Write
Give it a title and write what you want to remember: a letter, a wish, a question for your future self.
A time capsule in your pocket
Seal memories.
Open them later.
Write a letter to your future self, add photos and a voice message, then seal it with wax and choose the day it opens. Until then, not even you can peek.
Free to start · No account · Your capsules stay on your phone
How it works
Three steps, one promise to the future
A capsule is a message that waits. You write it today; it opens on the day you decide.
Seal
Add photos and a voice message, choose the opening date and seal it with wax. From now on it stays closed.
Open
On the day it unlocks you get a notification. Break the seal and read what you wrote, months or years ago.
Features
Everything a memory needs
Photos
Attach the pictures of the moment, as many as you like.
Voice messages
Record your voice: in a few years it will mean even more.
Opening-day alert
A notification reminds you when a capsule is ready to open.
Share by link
Send a capsule to someone: it stays sealed for them too until the same day.
Private by design
No account. Messages, photos and recordings never leave your phone.
Any date you want
In 1, 5 or 10 years, or on a day that matters: a birthday, a graduation.
Inside the app
Made like an old letter
Paper, ink and wax seals. A quiet place for the things that matter.

FAQ
Questions
Can I open a capsule before its date?
No, and that is the point. A sealed capsule shows only its title and opening date. You can delete it, but not read it early.
Where are my capsules stored?
Only on your phone, in the app's private storage. Messages, photos and voice recordings are never uploaded to our servers.
What happens if I change phone or uninstall the app?
Because capsules stay on the device, uninstalling the app deletes them. Keep the app installed until your capsules have opened.
How does sharing work?
The app creates a link with the title, message and opening date. Whoever opens it can add the capsule to their app, where it stays sealed until the same day. Photos and voice messages are not included.
Is Pro a subscription?
No. Pro is a one-time purchase on Google Play that unlocks unlimited capsules.
Is there an iPhone version?
Not yet. Time Capsules is available for Android on Google Play.
