Twitter’s Crashlytics announced the launch of Velocity Alerts, which are designed to alert app developers about the most critical issues happening in their apps so they know when they really need to take action ASAP.

For the alerts, they combine your app’s crash data with usage analytics from Answers, the mobile analytics tool added to Crashlytics a couple years ago.

“Now, once you’ve enabled Answers as part of Crashlytics, our system will proactively check to see if there is a statistically significant number of sessions that have ended due to a crash related to one issue on a particular build,” writes Jason St. Pierre on the Crashlytics blog. “If so, we’ll let you know if that issue is a hot patch candidate and needs your attention immediately right on your dashboard. You’ll also get an email alert in your inbox as well as a push notification if you’re using the Fabric mobile app (Android support coming soon). With Crashlytics, you’ll never miss a critical bug!”

Notification emails have also been redesigned to make important information more clear and actionable.
