Core helps you build your inner strength with the most immersive meditation experience out there. This is meditation you can feel, guided by dynamic vibrations, audio and lighting. Connect your Core Meditation Trainer with the app, drop in, and go. Together with the Trainer, the Core app will track your personal progress using stress-level measurements and other biometric data insights. DIVE INTO OUR MEDITATION LIBRARY - Learn new Breath Training techniques, then practice them on your own with Core's guiding vibrations. - Unwind with longer guided classes, or jump into a short 3-minute session — whatever fits your schedule. - Meditations guided by our expert instructors cover a variety of topics, geared towards all experience levels. - Pick a vibration pattern, choose a duration, and drop into one of Core's original ambient and musical soundscapes. Your Core Meditation Trainer pulses alongside your sessions. Depending on the type of meditation, the vibrations will guide you in learning Breath Training techniques, or serve as a gentle reminder to help focus your attention and anchor you in the present. MEASURE YOUR PROGRESS No more wondering whether meditation is actually working for you or not. With the Core Meditation Trainer connected to your app, you can see how meditation is directly affecting your body through several different metrics: - Training - Track your consistency over time. Making meditation a part of your regular routine helps train your brain to respond to it, and unlocks numerous health benefits. - Calm - Calm is represented by the dominance of your parasympathetic nervous system. We measure this based on your heart rate and its variability over time (HRV). With practice, you can train yourself to reach a Calm state more quickly. - Focus - Some techniques get you energized, priming your mind and activating your senses into a highly responsive state. Core measures how much time you spend in a Focused state by the pattern of your heart rhythm. After each meditation, Core will show you how Calm and Focused you were. Long-term historical graphs lets you see how your resilience to stress is changing over time, and track your progress with daily streaks. Core will also integrate with Apple HealthKit to share Mindful Minutes and read data to improve the accuracy of your biometric insights.

Are you feeling stressed, burned out, or just not yourself? Optimal HRV is the guided biofeedback app that teaches your body to calm down — for real. Backed by a Harvard Medical School mindfulness expert and trusted by athletes worldwide. Optimal HRV pairs real HRV data with live biofeedback, so every session trains your nervous system to handle stress better — not just tells you that you're stressed. Why HRV and Biofeedback Training Work Your Heart Rate Variability (HRV) is a window into how well your body handles stress, anxiety, and recovery — and biofeedback is how you train it to improve. Together, they show you what's happening inside your body, then guide you to change it in real time. With Optimal HRV, you can: • See how stressed — or relaxed — your body really is, using real HRV data. • Learn what actually helps you recover, from sleep to workouts to busy workdays. • Use live biofeedback to train your body to relax faster, right as it's happening. • Discover your own personal "perfect breathing rhythm" through guided sessions. Features You'll Actually Use • Daily Check-Ins — take a quick reading each morning, or anytime you want to see how you're doing. • Your Perfect Breathing Rhythm — a simple test finds the exact breathing pace that works best for you. • Live Feedback While You Train — a simple on-screen guide shows you when you're doing it just right. • Calming Mindfulness Sessions — guided practices created with a Harvard Medical School mindfulness expert, covering stress, anxiety, pain management, athletic performance, and more, with calming narrations in your choice of voice. • Easy-to-Read Progress — see your trends over days, weeks, and months, no data expertise needed. • Video Tutorials — learn HRV concepts and techniques at your own pace. • Make It Yours — adjust sounds, pacing, and reminders so training fits your life. • Available in 14 Languages — use Optimal HRV in your native language. • Device Testing — quickly verify if your heart rate monitor works with the app. • Great for Teams Too — employers and coaches can track group wellness together (Dashboard access needed). Why Optimal HRV Works with External Sensors (Not Apple Watch) We choose precision over convenience. Apple Watch is great for daily wellness, but Optimal HRV is built for serious HRV training. That's why we connect directly to an HRV monitor via Bluetooth — they deliver millisecond-accurate R‑R intervals that wrist sensors can't match. What that means for you: • More accurate data – better insights, better decisions. • Real-time streaming – no gaps, no guesswork. • Reliable results – trusted by athletes and coaches worldwide.
