Inner Balance™ gets your heart, mind, and emotions in sync for greater calm, focus, and a more balanced you in everyday life. HEARTMATH® SENSOR REQUIRED: This is the companion app to the Inner Balance sensor. It requires one of the HeartMath Inner Balance sensors (e.g. Bluetooth® or the Inner Balance Lightning sensor), which connects to your device and clips to your earlobe to pick up your heart-rhythm pattern. Inner Balance™ is a system of software and sensor that helps you strengthen your inner balance through training, guidance, and self-observation. It supports you in bringing your heart, mind, and emotions into a balanced, focused state (coherence), which you create yourself through calm breathing and positive focus. More than 400 independent, peer-reviewed studies have been published on HeartMath technologies and methods. Inner Balance gives you a real-time coherence score as feedback, and guided meditations and dynamic graphics support you toward a calmer, more centered, and more focused state. The HeartMath technology is for stress education and resilience training. It is not a medical device. We encourage you to consult a health professional before making any medical decisions. LEARN HOW TO: • Bring your heart, mind, and body into a calm, balanced state in the moment • Settle reactive emotions and manage everyday stress • Feel calmer, more centered, and more focused • Access clearer thinking to support better everyday decisions Just five minutes of coherence practice, three times a day, fits easily into your routine - and it’s enjoyable. Inner Balance guides you and tracks your progress as you shift your state and watch the changes occur in real time. FEATURES: • Real-time HRV coherence feedback to guide your practice • Guided meditations to support relaxation, focus, and a better wind-down before sleep • Real-time coaching tips with encouraging on-screen prompts • Advanced options: four challenge levels, customizable settings and screens • Access to a free cloud platform to save and review all your sessions and get tips and training WHAT REGULAR COHERENCE PRACTICE CAN SUPPORT: • A calmer way of handling everyday stress • More focus and mental clarity, even under pressure • Shifting more quickly into a state of calm and balance • Quieting the mind and letting go of racing thoughts • Strengthening inner resilience and recovering more quickly • Training coordination and reaction time for athletes • Complementing your own meditation practice Inner Balance Bluetooth sensor: clip the sensor to your earlobe and press the soft button on the sensor pod to activate a blue flashing light. Open the app and press the “Start” arrow to scan for the sensor. When your sensor ID appears and matches the number on the back of the pod, tap to accept and wait 15–20 seconds for calibration to begin your first session. Inner Balance Lightning sensor: follow the same steps to clip the sensor, open the app, and start your session. You can purchase an Inner Balance sensor at https://store.heartmath.com/innerbalance.
