A Moment worth keeping
The climb was only half the story
The view mattered. Reaching it together mattered more.
The Once & Someday difference
The memory keeps the dream that came before it.
Most apps keep a wish or a memory. Once & Someday keeps the living connection between them.

Questions, answered
Before you begin.
What is the difference between a Moment and a Horizon?
A Moment is something you lived and want to keep. A Horizon is something you hope to experience someday, are working toward, or are saving for. When it happens, “I lived this” turns the Horizon into a Moment and keeps the Journey connected.
Do Horizons have deadlines?
No. A Horizon can have a gentle season, a next small step, or a check-in preference, but it never becomes overdue. Dreams do not expire.
What is a Storybook?
A Storybook is a designed PDF created privately on your iPhone. Choose Paper, Botanical, or Night, then keep, print, or share the finished book anywhere.
Is my story private?
Yes. Your archive starts on your device, there is no Once & Someday account, and optional Pro sync uses your private iCloud database.
Is Once & Someday free to try?
Yes. The TestFlight beta is free to try. Optional Pro adds unlimited creation, richer Journeys, reflections, Storybooks, premium widgets, and private iCloud sync.
Begin where you are
Your story starts with one thing.
Keep something you lived, or hold close something you hope to experience someday.
