From sign-up to seeing a friend, in five steps.

Always just you and one friend. Nothing is public.

1. 01

   Sign up

   Your email and a 6-digit code. Add your home city and birth date — CATCH UP! is 18+.

2. 02

   Add a friend

   Send a crew request or share your invite link. They join your crew only when they say yes.

   They get an email and a browser alert about your request.

3. 03

   Switch on your porch light

   Free right now? Go live. Your crew sees it for up to two hours, then it switches off by itself. Travelling? Add the trip so they know you're coming.

   Friends with alerts on hear the moment it goes on.

4. 04

   See the overlap

   When you're both free, or in the same city on the same days, it shows up. Ask to catch up — only your friend can answer.

   Your ask lands in their inbox, by email and alert.

5. 05

   Chat

   Once you've both said yes, a private chat opens. Just the two of you — pick the place and go.

   Replies show up in your Inbox and by alert.

Alerts follow your choices: “Email me the good stuff” and “Alerts on this device” on your You page. An evening digest rounds up the day, at most once.
