Yes, Hansel.io allows you to diagnose crashes and issues as well. We have an extremely capable technology that provides you with stack traces and device/OS/memory conditions at the time of crash. Crashlytics and other diagnostic solutions also provide largely the same. They are great products themselves, which have been perfected over the years with additional niche use cases. However, the power of Hansel starts where Crashlytics and other diagnostic solutions end.
We let you act on these issues and crashes, right there and then. Not through updates. Not later. NOW.
