Caelia is a calm companion for iPhone: a diary that listens back, daily affirmations you can believe, and one slow minute of breathing when the day gets loud.
Download on the App StoreHer sky follows your clock. Tap her, or stroke her slowly.
Her colour, her sky and what she offers follow the clock. Each moment takes a few minutes, and nothing happens if you skip one. No streaks to keep, nothing to lose.
A short breath, then your words for today.
“Good morning. I saved you a quiet minute before everything begins.”
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.”
Choose how it felt, then write it down or simply talk to her.
“The day is winding down. What stayed with you?”
Slow breaths with long, easy exhales, then goodnight.
“Let the day go. Nothing else is needed from you tonight.”
Each evening Caelia asks how today went. Write a few lines or just talk to her, and she answers warmly. Some nights a single line of gratitude is enough.
Every morning she has a few words for you: daily affirmations written to still sound true on a bad day. They wait on your Home Screen and Lock Screen widget, too.
“The universe provides.”
“You can take this one step at a time.”
When anxiety climbs, breathe with her. She grows as you breathe in and softens as you breathe out, with no long breath-holds.
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.
Open Caelia on iPad or Mac and you’ll find a clean page, a serif you can sink into, and nothing else asking for your attention.
