Does the free version of unity supports these features?

Hi,

Does unity free version support below features?

in-app purchase,
push notifications,
game centre,
and integrating chartboost, admob SDKs?

Can I export my games to iOS, Android, Windows Phone and Amazon using the Unity free version?

Thanks in advance!

There’s no feature difference between pro and free; they’re the same app and have the same features. (Aside from the splash screen). Pro is about services, and is required if you earn >$100K/year. Read this: Powerful 2D, 3D, VR, and AR software for cross-platform development of games and mobile apps.

Yes, yes, yes, yes, yes.
Yes, yes, yes and yes.
