Yesterbook: Diary into Books

Turn everyday moments into a book worth reading again.

We think the big moments will stay with us. Later, we discover that what we miss most are the ordinary days we thought we would never forget.

Yesterbook is a private journal that grows with time. What you write today is sealed after 24 hours. Each month, your entries become a personal magazine, automatically laid out with a cover, contents, and thoughtfully arranged words and photos—a real publication, quietly waiting on your bookshelf.

◆ Write it down. Leave the rest to time.

· Write multiple entries a day. Drafts save automatically, so interruptions needn't break your flow.
· Add photos, eight moods, places, and weather to give each day its context.
· Edit each entry for 24 hours after writing it. Then the original is permanently sealed and can no longer be changed.
· Keep adding annotations after sealing—a conversation between your future and past selves.
· Add entries for past dates, giving remembered days a place in your book.

◆ A new edition, every month

· At month's end, your entries automatically become a personal magazine with a cover, contents, and pages arranged around your words and photos.
· Browse your bookshelf. Edition by edition, watch the years unfold.
· Export beautiful A5 / A4 PDFs and print a real book for your future self. Membership is required to save and share PDFs.

◆ Find yourself across time and place

· Calendar: photo tiles and mood colors bring the days you recorded into view.
· Places map: revisit your world, with entries grouped by city and location.
· On This Day: meet the person you were in years past.
· Search entry text and annotations to find even the smallest memories.

◆ No shutdown worries. Keep writing for years.

· Local-first storage keeps your journal on your devices.
· Sync uses Apple's official iCloud service, with no third-party or self-hosted sync servers.
· Writing, reading, and syncing need no connection to our servers.

A journal is something you keep for years. Your words stay on your own devices and in your private iCloud, ready to be written with peace of mind and treasured for years to come.

◆ Privacy is essential to a journal

· Sync automatically across iPhone, iPad, and Mac through your own private iCloud account.
· Journal data travels only between your devices and your iCloud, never through our servers.
· Face ID / Touch ID support, with an automatic privacy shield when the app enters the background.
· Deleted entries stay in the trash for 30 days, leaving room to undo a mistake.
· No ads. No analytics SDKs. Your words belong to you.
