The mobile apps team at New Relic uses a combination of New Relic Mobile and New Relic APM 360 with custom Synthetics scripts to ensure high levels of app performance by monitoring API dependencies, running scripted API tests, and setting up synthetic checks that provide real-time insights into app reliability. By using these tools, they can identify potential issues early, resolve them quickly, and ship mobile apps that are highly performant for their users. The team shares a Synthetics script on GitHub to help other developers manage and respond to changes made by other teams' APIs.
