A private app for long-distance couples
Where are you two?
Two Lights is a private little world for two people far apart: every photo, voice note and song flies across one sky, from your city to theirs. Tell us your two cities and see yours.

- Free while we build it
- Only you two
- Two cities and an email
Look around the demo while you think about it.
We let couples in a few at a time and make each sky by hand. No newsletter, never shared. How we handle it.
See how it worksHow it works
Leave something small. It crosses your sky, and it stays.
Not messages: things. Each one is made into a small paper object, flies from your city to theirs over the real sky above each of you, and waits on their Today, closed until they open it. Then it’s kept on a globe of every city you were apart in.
Write
Sent now, it’s folded into a paper plane. Kept for later, it’s sealed in a letter until the day you choose, or until you’re home.
Photo
A print of whatever’s in front of you. Or bagged and labelled as evidence, for the €9 sandwich.
Voice
Your voice, the wind, the tram behind you: something to play on their walk to work.
Song
A song for right now, with a line about why. It joins your mixtape.
Postcard
From wherever you are today, stamped and postmarked with the city, and a new stop on your globe.
Want to see your own two cities under one sky?
Two real skies
Rain in Amsterdam, a soft evening in Chicago.
Each side of your sky is the real one above each of you: the time, the weather right now, the temperature in the units you grew up with. A small paper pet wanders the line between your two lights. And when you both photograph the sky on the same day, it notices, and sets the two side by side as one.

What you’ll have when you’re home
A scrapbook that makes itself.
Everything you left, laid out week by week as a book to page through, each of you in your own handwriting. It grows while you’re apart, and it’s finished the day you’re both home. Made on your phone; nothing is uploaded to make it. Every song you send goes on one mixtape, a side each.

And a mixtape
Every song, on one tape.
Side A is every song one of you sent, Side B the other’s, with the line you wrote for each on the insert. Press play for a preview of each; flip it over for the other side.

Keep the chat for the forty-times-a-day stuff. This is the other thing, where all of it is still waiting when you close the gap.
Why we made it
We made Two Lights for ourselves, living in two cities a long way apart. The chat held the day-to-day. Nothing held the rest: a photo of the sky we were both under, a song for a walk home, a letter meant for the day we’d be together again. So we made a place for it, and now we’re making one for you.
Questions
What is Two Lights?
A private app for long-distance couples. You leave each other small things (a thought, a letter sealed for later, a photo, your voice, a song, a postcard) and each one flies across one sky, from your city to theirs. Over the months it becomes a globe of everywhere you were apart, a scrapbook, and a mixtape of every song you sent. When you’re together again, letters sealed until you’re home open, and everything stays.
We’re in the same country, on the same clock. Is it for us?
Yes. Distance isn’t only time zones. Each of your skies follows the real sun over your own city, so one of you can still be watching the sunset while the other’s is already dark, and each side shows its own weather. When your clocks match, the time shows once, between you. Nearby cities aren’t lost on the globe either: it moves in close enough to tell them apart.
Who can see what we leave?
Only the two of you. Each sky is walled off from every other couple, there’s no feed and nothing public, and we don’t look at what you leave unless you ask us to fix or delete something. Everything is backed up, encrypted, every week, and end-to-end encryption is on its way. You can ask us to delete your sky at any time.
What does my person need to do?
Nothing yet. When your sky is ready, you’ll get a link that opens it, and one to send them. They sign in with their email, by a link or a six-digit code: no password, no app store, nothing to install first. It works in the browser on iPhone and Android, and added to the Home Screen it opens like an app, with a quiet note when something arrives.
More questions
What does it cost?
Nothing while we build it with the first couples. If that ever changes, you’ll hear first, and everything you’ve made stays yours.
Why is there a waitlist?
We let couples in a few at a time and set up each sky by hand, so every one starts right. Asking takes your two cities and an email.
Can I give it as a gift?
Yes. Tick “It’s a gift for my partner” when you join, and your sky is set up for giving: you start it, and send your person their link when you’re ready to give it.
Ask for a sky for the two of you.
Two cities and an email. We’ll make the rest by hand, and send you your own link when it’s ready.
