## What is Echo?

Some things are worth saying in a particular place.

Echo lets you leave a message pinned to a spot on the map — a bench, a summit, a doorway — and seals it there. The person you left it for can see that something is waiting, but not what it says. The only key is being there.

When they arrive, it opens.

LEAVE ONE WHERE YOU ARE STANDING

Stand at the place and tap once. Echo takes the spot from your phone's GPS, so the message is pinned to where your feet actually were, not to a guess on a map. Write what you would say if you were there, choose how close they have to get, and seal it.

OR LEAVE A TRAIL OF THEM

A trail is several places in order. Each stop carries a clue that leads to it and a message that opens on arrival — and the next clue only appears once the last one is found. Walk the route yourself, stamping each stop as you go.

Good for a birthday, an anniversary, a city someone is visiting for the first time, or a walk you want to take with someone who is not there yet.

WHAT HAPPENS TO YOUR LOCATION

Echo checks where you are at the moment you try to open something, and then forgets it.

The check happens on the server, so a message cannot be opened early by changing anything on your phone. What is kept afterwards is how far away you were and how accurate the reading was — never the position itself. Echo never builds a history of where you have been, because it never stores where you were.

Location is used only while the app is open. There is no background tracking.

GETTING A MESSAGE

Anyone can open a message left for them. They do not need an account, and they do not need this app — a link works in a browser. The app makes the walk better: GPS on a phone is far more accurate than a mobile browser's, so it opens where a browser would still be searching.

FREE, WITH AN OPTIONAL PREMIUM

Leaving messages and walking trails is free. A free message goes to one person, carries a voice note of up to 90 seconds, and stays for 30 days.

Echo Premium lifts those limits: up to 10 recipients, voice notes up to 5 minutes, photo attachments, and messages that do not expire.

Echo Premium is US$6.99 per month or US$69.99 per year; the price in your own currency is shown before you buy. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. You can manage the subscription and turn off auto-renew in your Apple Account settings after purchase.
