Best Debugging Apps for iPhone

Sentry is an application monitoring and observability platform that helps developers identify, diagnose, and resolve software issues across web, mobile, backend, and AI-powered applications. Designed with a developer-first approach, the platform combines error monitoring, performance tracing, logs, session replay, profiling, metrics, and uptime monitoring into a unified environment connected by a single trace. Sentry enables engineering teams to quickly move from issue detection to root cause analysis and remediation, providing deep visibility into application behavior and user experiences. Its AI-powered debugging capabilities help developers identify underlying causes, generate fixes, and prevent regressions before code reaches production.

Reports arrive to you instantly, automatically supplemented with a ton of useful data so you can fix them 50X faster. Whenever users notice a bug, they just shake their phone to report it, without ever leaving your app. When they shake their device, Shake opens up and allows them to send you feedback without ever leaving your app. Report yourself any info from the user’s device you want. Use .setMetadata() to easily adjust the data to your debugging requirements. See the user’s taps around your app, .log() custom events and see all their network traffic prior to reporting the bug to you. On the web Dashboard you can, for example, effortlessly find only bugs reported from iPad Airs that were in landscape mode and offline. Get bug notifications immediately in your team chat. Or, have tasks created directly in your issue tracker of choice. Shake was built to play nicely with the tools your team already uses.
