Firebase A/B Testing

Firebase A/B Testing helps you test different variations of your app to understand what works best for user engagement and retention. Firebase A/B Testing comes in handy if you want to optimize features, UI elements, or app performance by testing different versions and gathering data on what performs best.

Firebase Cloud Messaging (FCM)

Firebase Cloud Messaging (FCM) allows you to send notification messages to users thus driving user engagement and retention. It is perfect for sending push notifications, reminders or other in-app messages.

Firebase In-App Messaging

Firebase In-App Messaging helps you to send targeted, contextually relevant messages within the app that encourage app exploration and discovery. It can be used when you want to deliver realtime, in-app messages to users to encourage actions like completing a profile, completing an order, etc.

Tools for Releasing and Monitoring

App Distribution

Firebase App Distribution is a tool for distributing you app to beta testers and collaborators before releasing it to the public.

Firebase Crashlytics

Firebase Crashlytics enables you to achieve realtime crash and error reporting to track and fix app crashes, improve stability and enhance user experience. Firebase Crashlytics can be used to identify and troubleshoot app crashes, allowing you to prioritize fixing bugs and ensuring smoother user experiences.

Firebase Performance Monitoring

Firebase Performance monitoring helps you to monitor your app’s performance by tracking metrics like app startup time, network requests, and slow views. It can be used to ensure optimal app performance, diagnose issues like slow load times, and improve user experience by resolving performance bottleneck

Test Lab

Test Lab is cloud-based automated app testing environment that lets you test your application on a variety of real devices and configurations in order to gain insight on how it will perform with real users. Test Lab enables you to identify issues before release thus ensuring that your app functions as expected across different devices and OS versions.
