Write a letter to your future self

Seal your first capsule
This is the whole idea, in miniature: write something true about today, pick a date, seal it. In the app, the real one comes back to you.
How it works
Write it today. Read it later.
A capsule takes about two minutes to write and years to finish. That gap is the magic: you keep living, and one day your past self taps you on the shoulder.
Write what's true today
A letter of any length — plus up to six photos, a voice note in your own voice, and the exact spot on the map where you wrote it.
Seal it until a date
Days, months or decades ahead — a birthday, an anniversary, "10 years from today". Sealed capsules stay blurred: only the countdown shows.
Open it when it unlocks
On delivery day the capsule opens — your words, your voice, the place, exactly as they were. Written July 15, 2025. Opened July 14, 2026.
Why Futura
A real time capsule, not another journal
Sealed means sealed
Once a capsule is locked, its words and photos blur out until the open date. No edits, no early looks — just a countdown. Honesty on the way in, goosebumps on the way out.
"You made it. Sunglasses on, coffee in hand — you've earned this one."— the kind of note that comes back a year later
Say it in your own voice
Record a voice message and hear yourself — literally — years from now.
Remember where you were
Each capsule can pin the place it was written. Some letters belong to a park bench.
For you, or for someone
Address a capsule to yourself or a friend — a wedding day, an 18th birthday, "open when".

Frequently asked questions
What should I write in a letter to my future self?
Cover four things: how your life actually looks today (the ordinary details fade fastest), what you're worried about right now, what you hope will be true by the time you read it, and a few questions for your future self to answer. Pick a specific open date — one year and five years are the most common. Learn more →
How do I make a digital time capsule?
Collect what defines this moment — a written note, a few photos, a voice recording, the place you're at — put it somewhere it can't be edited or peeked at, and set a fixed open date. A time capsule app automates the sealing and the delivery. Learn more →
What is the best time capsule app?
It depends on what you're sealing. For email-only text letters, FutureMe is the long-running default. For a true multimedia capsule on iPhone — photos, voice notes and location sealed behind a no-peeking lock — Futura is built for exactly that. See the full comparison →
What are open when letters?
A set of notes you write in advance for someone, each labeled with the moment to open it — "open when you're sad", "open when you miss me", "open on your graduation day". The right words, waiting at exactly the right moment. Learn more →
Is Futura free?
Yes — writing and scheduling text letters to your future self is free and unlimited. A one-time premium upgrade adds photos, voice messages and location to your capsules. Get it on the App Store →
Can I open my capsule before the delivery date?
No. Once sealed, a capsule stays blurred and locked until the date you chose — you only see the countdown. That's deliberate: knowing you can't peek is what makes writing honest and opening it worth the wait.
Can I send a time capsule to someone else?
Yes. A capsule can be addressed to yourself or to a friend — write it now, add their name, and it unlocks on the date you chose: a wedding day, an 18th birthday, a graduation. Ideas for letters to others →
What can I put inside a capsule?
A written letter of any length, up to six photos from your gallery or camera, a recorded voice message, and the exact location where you sealed it. Together they preserve the moment far more completely than text alone.
What do I write in a time capsule letter to my child?
Describe who they are right now — the words they mispronounce, what they're obsessed with, how it feels to be their parent this exact week. Add your hopes, one piece of honest advice, and photos or a voice note. Seal it for a milestone birthday. Learn more →
What goes in a couple time capsule?
Letters to each other, a photo from an ordinary day, a voice note saying what you love about each other right now, and predictions about your life together. Seal it for an anniversary and open it together. Learn more →
Future you is going to read this one day
Two minutes today. Goosebumps in a year. Write your first letter now — it's free, and the best open dates are the ones you pick while you still remember why.
