Number Crunch: Facebook Integration
Where can I find Facebook integration?
On the Android platform, you can find Facebook integration on your account settings page.
Facebook Login is the only Facebook integration in Number Crunch Android.
On the iOS platform, you will not be able to find Facebook integration, since it has not been added there.
We don't use Facebook Login, Facebook Share, Facebook Like in Number Crunch iOS
