You · Sunday
Found a walk that reminded me of our campus route. The chai wasn’t quite as good.
A private friendship journal
Stay close to your friends, even when life moves on.
Arbor helps you stay in touch with the friends you already have. Remember what matters to them, keep the moments you share, and get a gentle reminder when it’s time to reach out. What you write stays on your phone.
Private beta on iPhone and Android · Not yet in the App Store or Google Play

Starting a new job this week. Ask how it’s going.
Start with one friend.
What the beta does today, in three small steps.
Add your people.
Type in a friend’s name, or choose them from your contacts on iPhone. Add a birthday and the things you don’t want to forget.
Keep the moments.
Note a call, a message or a coffee together, so you can see when you last caught up and what you talked about.
Get a gentle nudge.
Set a follow-up, a regular rhythm or a birthday reminder. Arbor reminds you; it never messages your friends.
Every friendship has its own roots.
In Arbor, your circle is a small forest. Each tree is a friendship, and the moments you keep become part of its history—a place to return to what you’ve built together.
A quiet week doesn’t erase your roots.
Private by design.
The app has no account and no sync, and it sends nothing to us. Your people, notes, moments and reminders stay on your phone, in an encrypted database, unless you export a backup or share something yourself. You can lock Arbor with Face ID, your fingerprint or your passcode.
A backup is a readable file, so keep it somewhere you trust. Joining the waitlist on this website is separate: we keep your email address to write to you about Arbor, as the privacy notice explains.
Planned · not in the beta yet
Less “we should catch up.” More little moments.
Different cities. Busy weeks. Another call that never quite happens. Later, we want Arbor to help two friends share small moments that fit better.
Sunday postcards
One photo and a few lines from your week. Something your friend would otherwise miss.
We’re exploring a browser reply, so a friend could answer without installing the app.

That made me smile. I passed our old spot last week too.

A rhythm that fits real life.
We’re exploring suggestions for a manageable next step, based only on what you choose to share. You decide what feels right. Your friend decides whether to join.
Illustrative suggestions
Different time zones
A voice note they can hear when their day slows down.
A crowded week
One photo instead of a long call.
Ready for more time together
A short catch-up around something you’ve shared.
The beta has no AI and sends nothing off your phone. If suggestions arrive later, we’ll say how they work; the moments will always come from you.
Make room for your people.
Arbor is in a small private beta. Join the waitlist and we’ll email you when we can invite more people to try it on iPhone. We’re testing on Android with a few people too.
We’ll email you about Arbor and early testing. Every email has a link to remove yourself. Privacy notice
Questions
What is Arbor?
A private friendship journal for your phone. It helps you remember what matters to the people you care about, notice when it’s been a while, and stay in touch with friends in a way that fits your life.
Who is Arbor for?
People who want to stay close to friends they already have, especially when distance or busy schedules make it harder. It isn’t for meeting new people, and it isn’t a contact manager for work.
When can I try it?
Arbor is in a small private beta, by invitation: on iPhone through Apple’s TestFlight, and on Android as a test build shared directly with a few testers. It isn’t in the App Store or Google Play yet. Join the waitlist and we’ll email you when we can invite more people.
Is what I write private?
Yes. The app has no account and no sync, sends nothing to us and never contacts your friends. What you write stays on your phone, in an encrypted database, unless you export a backup or share it yourself. A backup file is readable, so keep it somewhere safe. The waitlist on this website is separate: it stores your email address so we can write to you.
Does my friend need the app?
No. Arbor is just for you, and the people you add never see anything. Sharing small moments with friends is something we’re planning for later.
Why a forest?
Each tree represents a friendship and the moments you’ve shared. Different friendships grow at different rhythms.
