Why you cannot download yet

Our builds are finished and gated, but they are not yet signed with a publicly-trusted certificate. Windows would present them as an unknown publisher. We are not shipping software that teaches you to click past the warning that protects you. Releases open the day signing is in place.

Why we built it

Our whole operation runs on Twilio, and there was no decent handset app for it.

  • The ones we found were hard to look at and awkward to use.
  • Most could not send a text at all, which makes a business line half a line.
  • None of them behaved like the phone itself.

So we took a phone app and a messaging app, built them into one, and taught it to speak Twilio properly. It is also the piece that ties the rest of the ecosystem together.

What it does

Your Twilio number, on a real phone, with real messaging.

Calls and texts on one line Voice and messaging share the same number and the same history. It is not a dialler with the messaging left out.
A real handset app On Android it registers as your actual Phone, Messages and Contacts app, so it behaves like the phone rather than something you have to remember to open.
No forwarding The line lives on the handset over data, instead of being forwarded to a mobile number you also have to pay a carrier for.
Released as one product Desktop, mobile and browser ship together or not at all, so the three never drift apart.
Known limit

In active build. Every release must ship across all three platforms together.

We list these because you will find them anyway. A limitation you learn about after paying is a defect in how we sold it to you.
