How do you get people to use it?

Like let's say I have drinks plans with my friend, and I want to bail using this service. How to I tell her to install the app?

Wouldn't asking her to install it be pretty rude? It would basically be saying "Hey, FYI I like to bail on stuff a lot. So you probably shouldn't make any plans involving me."

I could see that stigma as a critical roadblock against growing the kind of user-base you'd need for this to get popular.

Do people send calendar invites when hanging out with friends?

Personally, if a meetup did actually make it into my calendar, I would not ship it to a friend.

I did wonder that. Personally, I put social events in my calendar but don't specifically invite the other people to it. I'm still validating the concept, but am initially leaning towards this being more of an integration with calendar services, particularly facebook where people probably do have common invites

I've only used FB events among friends for big events (Lets all go to Vegas!) and even then most of the coordination happens in a chat group.

I've literally never had that happen, personally. That doesn't mean it doesn't happen, though.

i saw the tweet as well. if you want some help designing and researching UX and flows, let me know.
