Yesterself

The journal that writes back.

Every journal ever built asks you to write into a void. Yesterself makes the void write back — a two‑minute daily correspondence with the only person who has been there for everything.

You were worried you'd made the wrong call. You hadn't. You just hadn't told anyone yet, and carrying it alone made it feel bigger than it was.

— From you, five months ago
The app

Real screens, not mockups.

Every image below is the app running — the morning mail, a letter opened, the desk at night, and the archive underneath it all.

The morning mailbox: a sealed cream envelope postmarked yesterday, above the line “Two letters this morning.”
Morning — mail is waiting
An opened letter rendered as a page of typeset prose, with its postmark and date.
A letter from yesterday-you
The composer, headed “To tomorrow-you”, with an optional prompt chip above the writing surface.
Evening — you write back
The archive timeline grouped by month, with filter chips for voice, hearted and postmarked letters.
Everything you've ever written
The daily loop

Two rituals. Four minutes.

One in the morning, one at night. That's the whole product — and it's designed so a missed day costs you nothing.

Morning · about a minute

Your mail arrives

A small stack of envelopes: the note you left yesterday, a time capsule that has come due, an entry from this day in a past year, and one letter that resonates with how you've been writing lately — with a reason you can check.

Evening · about two minutes

You write back

Speak it or type it. Any sentence can be postmarked to a future date — next Monday, your birthday, a year from now — and it will arrive then, whether or not you remember writing it.

Three promises

The rules we don't break

The mail never goes silent

Miss a day, a week, a month — an envelope is still waiting. There are no streaks to break, and no counter of things you failed to do. Only a number that grows: the days of your life that are in here.

Your archive is never hostage

Export everything, free, always, in formats you can read without us. Paying unlocks syncing between your devices — never access to your own writing.

Billing never surprises you

A plain-language notice before the trial converts, and again before every renewal, saying exactly what you'll be charged. One tap to cancel. No weekly plan, ever.

Privacy

We cannot read your journal.

Not "we promise not to." Cannot. This is an architectural fact, and it's the reason the app is built the way it is.

  • Everything runs on your phone. Transcribing your voice, finding the letter that resonates, writing your yearly retrospective — all of it happens on the device. No cloud AI ever sees a word you wrote. (One honest footnote: Android 10 and 11 cannot confirm that their speech recognizer stays offline, so on those phones the app tells you and asks before it transcribes anything.)
  • Encrypted before it leaves. If you turn on syncing, letters are encrypted on your phone with a key only you hold. Our server stores sealed envelopes it has no way to open.
  • No account, no email, no password. Nothing to phish, nothing to breach, nothing to sell.
  • No analytics, no trackers, no ads. Not now, not later — it's written into the product's permanent non-goals.
Pricing

Free is genuinely usable.

The free tier isn't a demo with the good parts removed. It's the whole daily ritual, forever.
