Crashlytics
Crashlytics is a popular tool that helps mobile app developers track and fix problems in their apps. Think of it as a digital detective that tells developers exactly when and why an app stopped working on users' phones. When an app crashes, Crashlytics collects important information about what went wrong and sends detailed reports to the development team. This helps them fix problems quickly before they affect too many users. It's now owned by Google and is part of their Firebase platform, which is a larger set of tools for creating mobile apps. When you see Crashlytics mentioned in a resume, it usually means the candidate has experience with making mobile apps more reliable and stable.
