How is this different from using the tel: URI scheme and making a cross-platform app to handle that? Sure, I don't need to know your phone number anymore, but now I have to know your Toky URL and to download their app.
Exactly. Just get a call forwarding service, you can even use Google Voice, and embed tel: URIs in your website to that number. You get the same benefit (no one gets your actual number, as additional ones as well (voice mail, forwarding to different numbers on a schedule, etc).
I think the idea of the creators was to make people independent from a telephone company, no need to even own a SIM card..
Love that you don't have to download anything. I've been trying it out from my browser and it's pretty neat.
It's strange to have a demo for a voice chat system with no audio track.
