About this app
OneApp is your companion for everyday balance, recovery, and self-awareness. It brings together heart-rate-variability insights, voice-based check-ins, and personalized Bio-Tuning® frequency sessions in one calm, easy-to-use experience.
WHAT YOU CAN DO
• HRV Insights (Premium)
Track your heart rate variability over time. See daily trends, recovery guidance, and your personal history so you can understand how rest, stress, and routine affect your state.
• Voice Analysis (Premium)
Do a quick voice check-in to get a read on your energy and alignment, then pair it with sessions tailored to how you feel in the moment.
• Personalized Frequency Sessions
Guided Bio-Tuning® sessions matched to your current state — a simple way to reset, focus, or wind down as part of your daily rhythm.
• Always On Mode
Turn on a continuous background session and turn it off instantly whenever you like — full control, no waiting.
• Health-Aware
Connect your health data so your insights and recommendations reflect what's really going on with your body.
DESIGNED TO BE SIMPLE
