Write a letter to the person you'll become. Seal it. Then let time do the rest.
Letterseal is a time capsule for your own words. Tell your future self what today feels like, what you're hoping for, what you're afraid of. Choose the day it opens — next month, next New Year, ten years from now — and seal it. Until then, all you'll see is the countdown.
When the day comes, your phone lets you know, and a letter from your past self is waiting.
SEALED MEANS SEALED
Tap a sealed letter and you see how long is left, not what you wrote. You can still read one early, but it takes a deliberate choice, because the waiting is the whole point.
MORE THAN WORDS
• Add a photo of the moment you're writing in
• Not sure how to start? Pick from 42 questions in six themes, from "How are you, honestly?" to the advice you'd give yourself
• Choose a date with one tap: a week, 100 days, six months, a year, next New Year — or any day you like
WHEN IT OPENS
• Reminders the day before and the moment a letter opens
• An opening worth waiting for, with everything you sealed inside
• Write back: reply to your past self and keep the answer with the letter
• Write to your next self straight from the letter you just read
• Save any opened letter as a printable keepsake PDF
ALWAYS IN VIEW
• Home Screen and Lock Screen widgets counting down to your next letter
• Start a live countdown on the Lock Screen and Dynamic Island for the final hours
• A yearly reminder, on a date you pick, to write the next one
LETTERSEAL UNLIMITED
One payment, yours to keep. No subscription.
• Unlimited sealed letters (the free version holds five at a time)
• Voice letters — record up to five minutes in your own voice
• Up to six photos in every letter
• Surprise dates: pick a window and Letterseal chooses the day in secret. Nothing gives it away — not the widget, not the list, not the reminders — until it opens
Everyone who bought Unlimited before keeps it and gets all of the above.
YOURS ALONE
Your letters stay on your phone. There's no account to create, no server, and nothing is tracked or analysed. Lock the app with Face ID if you share your phone. Move your letters to a new phone with a password-protected backup file that only you can open. One switch keeps letter names off the Lock Screen, widgets and notifications.
