Coherence App vs GENUS

Stop guessing recovery. Just breathe and observe your body improve through ITFD-guided breathing, HRV analysis, and clearer autonomic insight. Coherence is a structured physiological evaluation app built around Heart Rate Variability (HRV) and guided breathing sessions. It does not measure relaxation. It evaluates autonomic behavior, cardiac coherence and recovery patterns through structured session analysis. HOW SESSIONS WORK Sessions are started from Apple Watch. Breathing is guided using haptic feedback and color cues: • Haptic + blue = nasal inhalation • No haptic + green = nasal exhalation Inhalation timing is detected algorithmically in real time. The ITFD algorithm continuously evaluates HRV dynamics and determines the optimal breathing rate and inhalation–exhalation structure during the session. Signal acquisition is performed through Apple Watch. When available, external chest straps such as Movesense or Polar H10 can be used to refine HRV signal quality and improve algorithmic precision. If the HUM button is blinking before starting, the ITFD algorithm has detected that adding humming during exhalation is recommended. Humming is performed as Single-Breath Humming: a steady low sound during the entire exhale, producing stable nasal vibration. This vibratory nasal exhalation is associated with nitric oxide (NO) release. For more detailed information, see the corresponding sections in the Features area of our site. To avoid consciously forced diaphragmatic breathing, the app proposes a light index–thumb opposition as a sensorimotor anchor. This subtle gesture supports postural stability and reduces accessory respiratory engagement without deliberate control.

MEASUREMENT AND INTERPRETATION Each session generates an ITFD score derived from HRV behavior across repeated sessions. The model integrates SDNN and RMSSD dynamics to provide structured physiological interpretation. The main card displays, by default, the latest recorded session. If a specific day is selected in the calendar, the card reflects the results of that selected session instead. The dynamic background and main card interface include real-time graphical responses to physiological data during the session. Visual intensity and motion adapt continuously to coherence and stress dynamics, functioning as structured biofeedback rather than decorative animation. The main card includes: • A 7-day mini-chart showing daily minimum and maximum ITFD values • Directional change compared to the previous session • An interpretive phrase integrating structural analysis and circadian context • A selectable calendar • A 30-day trend summarizing overall progression The interpretive phrase reflects the session within the system’s daily pattern, not only an isolated change. In addition to the main interpretation, each session includes detailed charts displaying stress, coherence, and heart rate (HR) data. These charts provide structured visual feedback and allow observation of session dynamics both in real time and retrospectively. STRUCTURE The app is ideally designed for one session in the morning and one in the evening to evaluate daily autonomic patterning. Early sessions progressively stabilize as more data is recorded. Coherence does not provide generic stress scores, motivational framing, or lifestyle coaching. It is designed for users interested in structured HRV interpretation, cardiac coherence analysis, and measurable autonomic dynamics.

Make brain wellness a daily habit. GENUS brings light, sound, breathing and optional voice guidance into a simple daily practice. Choose GENUS 40Hz, Focus 10Hz, Calm 6Hz or Sleep 2Hz, then make room for a few quiet minutes. GUIDANCE AT YOUR PACE Listen to Mira or Rowan with gentle prompts and quiet gaps. Choose spoken guidance with text, spoken only, on-screen guidance, or no guidance. A CLEANER MEDITATION SPACE Adjust sound, haptics and visuals to suit your session. Dim the timer and controls until they disappear, then tap to bring the controls back. Pause, resume and mute voice guidance when you need to. BREATHE COMFORTABLY Follow your natural rhythm or use the free Without holds guide with equal inhale/exhale pacing from 3 to 6 seconds. Optional breathing sound cues support eyes-closed practice. Premium adds Coherent, Box, Triangle, 4-7-8 and Custom Box options. BUILD YOUR PRACTICE Review completed sessions and daily practice time. Start with the included session choices, Classic visuals, Pure Tone, Warm Drone and Rain. No app account is required. GENUS PREMIUM Unlock ad-free sessions, additional sounds and visual themes, custom 1–120-minute durations, advanced breathing patterns and an optional five-minute Sleep wind-down. SUBSCRIPTIONS Premium is available through optional auto-renewing subscriptions. Current prices, billing periods and any eligible trial are shown in the app and Apple's purchase sheet. Payment is charged to your Apple ID account. Subscriptions renew unless cancelled at least 24 hours before the current period ends. Manage or cancel in App Store account settings. Restore Purchases is available in Settings. IMPORTANT SAFETY INFORMATION GENUS uses flickering light. Do not use if you have epilepsy, a history of seizures, or sensitivity to flashing lights. Do not use while driving or operating machinery. Stop immediately if you experience dizziness, discomfort or visual disturbances. Consult your doctor before use if you have any neurological conditions. GENUS is a general wellness and relaxation tool, not a medical device. It is not intended to diagnose, treat, cure or prevent any disease.
