After spending $49 on a crappy baby shower invite sending tool I’m glad to hear this. Could save a lot of people a lot of money! Hopefully it works for non Apple users too.
The organizing people ecosystem is a mess. It's nice to see something new.
What’s missing when sending invites via mail, or a message on a social media they’re in?
You need to know your friends' addresses for mail. For both, you have to send out invites individually. People want to make a list of names and phone numbers and send out a blast. They then want a low-effort, centralized place to receive and manage RSVPs.
