I like C3 Xcode project export for iOS and being able to directly compile my APK file with C3 because that makes thing so much easier.
I feel that Analytics is as important as Ads and IAP (basic feature) as any serious developers would want to have any sort of data tracking in their app.
I read around and I found out that Scirra needs to whitelist a 3rd party addons / plugin before it will work with the in-built services.
If not, Scirra should consider officially supporting at least one of the Analytics out there (just like with Mobile Advert and IAP).
We won't be creating our own analytics service, since many good ones already exist. There are also already some addons that can integrate them - take a look at the addon exchange.
