I know there are many SDKs, and I have boiled my choice down to a select few: phonegap, appcelerator, ionic, and maybe xamarian (but it's pretty pricey).
My use case is pretty simple: talk to a middleware server and implement about 4 features with different sets of json data. What's the platform that will allow me to get this out the fastest (ideally a month to 8 weeks)?
The app does have to be production quality though...this is a consulting gig for a small company.
