Breath & Frequency Trainer

Bring breath, sound, and geometry together with Breath & Frequency Trainer.

The app guides you through timed breathing patterns while a responsive geometric visualization expands and contracts with your breath. Add an optional sine-wave frequency tone and customize your session to create a breathing practice that suits you.

Choose from several built-in breathing patterns, including Box 4–4–4–4, Coherent 5–5, 4–7–8, and Out-hold 8–6–8–10, or create your own custom inhale, hold, exhale, and bottom-hold sequence.

Combine your breathing session with selectable 432 Hz, 528 Hz, 639 Hz, or 852 Hz tones, or enter your own custom frequency. You can adjust the volume, turn sound on or off, and choose whether the tone maintains a constant volume or follows the intensity of the breathing visualization.

The animated geometric visual provides a simple visual reference for each stage of the breathing cycle, expanding during inhalation and contracting during exhalation.
