Cyclic Sighing is a dedicated physiological sigh app for iPhone. It is designed specifically around the physiological sigh technique — also called cyclic sighing — a double inhale through the nose followed by a long exhale through the mouth.
Unlike general breathwork or meditation apps that include the physiological sigh as one exercise among many, Cyclic Sighing is built entirely around this single technique, with mood tracking tied directly to every session.
Best for: Anyone looking for a focused, dedicated app for practicing the physiological sigh — beginners, people exploring the breath-mood connection, and anyone building a daily breathwork habit around a single clear technique.
The physiological sigh is a breathing pattern characterised by a double inhale — a full first breath in through the nose followed immediately by a shorter second inhale — and then a long, slow exhale through the mouth. The exhale is roughly twice the length of the two inhales combined.
It is also called cyclic sighing. The two terms describe the same breathing pattern.
A deep, full breath in through the nose.
A short, sharp top-off inhale at the top of the first breath.
A slow, extended exhale through the mouth — roughly twice the total inhale length.
The physiological sigh is a general wellness practice. It is not a medical treatment or therapy for any condition. Consult your healthcare provider before starting any breathing practice if you have a health condition.
Cyclic Sighing is a focused breathing trainer and practice tracker built specifically around the physiological sigh.
Smooth animations and optional voice guidance walk through each inhale and the extended exhale. Subtle haptics mark phase transitions — no need to watch the screen.
Calm (2:1:6), Relax (3:1:8), and Rest (3:2:10) — all following the same double-inhale, long-exhale structure. Custom timing lets you adjust any session to fit your schedule.
A pre-session check-in captures how you feel before breathing, and a post-session check-in tracks whether that changed. Every mood entry is tied directly to the session around it.
A monthly calendar and yearly overview visualise your mood patterns — worse, same, or better — filterable by feeling. See whether your practice and mood tend to move together.
Weekly, monthly, and all-time views show sessions, cycles, and duration. Daily streaks with Skip Day protection support consistency without punishment.
Time-based and location-based reminders. A nudge at the office, gym, or whenever a sigh tends to help most.

Log completed sessions as Mindfulness minutes in Apple Health if you choose to. Optional and requires your permission.
