That tightness in your chest is not your fault.
Here is a place to take a breath.
From the moment it hits to the nights you cannot sleep — six gentle ways to cope.
Slow down fast, shallow breaths. Just follow the on-screen rhythm — inhale, hold, exhale. Even when you are hyperventilating, you will always know the next breath.
Come back to the present through your senses. Name what you can see, hear and touch, one at a time, and let a racing mind settle back to solid ground.
50 short lessons that soften anticipatory anxiety. How attacks work, agoraphobia, seeing a doctor, medication, relapse prevention — explained gently, grounded in expert knowledge.
13 public-domain classics, retold for falling asleep. A sleep timer stops playback once you drift off. The audio lives inside the app, so it plays with no signal at all.
Nature, instrumental and healing frequencies. For settling your breath, or for a quiet hour with nothing to do. These play offline too.
Hold a fingertip to the camera for about a minute and read your heart rate variability. Based on the result, the app suggests a way to spend the day.
From calming screens to insights and a doctor-ready report — every one is a real screen.
