Echo is a personal time capsule for the things you want to remember — and share.
Record a video, voice note, or letter to your future self. Or send a time-locked message to a friend. Choose when it unlocks — tomorrow, next month, or years from now. Once sealed, it can't be opened early. When the moment arrives, your past self has something to say.
WHY ECHO?
Some things are meant to be felt twice. A pep talk for a hard day. A promise you made to yourself. The sound of your voice on a good day. A surprise message for a friend's birthday. A message to open on your wedding, or the day you finally made it.
Echo keeps your most personal moments safe — encrypted, private, and waiting for the right time.
HOW IT WORKS
1. Record — Capture a video, voice note, or write a letter
2. Seal — Choose an unlock date and lock your Echo
3. Wait — Your Echo stays sealed until the moment you chose
4. Open — When the time comes, relive the moment

Ratings & Reviews

- General stability and reliability improvements:
- Reminder notifications now stay accurate to a message's real unlock time instead of drifting.
- Reduced app freezes by moving heavy encryption/decryption work off the main thread.
- Improved recovery from corrupted or unreadable local data files.
- Better handling of interruptions (calls, Siri, backgrounding) during recording.
