Great idea! But 3$ is really way to cheap, even at the current 9$/month I'd just have signed up without thinking twice! Why? Because I know how much value a tour provides my app/my revenue!
I already have a simple tour in Bunker App but it is really a PITA so I've postponed doing improvements to it. I have hopes that your software helps me, and if it does, it's totally worth some money for me!
I've just signed up for your mailing list, I hope I'll get into beta to test it soon. My app is a JS-heavy, single HTML page app so I'm curious to see how Taurus works with my app.
