dSYM and Proguard upload failures
Missing symbols produce unreadable stack traces. We integrate dSYM upload into the Xcode build phase and Proguard mapping upload into the Gradle release task — automated, not manual.
Sentry Crash Reporting Tracing Release Health
Sentry Integration Services for Crash and Performance Monitoring
Know about crashes before your users report them. Sentry captures symbolised iOS crash reports (dSYM), Android Proguard-deobfuscated traces and JavaScript source-mapped errors in one unified view — with release health, performance spans and alert routing to Slack or PagerDuty.
We integrate Sentry into iOS, Android and web apps for clients who need production observability beyond what the app store crash reporters show. Sentry's SDK captures breadcrumbs, user context and performance spans alongside the error — so you see not just what crashed, but what the user did before it crashed. We configure dSYM upload for iOS, Proguard mapping upload for Android and source map injection for JavaScript, then define alert rules and triage workflows that route the right issues to the right engineers.
Challenges
Industry challenges we solve
Alert noise from known non-critical errors
Sentry surfaces every error including expected ones, creating alert fatigue. We define ingest filters, fingerprint overrides and alert rules that route only actionable issues.
Performance tracing overhead on mobile
Sentry's auto-instrumentation adds 2–5 ms to every network request. We configure traces-sample-rate per environment and exclude synthetic and internal traffic.
PII in error payloads
Stack traces and breadcrumbs can contain user IDs, emails and request bodies. We configure scrubbing rules and data-scrubber patterns before deploying Sentry to production.
Release health tracking across multiple environments
Staging and production sessions mixed in one project create noisy release health data. We configure separate Sentry environments with distinct DSNs and release prefixes.
GDPR and data residency
Sentry processes crash data on its servers. For EU clients, we use Sentry's EU region (Frankfurt) and configure the SDK's beforeSend hook to scrub PII before transmission.
Solutions
Solutions we build
Crash reporting and symbolisation
Automatic dSYM upload for iOS, Proguard mapping for Android and source-map injection for web — readable stack traces from day one.
Release health monitoring
Session tracking, crash-free user rate and adoption curves per release — catch regressions before they reach the majority of users.
Performance tracing
Frontend to backend distributed tracing — see the full request span from a mobile tap through your API to the database query.
Alert routing and triage workflows
Slack, PagerDuty and Jira integrations with filter rules that route the right issue to the right team, not every error to everyone.
PII scrubbing and data compliance
beforeSend hooks, server-side scrubbing rules and EU-region deployment to meet GDPR requirements for crash data processing.
Custom dashboards and issue ownership
Team ownership rules that automatically assign issues to the right squad, with custom dashboards for release health and error rate SLOs.

FAQ
Sentry FAQ
How does Sentry differ from Firebase Crashlytics?
Sentry covers mobile crashes, web JavaScript errors, backend exceptions and distributed performance tracing in one platform. Crashlytics focuses on mobile crash reporting and release health. Sentry provides more detailed breadcrumbs, custom context, and integration with the rest of your stack — at the cost of a paid plan at scale.
How do you ensure readable stack traces on iOS?
We integrate sentry-cli dSYM upload into the Xcode build phase as a post-action. Every production build automatically uploads symbols — no manual step, no unreadable traces.
Can Sentry be self-hosted?
Yes. Sentry has an open-source self-hosted option (Docker Compose). We configure and maintain self-hosted Sentry for clients who require on-premises crash data storage for compliance reasons.
How do you prevent PII from appearing in Sentry?
We configure beforeSend hooks to scrub known PII fields (email, phone, user IDs in URLs), set up server-side data-scrubber patterns and use Sentry's EU region for processing. Any sensitive fields that slip through are caught in the PII audit we run before going to production.
How do you reduce alert noise in Sentry?
Fingerprint overrides to group similar errors, ingest filters to drop known non-critical errors (network timeouts, cancelled requests), alert conditions with minimum event counts and issue owners to route issues to the right team automatically.
Does Sentry work for React Native and Flutter?
Yes. Sentry provides official SDKs for React Native (with Hermes source maps) and Flutter (with dSYM/Proguard upload). We configure both platforms within the same Sentry project with separate environments.
How do you handle GDPR when using Sentry?
We use Sentry's EU-region deployment (Frankfurt), configure the SDK's beforeSend hook to scrub PII before transmission, set data retention to the minimum required, and document Sentry as a data processor in your GDPR record of processing activities.
