Monitor what matters in your React Native app
We help large teams build visibility into their React Native apps. Our solutions focus on capturing the right metrics, reducing blind spots, and enabling fast, reliable decision making across platforms.
Where observability breaks down in React Native apps
React Native applications combine JavaScript and native code, making monitoring and debugging more complex. Without a clear strategy, teams struggle to detect issues early, track user impact, and maintain release quality across versions.
Too many layers, not enough visibility
JavaScript, native code, and backend systems are owned by different teams. Without shared observability, it’s hard to trace bugs or performance issues end to end.

Different issues on different devices
User experience depends on geography, OS version, device type, and network quality. Without proper segmentation, real problems stay hidden in the noise.

Too much noise, not enough signal
At scale, you get thousands of metrics, logs, and traces—but most of them don’t help you ship faster. Without a clear strategy and right KPIs, it’s hard to focus on what matters.

Building scalable observability for a high-growth React Native app
For a fast-growing finance platform with 60,000+ active users, we consolidated fragmented monitoring into a unified, scalable observability system.
By introducing custom performance tracking and stabilizing their test infrastructure, we helped the client detect incidents faster, improve release quality, and enable reliable performance insights across their React Native mobile app.
3→1
analytics systems unified into a single interface
Observability built for scale, not just debugging
Go beyond logs and crash reports to build a complete picture of your app’s health—from user experience to system-level signals.
Real User Monitoring
Track actual user experience across devices and geographies—capturing startup times, screen transitions, and user flows with real context.
DMAIC
Use structured root-cause analysis to define, measure, analyze, improve and control (DMAIC) performance over time—not just react to incidents.
Vendor-agnostic monitoring
We build a vendor-agnostic observability layer with standards like OpenTelemetry—unifying metrics, traces, and logs across platforms (Datadog, New Relic, Sentry, etc.) for real-time insights into your app’s health.
Platform-wide coverage
Instrumentation across native code, JS runtimes, and backends—bridging gaps across iOS, Android, and web for true end-to-end visibility.
CI/CD integration
Monitoring embedded into release pipelines—surfacing issues early, gating releases, and linking metrics to code changes and test runs.
Custom dashboards
Dashboards and alerts focused on business-critical signals—tracking what actually matters instead of flooding teams with noise.
Learn how to use data to improve app performance and user engagement
With real user data, you can uncover performance bottlenecks, track regressions, and validate improvements.
In this talk, we show how to go beyond raw collection—measuring startup times, screen interactions, and conversion flows—to make technical decisions that directly improve app reliability and user experience.
Turn fragmented monitoring into unified observability strategy
Establish observability for React Native at scale
Lay the foundation for monitoring across JS and native code, enabling your team to capture real performance, errors, and user behavior from the moment you release the app.
Unify metrics, traces, and logs across platforms
Break down silos between mobile, backend, and infrastructure—bringing all critical signals into a single, connected system.
Connect observability to release workflows
Integrate with CI/CD to track regressions, detect release-impacting issues early, and ship with higher confidence.
Define meaningful KPIs and alerting standards
Align metrics with business goals, build dashboards that matter, and establish clear thresholds for incident response.

FAQs
Setting up observability in React Native apps isn’t always straightforward. These are the most common questions we get from teams looking to improve performance visibility, connect monitoring to releases, and act on what they see.
We help you define what to track—performance, errors, user flows—and implement tooling across JS and native code, so you start with meaningful, production-ready signals.
Yes. We integrate with tools like Datadog, Sentry, New Relic, or your internal stack via OpenTelemetry—so you don’t have to start over.
We surface key signals (like startup time or error spikes) during testing and rollout, link them to specific builds, and configure thresholds to catch regressions before they reach users.
We help you go beyond crashes—focusing on metrics like startup time, screen load speed, interaction delays, and retention-impacting issues tied to real usage.
Yes. We trace behavior across boundaries—e.g., from a JS interaction into a native module and back—so you get a full picture of what caused an issue.
Yes. We support both apps built entirely in React Native and those that embed React Native within an existing native codebase—whether it’s just one screen or a larger part of the app.
Absolutely. Even if React Native powers a single flow or feature, observability helps catch issues early and ensures that part of the app meets performance and reliability standards.
Need to understand, monitor, and improve your app in production?
We help you build a complete observability setup for React Native—tracking real user experience, linking issues to releases, and setting clear KPIs that drive action. From first signals to long-term performance strategy, we’ve got you covered.
