Once a year we let our imagination go wild during our annual hackweek event. It’s where we come up with product updates, design them, and implement prototypes.

Our mobile engineering team came up with the idea to develop and ship a mobile application that focuses on monitoring release metrics like crash-free users & crash-free sessions. We wanted to give developers a concise but comprehensive view of whether a release was healthy, erred, or experienced abnormal crash sessions across multiple projects.

Because we wanted to bring this to both iOS and Android and only had a week to build a proof of concept, we decided to build the app in Flutter. Naturally, there were bugs. But we were ready for them.
