your phone.

You'll be pleased to know that Bixby is continually improving and now has many more features than it did at the initial launch. Give it a whirl, you never know what you might discover!
