Come back to your breath with Espir, a beautiful, minimal breathing experience with no unnecessary clutter. Just what you need to begin: breathe. Choose the practice that fits your moment: start with today’s recommendation, return to your latest technique, or explore seven breathing rhythms. Each session guides you phase by phase with clear cues to inhale, hold, exhale, and rest. What’s included: • 7 breathing techniques: resonant, relaxing, deep box, equal, yogic, box, and energizing. • Short 1, 3, 5, or 10-minute sessions. • A recommendation that follows the time of day and your favorites. • Visual guidance with the current phase, remaining time, rhythm, and completed cycles. • Optional ambient sound and Tibetan bowl cues. • Subtle haptic feedback at each phase change. • Local progress for your minutes, sessions, and practice days. • Favorites and preferences stored on your device. No account, connection, or personal data is required. Use Espir for a morning reset, a pause between tasks, a mindful transition, or a quieter wind-down before sleep. Always breathe within your comfort level. Stop and return to your normal breathing if you feel dizzy, pain, or discomfort. Espir is a general wellbeing tool and is not a substitute for professional medical advice.
