Can you offer any sort of guidance on what cold start times currently look like? I know it depends on how much code is being loaded and interpreted, but it's obvious you're a really dedicated PM, and I know that—as a result—you must have a qualitative sense of what the perf looks like.

For background: I maintain OneBusAway for iOS, and am investigating options for sidecar data (e.g. how delayed is a bus, is there still room on it, etc.). Ideally, this would all be part of the core OBA API, but that may not be an option. I'd just use Apple's CloudKit, but I want to be able to process incoming data and share the data between iOS and Android. Hence my interest in your product :)
