Frequently Asked Questions
Is Bugsnag better than Sentry for mobile apps? +
For native iOS and Android apps, Bugsnag is generally considered better. Its App Stability Score, release health tracking, and mobile crash grouping are purpose-built for mobile workflows. Sentry has capable React Native and iOS/Android SDKs, but the mobile-specific features and dashboard experience are more polished in Bugsnag.
Does Sentry support React Native error monitoring? +
Yes. Sentry has a first-party React Native SDK that captures JavaScript errors, native crashes, and performance traces. It integrates with Expo. For React Native specifically, Sentry and Bugsnag are both strong options — the choice often comes down to whether you need Sentry's web/backend integration or Bugsnag's native mobile depth.
How does Bugsnag's App Stability Score work? +
Bugsnag's App Stability Score is the percentage of user sessions that experienced zero crashes in the selected time period. It is visible on the Bugsnag dashboard per app version. A score above 99.5% is generally considered stable for production apps. The score makes it easy to set release quality gates — only ship when stability is above a defined threshold.
