I wouldn't use Crashlytics. I use ACRA (https://github.com/ACRA/acra https://github.com/ACRA/acra) for a project that has around 30k active installs. I also wouldn't use Crashlytics due to a study that we've conducted in the last 3 months on 200 of the most used apps in Germany. We have collected real network traffic with a setup consisting of Wireshark and sslsplit (https://github.com/droe/sslsplit https://github.com/droe/sslsplit). We have discovered that Crashlytics will send GPS location data alongside bug reports. Probably it tries to collect as much data as possible.
