About this app

THE WORLD IS YOUR TIME CAPSULE. LEAVE YOUR MARK.

Echo is a revolutionary geo-locked memory sharing tool. Turn any real-world location into a digital vault for voice logs, photos, and messages. Whether it’s a hidden birthday surprise at a local park or a secret mission for friends across the city, Echo lets you plant memories exactly where they happened.

HOW IT WORKS: THE ECHO CYCLE

1. PLANT YOUR MEMORY Arrive at your location and open the Echo interface. Record a high-fidelity voice log, snap a photo, or write a hidden message. Echo captures the precise GPS coordinates to "lock" the memory to that exact spot.

2. GENERATE THE SIGNAL Once your memory is planted, Echo packages it into a secure, portable .echo file. This file contains the "DNA" of your memory—only accessible to those who hold the file and stand at the coordinates.

3. SHARE OR STORE THE HUNT You are in total control of the signal.

Share via any App: Send your .echo files instantly through WhatsApp, Telegram, Messenger, or Email.

Save to Storage: Save your memories directly to your phone's internal storage. Move them to an SD card, upload them to your private cloud, or keep them as a digital backup for years to come.

4. TRACK THE SIGNAL To unlock a memory, a recipient simply opens the .echo file from their chat app or import it in the app form their phone's internal storage. The Tactical Radar then activates, pulsing and vibrating as they get closer to the hidden location. Only by physically arriving at the coordinates can the memory be revealed.

KEY TACTICAL FEATURES

Precision Radar: A high-tech, compass-driven interface that guides you to hidden coordinates with haptic feedback and proximity glows.

Decentralized Privacy: We don’t store your memories on a central server. Your data stays on your device or in the files you choose to share.

Voice Logs & Media: Attach authentic audio recordings and photos to any real-world location.

File-Based Memory System: Open .echo files directly from chats, downloads, or your internal storage folders.

Offline Ready: The radar and memory-opening logic work wherever GPS is available—no constant internet connection required once you have the file.

WHY ECHO? Echo isn't just an app—it's a tool for digital explorers, secret-keepers, and creators. It’s for the friends who want to leave secret messages, travelers bookmarking the world, and anyone who believes some memories are worth hunting for.

READY TO START THE HUNT? Download Echo today and plant your first signal. The world is waiting to be discovered.
