Most breathing apps ship one or two fixed patterns. This composer lets you set inhale, hold, exhale, and a second hold independently — and breathes you through it with a synced visual ring. Pattern length from 8 to 60 seconds total.
Most breathing apps assume everyone needs the same thing — usually 4‑7‑8 or box breathing. That isn't true. Some people calm down with longer inhales (activating the sympathetic brake). Others need a long exhale to vent the chest (boosting parasympathetic tone). Some find any hold unbearable. The composer lets you tune it to your nervous system in 30 seconds, instead of accepting a one‑size pattern.
Not for: active medical events (chest pain, fainting, severe shortness of breath) — those need urgent care.
There's no score here — the output is your own body's report. Three honest signals to look for: (1) Has your breathing rate dropped? You'll feel the spaces between breaths widen. (2) Has your jaw or forehead softened? That's the muscle signal of sympathetic drop. (3) Is your attention still on the ring, or has it begun wandering? Wandering is the goal — it means you've stopped scanning.
A breathing rhythm is a regulator, not an eraser. It cannot undo the stressor that triggered the wave, and it is not a treatment for panic disorder, PTSD, generalized anxiety disorder, or any clinical anxiety diagnosis. If breathing work reliably makes you more anxious, that is information: talk to a clinician. Some people's dysregulated systems interpret slow breathing as a threat — a known response that warrants professional support.
Because the four phases do different jobs. Inhale expands the lungs and gently stimulates the sympathetic system; a top hold locks air in; a longer exhale is the most reliably calming phase; a bottom hold is optional. Custom ratios let you match the pattern to your state instead of guessing.
Two to five minutes is enough for most regulation. Going past ten minutes without a real need can produce dizziness or a sense of effort. If you want a longer practice, switch to a slower everyday activity (a walk, a stretch) instead.
You're not doing it wrong. Some nervous systems read deep, slow breathing as a threat (it mimics the early breath pattern of certain panic attacks). Stop, ground through your feet instead, and consider speaking with a clinician about your breathing sensitivity.
