What's the best Momentum to finance my Start-up? What are the key points that must be in place before opening equity or trying crowd fund it?

There are two sides to that question. One is the mobile app itself and the other is the backend. If I misunderstood in any way and you didn't mean "native" app I apologize in advance. On the backend, there is no clear cut answer to which is the "best". It depends solely on the developers you are able to get. We for example use Node.js , mongoDB, redis, elasticsearch and a couple of proprietary tools in the backend. But you have your pick of the litter now both on the backend api and the datastore with the myriad of options available and touted as the "best" currently on the market. Now on the app side again it solely depends on what you need your mobile app to do. Experiencing first-hand "develop once, run anywhere" I can say it's more like "develop once, debug everywhere" to quote a Java saying. We have tried Phonegap and Titanium Appcelerator and we have switched to native (ObjC and Java) after a couple of months of trying to go the hybrid route. The reasons behind the choice are as follows: - anything that breaks the pattern of how those frameworks NEED to operate is just a huge technical debt that keeps accruing a huge interest. - anything that uses css3 accelerated animations on Android is buggy at best and slow as hell at worst on any lower (< 4.1 I think) versions of Android I hope this gives you some insight.

I've been recommended to speak with Leigh Rowan in the past for iBeacon projects. I haven't had the pleasure of doing so yet but he came highly recommended. His contact information is on his LinkedIn account. https://www.linkedin.com/in/leighrowan

What's the name of the app so we can look at it?

The best way would be to hire an expert on oDesk, etc. which is fairly cheap and also reliable. But It sounds like you want to go even cheaper than that. Try posting on StackExchange, which is free. Another cheap option is to check local Meetup.com tech gatherings in your area and ask some experts directly for free advice. Good luck!

The best avenue for funding would likely be Kickstarter, but that presumes that the idea of a gesture-reading device is likely to have broad-enough appeal, which I'm not sure of based on the one line description. When I think about reading gestures, I think about a market primarily aimed at people with vision impairments. If that's the case, you might even want to look at foundations or organizations who might fund some of the research, but that will almost inevitably slow your pace of innovation. You might want to setup a call with Clay Hebert if you decide to go the Kickstarter route. https://clarity.fm/clayhebert Best of luck. Curious to hear more.
