For anyone with a someday

You said someday. Then you did it.

A private app for iPhone. Write down what you hope to live, keep what you have lived, and when a plan finally happens, one tap turns it into a memory with the story of getting there still attached.

The trip you keep talking about. The first marathon. The house. The year you don’t want to lose.

If you have a someday you keep meaning to get to, this was made for you. And if you already have years behind you worth keeping, it was made for that too.

From the maker

For years, releasing my own app was something I hoped to do someday. I started more than once, but never made it all the way. Then I began building Once & Someday, an app about turning hopes into lived moments, and realized it had become my own Horizon. This app is the someday I am finally living.

How it works

Plan it. Live it. Keep the whole Journey.

Start with a Horizon and add only the planning that helps. When you live it, tap “I lived this.” It becomes a Moment, with the plan and progress still connected.

Two places to start

Save a Moment or add a Horizon.

Keep the weekends, holidays, celebrations, achievements, and occasional ordinary experiences you want to return to. Add them when they matter to you.

Start with an experience you hope to live. Timing, steps, savings, and updates stay optional.

Make it yours

Choose how your whole archive looks.

Three archive styles. Each one changes the paper, the ink, the colours your categories are drawn in, and the way a photo sits on the page. Choose one when you start. Changing it later is included with Pro.

Coffee by the river

Still

Near monochrome and firm cornered, with one deep red note. Photographs are mounted on a dark plate, the way a print is pressed onto card.

Coffee by the river

Dawn Default

Calm blues, soft edges, and morning light across the page. Nothing frames a photograph, so the picture is the loudest thing on the card.

Bloom

Warm paper, full colour, and generous curves. Every card carries a second impression printed just behind it, like ink that moved.

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 want to experience. It can stay as a someday idea or include timing, steps, and savings. When it happens, “I lived this” turns the Horizon into a Moment and keeps the Journey connected.

Do Horizons have deadlines?

No. Timing, steps, savings, and reminders are optional, and a Horizon never becomes overdue.

Can I undo “I lived this”?

Yes. Undo fulfillment returns the Horizon to its previous active or resting state. You choose whether the resulting Moment stays on its own or is deleted.

What does Once & Someday cost?

The beta is free to try. Free lets you create up to 25 Moments and keep 2 Horizons active, with one photo per Moment and private iCloud sync. “I lived this,” archive export, and restoration stay available even when an archive is above those allowances. Pro adds unlimited creation, richer media, full reflections, Storybooks, and premium widgets. Current prices are shown in the app.

What is a Storybook?

A Storybook is a designed PDF created privately on your device. Choose Signature or Home Movie, then keep, print, or share the finished book wherever you like.

Can I share a Moment or Horizon?

Yes. Choose Signature or Home Movie, then export a 9:16 Story or 4:5 Feed image. Only the image you choose leaves the app.

Is my archive private?

Yes. Your archive stays on your device and syncs through your private iCloud database on both Free and Pro. There is no Once & Someday account.

Can I take my data with me?

Always. Archive export creates a folder with readable JSON and all media stored in your archive. You can restore it later on Free or Pro. Restoration adds missing items without replacing your current versions.

What happens if Pro ends?

Your existing content stays readable and editable. Premium media can still be viewed, reordered, removed, exported, or replaced one-for-one. Private iCloud sync, “I lived this,” archive export, and restoration remain available.

Which devices does it run on?

Once & Someday is built natively for iPhone and also runs on iPad. It needs iOS 18 or later. There is no Android version today.
