How do I start a breathing session?
Tap the Breath tab at the bottom of the screen. Choose one of the four modes — Calm, Box, Focus, or Rest — and pick a duration (1, 3, 5, or 10 minutes). Tap Begin to start. The arc on screen fills as each breath phase unfolds. Tap Pause to pause, or End Session to finish early.
What are the four breath modes?
Calm (4-7-8) — Inhale 4 seconds, hold 7, exhale 8. A pattern designed to slow the nervous system.
Box (4-4-4-4) — Inhale 4, hold 4, exhale 4, hold 4. Equal phases, used widely for focus and stress.
Focus (6-2-6) — Inhale 6, hold 2, exhale 6. A lighter hold for sustained concentration.
Rest (4-6) — Inhale 4, exhale 6. Simple two-phase breathing for winding down.
How does the daily streak work?
The Today Arc ring has three segments: intention, session, and mood. Each segment fills when you complete its corresponding action for the day. When all three segments are filled, the arc seals and that day is counted as complete.
The streak number in the centre of the ring shows your current unbroken chain of completed days. The 14-day strip on the Intention History screen shows which of the past two weeks were closed.
How do I set a daily intention?
Tap the intention area on the Today screen, or tap Set today's intention. A sheet appears with a text field (60-character limit), four category chips — Growth, Calm, Focus, Resilience — and a list of phrase prompts for the selected category. Tap a prompt to fill the field, or write your own. Tap Save to set it.
How do I log my mood?
Tap Log how you feel on the Today screen, or open the Log tab and tap the add button. A sheet opens with a five-level arc slider (drag to set your level), eight neutral tags to describe the feeling, and an optional note field (140 characters). Tap Save to record the entry.
Does the app work offline?
Yes. SereneArc is entirely offline. It makes no network connections and has no backend server. All your data — intentions, sessions, mood entries — is stored only on your device. There is no account to create and nothing to sync.
How do I set up a daily reminder?
Open the Settings tab (last tab in the bar). Toggle Daily Reminder on. iOS will ask for notification permission — grant it to enable the reminder. A time picker appears below the toggle; set your preferred time. To cancel the reminder, toggle it off.
How do I delete all my data?
Open the Settings tab and find the Reset All Data row. Press and hold the arc dial on the right side of that row. Keep holding for 1.5 seconds — the arc fills as you hold — until it completes and the reset executes. Releasing early cancels the action with no changes made. This deletes all intentions, sessions, and mood entries from the device permanently.
Is SereneArc available on iPad?
SereneArc is designed for iPhone. While it may run on iPad through compatibility mode, the layout is optimised for a phone screen and the experience is best on iPhone.
Where are my quotes? Can I browse all of them?
The Today screen shows one quote per day, drawn from a curated collection. Tap the quote card to open the full Quote Collection. There you can browse all quotes filtered by category — Growth, Calm, Focus, or Resilience. Today's featured quote is marked with a border.
