Signal

An iPhone app for the question every outage feed forgets to answer: what actually changed?

01 / Why I made it

A live incident does not need another feed. It needs an edit.

Signal started with a simple frustration: outage reporting repeats itself. Ten posts can describe the same failure while the one useful update disappears between them. I designed the app to group reports into one situation, then surface only changes in impact, place, confidence or recovery.

What this is

A complete SwiftUI prototype with deterministic local scenarios.

What it is not
