I wonder how effective this method compares to that of using something like binaural beats.

I'd certainly like to work on it if it went open source.

All my work is via Git. So in my team we use GitHub for our normal projects (pay per project), and when we're done, I put it onto BitBucket (pay per user), so whatever I put onto BitBucket is then free of charge. I think I'll stick to this solution as it's cheap (read: free).

However, if I was to use your service, I'd be happy to use command line.

Yeh, I think it's definitely looking more like Sublime Text.

Well of course all that is done before all of the developing of the app. The idea is to reduce the amount of uncertainty by not creating a full blown app that has had a lot of time and money put into it, when some of the features aren't helping in terms of getting new customers, keeping old customers and bringing any value to the product/service.

Yes, TestFlight is absolutely great for beta testing.

However, in the startup sense, it's not exactly beta testing, it's testing the market, so beta testing would be fine to test something you've built works, but by no means will show what people will think of the app/product.
