Echo: Letters to Future You

Echo is where you keep the thoughts you would otherwise lose.

No folders. No filters. Just capture what is on your mind and keep going.
Use hashtags inline and Echo organizes the rest.

ECHO LETTERS
Seal a thought today. Pick a date six months, a year, or five years from now. When the day comes, your phone delivers it back. Past you, writing to future you.

ECHO WRAPPED
Replay your year as a sequence of cards: how much you wrote, your top tag, your busiest month, your longest streak. Save a card to share, or print the full archive as a PDF.

THOUGHTS THAT COME BACK
Each morning, a forgotten note from weeks or months ago surfaces in your feed. Past you, in quiet conversation with present you.

NEURAL LINKS
New entries connect to related past ones automatically. No setup. Your ideas find each other.

DESIGNED FOR IOS
Home Screen and Lock Screen widgets.
App icon quick actions for new thought, voice capture, and last echo.
Face ID lock for Zen Privacy.
On-device voice transcription using iOS Dictation.
