Example of Good Cross-Platform App but Native UI

Wondering if there are any good examples of apps that work cross-platform but are designed using the native platform's standard UI patterns.

Many apps are often specific to one OS, such as sketch. Two that I can think of that are cross-platform are slack (mac and windows) and chrome (mac and windows). However, slack mostly doesn't use the native UI except for the window border, and chrome is a get-out-of-the-way app so it doesn't really use too much.

Other cross-platform apps that I don't think use the native UI much are the Adobe Creative Suite apps, for example. They have their own style that is uniform across platforms (e.g. photoshop for windows).

Wondering if there are any nice examples of apps that take full advantage of the native UI space and make a cool design from it that is both well-fit to the native platform, while also keeping uniform with the brand. It seems easier to just ignore the native UI and build your own uniform style system, but I'd like to see if there are examples where they actually made it work well using the native UI features.
