Ask HN: Test iPhone app on mobile Safari?

How do you test an iPhone app idea on the mobile browser on real people's iPhones?

I'm looking for a way to test our iPhone app MVP with 10+ friends before we go through all the App store setup, without the UDID hassle.

Three options I looked into:

1. Testflight - We find there is a subtle but significant difference between "testers" and "MVP customers." We don't feel too comfortable imposing future customers with the UDID hassle -- not to mention that we'd like to test core features of the app before going full-on with iOS development. https://testflightapp.com/

2. Pieceable - Viewer is Flash based and doesn't run on mobile Safari. Works with desktop browsers. https://www.pieceable.com/

3. Kickfolio - Embedded iFrame is based on Pieceable Viewer, same story. http://kickfolio.com/

The app will have small set of features but it needs to function with 10+ user accounts. Before we build an html-based demo of the app, I'd appreciate it if anyone has other suggestions. Thanks!
