Nice work and a nice idea, but I'm struggling to see how it's worth $2 per month when it offers very little over a reminder in Google Calendar. Have you though

Nice work and a nice idea, but I'm struggling to see how it's worth $2 per month when it offers very little over a reminder in Google Calendar. Have you thought about tying up with Google Calendar's appointment slots and automatically connecting your user to the recipient during a free appointment slot in that day?
