At Superhuman, we're building the fastest email experience in the world. As we've pushed iOS to its limits, we've had to dive into the deepest internals of UIKit.

This is how we detect and communicate network status as part of making Superhuman the fastest and most reliable email experience in the world.

Superhuman's goal is to make you brilliant at email, anywhere and everywhere you are. Imagine you’re out and about — on a plane, in a café, or the back of an Uber. Packets drop, requests fail, and latency is high.
