I havn't done enough iOS to really speak intelligently about it, but this looks like a great place to start without limiting flexibility.
Although "an extensible open-source
mobile backend framework" seems to say that it also applies to non iOS, it doesn't seem that it does. Is it more suited for iOS, or iOS only?
Many services that Helios provides are either iOS specific backend integrations (Push Notifications & Store Kit transaction verifications) or has client-side components (A/B testing, better client-side networking libraries)
