We use this excellent icon set throughout our app on all our platforms. It's fun to work with, well documented, and it is offering all the icons we need (and growing!). It also features 5 different styles for each icon, making if very adjustable to various contexts and situations.

Capacitor allowed as to use the same codebase as our web and desktop platforms, and having to write almost no native code along the way. That way, we can reuse and share vast amounts of components and functions between our different platforms and not write any duplicate code – it's magic!
