I went through a zombie exam, got "H M M, this sucks, form submission failed. hangs up" Error recovery is a bit, ahem, challenging in a call flow, but you might try to make things a wee bit more graceful. Still, I understand it isn't meant to be immediately productized.
As a product, by the way, this has clear commercial potential. Can I mention again how much Twilio is going to disrupt whole industries?

Nice app. Definitely functional, though I echo sourc3's sentiments to raise the barrier of entry.
Not to be a stickler, but I would remove the TM from your sub-header. Or move it to your app's name.
That isn't a slogan you can trademark, so it's kind of out of place.
Great idea, in case you hadn't noticed...
"Instantly turn any Wufoo Form into a phone survery!" - typo on Survey.
Good luck
This is a great idea! I really think this has potential, but one thing I'd suggest is to pick a vertical and enhance the system further. Because if all you do is integration between two existing services, barrier of entry is pretty low.
I'd suggest either adding more integration points, or developing an add-on service on top of this.
Once you do that, I think you can sell this to many startups including mine in the near future :)
