A letter on a park bench
Leave something tender for one person, exactly where it means the most. It waits, quietly, for them.
Some messages only open in one place.
Tether ties a private message — your words, photos, a voice note — to a spot on the map and a moment in time. It stays sealed until the person you left it for is standing right there.

Opens 25 Dec
A small ritual, in three moves.
Step 1
Anchor it
Drop a pin on the exact spot. Choose who it’s for, and the window when it’s allowed to open.
Step 2
Seal it
Write it, add photos, record your voice or a short video. Keep it private, or leave it for anyone to find.
Step 3
It opens on arrival
When they’re there — the right place, the right time — it unlocks. Not a second before.
For the things worth returning to.
A trail across a city
Link Tethers into a Journey that leads someone from one place to the next — a story told in footsteps.
A memory left in the open
Publish a Tether for anyone who wanders close to discover — a small gift to strangers and the place itself.
Feel the moment it opens.
A Tether stays locked — showing only how far away you are — until every condition is met. Walk closer and watch it happen. In the app, your own footsteps do the walking.
- Location is checked only at the unlock — never tracked or stored.
- Content is encrypted until the right person, place and time line up.
- Replay it whenever you’re back, for as long as it stays online.

Questions, answered.
How does Tether know I’m there?
Your browser shares your location only at the moment you try to unlock, to check you’re close enough. It isn’t tracked or stored beyond that check.
Is my message really private?
Yes. Content is encrypted and never revealed until every condition — the right person, place and time — is met.
What can I put in a Tether?
Text, photos, audio and video. A quiet note, or a whole memory with sound and motion.
What’s a Journey?
Several Tethers linked together, leading someone from one meaningful place to the next — a trail you design.
Does the recipient need an account?
No. Invite them by email and they’ll be walked through a quick signup, with your Tether already waiting in their inbox.
What does it cost?
Making a Tether is free. Richer or longer-lasting ones cost a few credits, bought as you go. There’s no subscription.
Leave something worth finding.
Start with one place, one message, one person. It’s free to make your first.
