 # Crashlytics
 
 `Crashlytics` is a lightweight, real-time crash reporter that helps you track, prioritize, and fix stability issues that dismantle your app's quality. It delivers fast and precise information about crashes and helps you gain insights into your app's performance so you can pinpoint the exact line of code your app crashed on. Crashlytics offers a comprehensive suite of features like crash analysis, issue aggregation, and tracking user activities that led to a crash. This tool is now a part of Google's `Firebase` platform but can also be used independently.

 # Remote Config
 
 Firebase Remote Config is a cloud service offered by Firebase. It lets you change the behavior and appearance of your app without requiring a new app release. By using Firebase Remote config, you can customize your app for different user segments, manage the core aspects of your app by modifying parameters externally, and conduct A/B tests to improve your app. It works efficiently by using default values that control the behavior and appearance of your app. When your app needs configuration information, it makes a request to the Firebase Remote Config server. If the server has updated values, these values replace the default ones, hence modifying the app's behavior or appearance according to your needs.
