Mobile Vitals - Four Metrics Every Mobile Developer Should Care About

Slow apps frustrate users, which leads to bad reviews, or customers that swipe left to competition. Unfortunately, seeing and solving performance issues can be a struggle and time-consuming. Most developers use profilers within IDEs like Android Studio or Xcode to hunt for bottlenecks and automated performance tests to catch performance regressions in their code during development. However, testing an application before it ships is not enough.

Troubleshooting Feature Flags with Komodor and Sentry

Komodor is a Kubernetes-native platform we’ve created to streamline troubleshooting. It was born out of frustrations we felt as developers, when we were required to waste hours of our time on troubleshooting, instead of focusing on what we really wanted to do - creating and innovating. Komodor sits on top of your K8s cluster and integrates with every existing tool you have, be it CI/CD, repo, monitoring, alerting, or communication.

Sentry's New Mobile App for Managing Releases

Once a year we let our imagination go wild for a whole week during our annual Hackweek event. It’s where we come up with product updates, like dark mode support, design them and implement prototypes. The mobile engineering team came up with the idea for a Sentry mobile app that focuses on Release Health. We wanted to give developers a concise but comprehensive view of if a release was healthy, errored, or experiencing abnormal crash sessions across multiple projects.

Using Feature Flags with Komodor and Sentry

Toggle on. Toggle off. Feature flags are enabling developers to deploy with confidence, safe in the knowledge that they can always disable buggy features in production without changing the code. While this increases the speed, stability, and frequency of software updates, it’s no magic trick and still requires planning in advance and using the right tools.
