Circadia: Breathe & Sleep

Wind down in a few calm steps: slow breathing, a quiet body scan and letting go of your thoughts, with soft noise that fades out on its own. No account, no ads, and Circadia itself sends nothing anywhere.

Circadia is a quiet evening routine for sleep, mindfulness and rest. Open it at bedtime, follow the steps and let the day go.

TONIGHT

One tap starts Tonight: 3 calm steps in about 5 minutes. Two minutes of 4-7-8 breathing, a moment to let go of your thoughts, and one short reflection for the night. A greeting that fits the time of day welcomes you, and you can add your first name if you like. After Goodnight a black rest screen follows, and the soft noise fades out by itself within 30 minutes.

BREATHING

Follow a soft, guided circle through three techniques:

- 4-7-8: inhale 4, hold 7, exhale 8

- Slow exhale: 4 seconds in, 6 seconds out

- Box breathing: 4 seconds in, hold, out and pause

Choose 2, 5 or 10 minutes and pause at any time. Eyes-closed cues give a gentle vibration for each phase, and 4-7-8 and Box can switch to a black screen, so you can breathe with your eyes closed. Your session history stays on your device, and you can clear it whenever you like.

BODY SCAN

Ten steps from head to toe, about 7 minutes. The screen stays dark, a soft vibration marks each step and there is no sound. The screen can turn off while you listen to your body.

SOFT NOISE

Brown noise, pink noise or rain, one tap away on every screen, with its own volume. The sound is generated on your phone, keeps playing with the screen off and shows a quiet notification with a stop button. After Goodnight in Tonight it fades out by itself in 30 minutes, and the sleep timer works the same way.

STARS, BEACH, COSMOS AND NIGHT

- Stars: trace your finger along real constellations such as the Great Bear, Orion and Cassiopeia, or switch to random patterns.

- Beach: draw patterns in the sand with your finger, then smooth the sand and start again.

- Cosmos: drift slowly past the Sun and the planets in 3D. No facts, no reading, just calm movement.

- Night: ten of our own short reflections for the end of the day. Swipe up through them, mark favourites and share the ones you like.

THOUGHTS

Type or speak what is on your mind, using your phone's speech recognition, and watch it drift away like clouds, then let go.
