More time with the friends you already have
Share the things you want to do with friends who have chosen to hear from you. Post a Saturday hike, a casual dinner, or a half-formed idea. They reply if they want; saying nothing is always fine.
Who this is for
If you're the friend who plans things
You do most of the inviting, even when reaching out feels heavier each time. Perihelion takes the social tax off the ask: you share one personal link, approve the friends you know, and post when you have a plan. There is no public profile directory and no audience to build.
If a friend invited you
You choose whose plans you want and how often email should arrive — right away or in one quiet daily digest. The organizer approves the connection. Reply “I’m in” or “Maybe” when you want; silence is a complete answer. SMS is planned, but remains unavailable until it is approved and enabled responsibly.
How it works
Three small steps
1
Subscribe to people you want to hear from
An organizer shares a personal Perihelion link. Friends opt in, choose immediate email or a daily digest, and the organizer approves people they know.
2
Post things you're doing
Post an activity at one of three commitment levels: “just an idea,” “I’ll go if you will,” or “I’m going — join me.” Friends hear about it by email on the schedule they chose. SMS will come later, after approval. Never a group thread.
3
Go do the thing
People who want to come tap "I'm in" or "Maybe." Anyone who doesn't reply doesn't reply. You close the tab and go meet up.
Why this is different
Not another social network
Bring your own friends
Perihelion isn't for finding new friends from scratch. It's for spending more time with the people you've already met. If you want a friend-finder, this isn't it.
Built to be left
No feed to scroll. No streaks to maintain. No notifications begging you back. The whole point is to make a plan and go do it offline.
Saying no is easy
Three commitment tiers — "just an idea," "I'll go if you will," "I'm going — join me" — let casual hangs travel as casually as the invitation suggests. Declining is the default. Saying yes means yes. Saying nothing is fine.
