A daily companion for iPhone

A little cloud to keep you company through the day.

Caelia follows your day: a slow breath in the morning, a pause at midday, a moment to tell her how it went in the evening, and a softer way into sleep.

Tap her. Or stroke her, slowly.

01 · Your day with her

Four small moments. Never more than a few minutes.

Her colour, her sky and what she offers follow the clock. Each moment fills in once you've done it, and nothing happens if you don't. There are no streaks to keep and nothing to lose.

Morning

Begin softly

A short breath, then your words for today.

“Good morning. I saved you a quiet minute before everything begins.”
Midday

A pause with her

A one-minute reset if the morning got away from you, or a hug and a few kind words.

“Middle of the day. Shoulders down, jaw soft. Better.”
Evening

Tell her about your day

Choose how it felt, then write it down or simply talk to her.

“The day is winding down. What stayed with you?”
Night

Wind down

Slow breaths with long, easy exhales, then goodnight.

“Let the day go. Nothing else is needed from you tonight.”
02 · Her weather is yours

When it rains where you are, she brings an umbrella.

If you allow it, Caelia draws the real sky around her. Rain falls, snow drifts, the wind tugs at her, and in the morning the forecast is how she says hello.

Weather comes from Apple Weather. Caelia only uses your approximate location, only while the app is open, and only if you say yes.

03 · She answers to touch

Tap for hello. Stroke her, and she shows you more.

She squashes, giggles and blushes under your finger. Her home stays quiet and uncluttered until you stroke her slowly, and then four small things appear. You can try it on her up there.

Breathe

She grows as you breathe in and softens as you breathe out. No long breath-holds.

Check in

Tell her how you feel, in a word or a whole paragraph. She listens first.

A kind word

A few words for you, right now. Your words for the day also wait on your Lock Screen.

Play

Catch falling stars or play peekaboo. A minute of play with no levels, no streaks and no losing.

04 · She remembers, gently

She remembers what matters, and only what you allow.

Over the days, Caelia gets to know you a little. She notices a heavy yesterday and starts the morning more gently. She doesn't keep score.

An evening diary

Write, or talk and she keeps it as text. Your days gather in a diary you can read back on your profile.

She learns, if you say yes

Only after one clear yes does she keep short notes from what you tell her, and later ask how things turned out.

The people you love

Mention a birthday and she'll remind you when it comes. On your own birthday, she writes you a letter.

A small wardrobe

What she wears tells you how the day is going.

An umbrella for rain, a scarf for snow, a moon crown at night, a party hat on your birthday. Most of the time, she's simply herself.

Caelia on an open iPhone Duo: the cloud on one side of the fold, the four moments of the day on the other
05 · On iPhone Duo

Unfold your iPhone Duo, and she makes room for your day.

Open it and Caelia settles on one side of the fold, with the four moments of your day on the other. Whatever you open, a slow breath or tonight's check-in, sits beside her, never across the seam.

  • At home in every poseOpen flat, half folded on a table or closed: the layout follows, and nothing resets when you fold or unfold.
  • Within reach on the tableHalf folded, you see her from a distance on the top half, with the controls on the bottom one.
  • The same Caelia, with more roomEverything from your iPhone, with Write, Reminders and your profile right at the edge.

06 · On iPad and Mac

On a bigger screen, she makes room for you to write.

Open Caelia on iPad, or on your Mac, and you'll find a quiet journal: a clean page, a serif you can sink into, and nothing else asking for your attention.

  • Just you and the pageBold, lists and headings with a click or the shortcuts you already know. Focus mode softens everything but the sentence you're writing.
  • The moments of your dayAdd how it felt, where you were, the weather, a photo or a link, right inside the page.
  • Free, private, no AIThe journal costs nothing and no AI ever reads it. iPad and Mac stay in sync through your own iCloud, and with Caelia Pro your iPhone joins them.

08 · Written with care

Words you can actually believe.

Every line Caelia says follows what psychology research says helps, and what quietly backfires. Grand promises can make a hard day feel worse, so she doesn't make them.

“The universe provides.”
“You can take this one step at a time.”

  1. Believable, not grand.“You can…”, “You're learning to…”, “It's okay to…”. Words that still sound true on a bad day.
  2. She invites. She never commands.“Want to breathe with me?” Never “you should”.
  3. She doesn't need you.No guilt when you've been away and no streaks to protect. When you come back, she's simply glad.
  4. Hard days are allowed.She names the feeling, says it makes sense, offers one small optional step, and points you toward the people in your life.
  5. She is not a crisis service.She says so plainly. If you need help now, the app shows a button to call a helpline in your region.
09 · Privacy

Kept on your iPhone. Quiet by default.

Made in Switzerland, by a small team that would rather know less about you.

Your diary stays with you

Your diary, your moods and what Caelia remembers are stored on your device, or in your own iCloud if you sync them. There's no account to create.

Only what a reply needs

When her AI writes to you, it receives only what that one reply needs, such as the entry she's answering, never your whole diary.

You choose

Turn her AI words off in Settings and she speaks from her own hand-written lines. Weather and learning are off until you say yes.

10 · Questions

Good to know.

What is Caelia?

A calm companion for iPhone: a small cloud who keeps you company through the day with short breathing, kind words and a place to tell her about your day. Her name comes from caelum, Latin for sky.

Is it free?

Caelia is free to download. Caelia Pro is an optional subscription that you can manage or cancel at any time in your Apple Account settings.

Does she work offline?

Yes. Her hand-written lines, the breathing and your diary all work with no connection. Her AI replies and the live weather need the internet.

Is Caelia therapy?

No. She's a gentle daily practice, not a treatment and not a crisis service. If you're struggling, please reach out to someone you trust or to a local helpline. The app shows one for your region.

Which languages does she speak?

English, Spanish, Catalan, French, German and Portuguese.

Which devices are supported?

iPhone and iPad with iOS 17.0 or later, and Mac with macOS 26 or later. On iPad and Mac, Caelia is a quiet journal, and Android is coming soon. A Home Screen and Lock Screen widget brings your words for the day without opening the app.

Can I use the stickers in WhatsApp?

Yes, for free. On iPhone, tap “Add to WhatsApp” on the stickers page or in Caelia's Settings › Stickers. On a computer, you can download them and make each one a sticker in WhatsApp.

She'll be there in the morning.

Free on iPhone, iPad and Mac, in six languages. Android is coming soon.
