Hi, I work at Twilio and can answer questions about Notify. Notify is predominantly a REST API you could access through server-side helper libraries in your favorite language. We have SDKs for Notify as well that provide additional functionality (like the ability to notify the user on the device they were last active one.)

To associate a number (or push registration) with a user you create a "binding"

Maybe i'm missing something but isn't this just like Urban Airship? Basically you need to have an app already in production, and you push through Twilio instead of directly hitting APNS. I do understand the benefits of having a 3rd party manage expired device tokens and sending broadcast push, etc. but having a hard time understanding what's novel about this.

Notify has two unique components compared to other tools in the market. First it is multi-channel- you can send push yes, but also global SMS and notifications into messaging apps like Facebook Messenger, Viber, and WeChat. Second, Notify provides orchestrations- fan out, fall back (push first then SMS if not received), notify on last active or current active device, etc. The fact that Twilio acts as a registrar is something that was highly requested from our customer base.
