Custom Event Tracking
for Mobile Apps
Track purchases, signups, and any business action — then filter your session replays to watch exactly what happened. Vexo enriches every event with screen, device, and user data automatically.

- Separate code for user identification
- Missing context requires debugging guesswork
- Per-event pricing that scales unpredictably

- Automatic context — screen, device, location added for you
- Built-in user attribution — see who triggered each event
- Simple function call — just import and track
- Flat-rate pricing — predictable costs that scale

Custom Event Tracking FAQ
Common questions about custom event tracking for React Native, Expo, and mobile apps.
- What is custom event tracking in mobile app analytics?
- Custom event tracking lets you measure specific user actions in your mobile app—purchases, signups, feature usage, or any business-critical interaction. Unlike automatic tracking, custom events give you control over exactly what to measure and what metadata to include. Vexo makes custom event tracking simple for React Native and mobile apps with automatic context enrichment.
- How do I add custom event tracking to a React Native app?
- With Vexo, adding custom event tracking to React Native is straightforward. Once you have the SDK installed, import the customEvent function and call it anywhere: `customEvent('purchase-completed', { amount: 99.99 })`. Vexo automatically enriches your event with screen name, device info, app version, and location—making React Native analytics effortless.
- Can I filter session replays by custom events?
- Yes! This is one of Vexo's most powerful features for mobile app analytics. You can filter session replays by any custom event to watch exactly what users did before and after triggering that event. This makes debugging mobile app user issues much faster—you see the full context of user behavior around any business event.
- Does Vexo custom event tracking work with Expo?
- Yes, Vexo fully supports Expo apps with Development Builds. Custom event tracking works identically in Expo as in React Native CLI projects. Simply install vexo-analytics, add the initialization, and use customEvent() anywhere in your Expo app. This makes Vexo the ideal analytics solution for Expo developers.
- How does Vexo compare to Firebase for custom event tracking?
- Unlike Firebase Analytics, Vexo provides automatic context enrichment for every custom event—screen name, device info, location, and app version are added without extra code. Vexo also offers session replay filtering by event (which Firebase lacks), user attribution, and flat-rate pricing. For React Native apps, Vexo is purpose-built while Firebase is a general-purpose tool.
- What user behavior data is captured with custom events?
- Vexo automatically enriches every custom event with: the screen where the event occurred, device information (OS, model, screen size), app version, user location, session context, and timestamp. You can also add custom properties. This lets you track user behavior in your mobile app with full context for every event.
- Can I see which users triggered each custom event?
- Yes! Vexo's user attribution feature shows exactly which users triggered each custom event. Click any event to see user profiles, session history, and the full context. This is essential for understanding mobile app user behavior, debugging issues, and identifying your most engaged users.
- How do custom events work with mobile app funnel analysis?
- Custom events are the building blocks for funnel analysis in Vexo. Track events like signup-started, profile-completed, and first-purchase to build conversion funnels. Vexo shows drop-off rates at each step, and you can click through to session replays to understand why users abandon your mobile app funnel.
- Is there a limit to custom events in mobile analytics?
- There's no limit to the number of unique custom event types you can define in Vexo. Your plan determines total event volume (automatic + custom combined). The free tier includes 100,000 events per month—perfect for mobile startups. Premium plans scale to handle enterprise mobile apps with billions of events.
- Do custom events work across React Native and web?
- Yes, custom events work identically on React Native (iOS/Android) and web applications. Track the same events across platforms and see unified analytics in one dashboard. This lets you compare user behavior across mobile and web, track cross-platform user journeys, and understand your full product analytics picture.
