The best part about Sunrise was Meet, its quick little method of booking meetings with someone: https://sunrise.am/meet

You'd choose some available times, it gives you a link which you send to whoever you want to meet with, and the recipient books a time slot with a couple of clicks. It updates in real time so if you book something new, the slot disappears. It even has a little iOS keyboard to generate these links.

Does anyone know a similar replacement service? Nothing beats just pasting someone a link and letting them pick one of three times you chose.
