What is "crashlytics"

Crashlytics is a Twitter-owned Boston, Massachusetts-based software company founded in May 2011 by serial entrepreneurs Wayne Chang and Jeff Seibert. It has been integrated in over 1 million apps and is one of the most popular Software development kits SDKs.

With Crashlytics, mobile developers for iOS, Android, and Unity are able to pinpoint, down to the exact line of code, the issues that causes their app's instabilities. As of 2016, Crashlytics has been installed on over 2 billion active devices (virtually all active mobile devices) and is the #1 most installed SDK for performance.

In January 2013, Twitter announced it signed a definitive agreement to acquire Crashlytics. The acquisition price was reportedly at over $100 million (about $259.5 million by the time of Twitter's IPO).
