SYM BREATHING A simple way to slow down, breathe evenly, and find a calmer rhythm. Sym Breathing guides you through a balanced 5.5-second inhale and 5.5-second exhale using smooth visual, audio, and haptic cues. This slow, even rhythm is commonly known as coherent breathing or resonant breathing. Choose a session length, tap the breathing sphere, and follow along. No complicated routines. No overwhelming controls. Just a simple breathing practice you can return to whenever you need a few quiet minutes. GUIDED BREATHING, YOUR WAY Follow the expanding and contracting breathing sphere, listen for gentle audio cues, feel subtle haptic feedback, or combine all three. Choose the guidance that works best for you and your surroundings. A SIMPLE, BALANCED RHYTHM Sym Breathing uses a 5.5-second inhale and 5.5-second exhale, approximately 5.5 breaths per minute. The app keeps the rhythm for you, so you can focus on breathing instead of counting seconds or watching a clock. CHOOSE YOUR SESSION Select a breath count for a defined practice or choose an open-ended session and breathe for as long as you like. DAILY AFFIRMATIONS Begin with a daily affirmation that offers a brief moment of positive reflection before your breathing practice. NIGHT MODE Switch to a warm red interface for a softer visual experience in low-light environments or before bed. LISTEN TO YOUR OWN AUDIO Keep listening to music, ambient sounds, podcasts, or other audio while you breathe. Adjust the breathing cue volume independently to create the experience you prefer. COHERENT BREATHING Slow, balanced breathing practices are commonly used for relaxation, mindfulness, stress management, and supporting autonomic regulation. Research has also explored resonant breathing in relation to heart rate variability, or HRV. Sym Breathing makes this practice easy to follow by guiding each inhale and exhale for you.
