How it works

The day you say, “I lived this.”

A Horizon is something you hope to live. When it happens, tap “I lived this.” Once & Someday creates a Moment and keeps the reason, progress, and milestones that came before it.

Questions, answered

Before you download.

Can I share a Moment?

Yes. Turn any Moment into a designed image sized for a social feed or story. When a Horizon becomes a Moment, the share card celebrates the milestone and where it began.

What is a Storybook?

A Storybook is a designed PDF created privately on your iPhone. Pro can make one from a completed Journey, a year in reflection, or all the Moments from one place. Keep it, print it, or share it.

Is my story private?

Yes. Your archive begins on your device, there is no Once & Someday account, and optional Pro sync uses your private iCloud database.

Is Once & Someday free to begin?

Yes. Free lets you save Moments, create Horizons, and use “I lived this” when a dream happens. Optional Pro adds unlimited creation, richer storytelling, private sync, and Storybooks.

Begin where you are

Your story is already happening. Keep it yours.

Start with one Moment. Hold one Horizon. Let the story grow from there.
