This looks like a cross between OkHTTP and a jobqueue (like https://github.com/WhisperSystems/jobmanager or https://github.com/yigit/android-priority-jobqueue).
But I think this is the first cross platform framework that does this.

I'm not sure about Realm..But I was talking in context of the job manager and network libraries.
But I suppose you could SQLite as cross platform.
Since Realm is available for iOS, Android and Linus from one code base(and open source, so you could port it to other platforms) I would definitely term it as being cross-platform.
