SentNotes is your Daily Health Walletβa calmer, more intentional way to understand your wellbeing without fragmented apps or scattered inputs. It brings your health into one connected system where nutrition, behavior, and biology are not isolated data points, but parts of a single story about how you feel, function, and change over time. ONE WALLET. ALL YOUR HEALTH Everything is organized into four connected layers of understanding: Nutrition brings clarity to how food affects your body. You can see how certain meals influence your sleep, energy, or recovery, and understand patterns that build over time instead of isolated entries. Health Log connects symptoms, conditions, medications, prescriptions, and dosages into a continuous timeline. You can understand what triggered certain symptoms, or whether a treatment is actually improving how you feel, rather than relying on memory or guesswork. Activities show movement, workouts, and physical behavior in context. With optional location awareness, you can understand how different environments or routines influence your consistency and performance. Bio-Intelligence brings together deeper physiological signals like heart rate, sleep quality, recovery patterns, and reproductive health insights, so you can see how your body responds across stress, rest, and lifestyle. ALISON: YOUR AI ASSISTANT Alison helps translate everyday actions into meaning. A meal becomes a breakdown of nutritional impact. A symptom becomes part of a larger pattern. A question becomes a connection between habits and outcomes. Over time, it helps you understand not just what is happening, but what is influencing it. BIO-INTELLIGENCE, SIMPLIFIED SentNotes connects with Apple Health to unify steps, heart rate, sleep, and calories into one coherent view. It can also measure heart rate directly using your camera, turning everyday moments into signals you can actually interpret. Instead of isolated metrics, you see how your body behaves over timeβhow sleep affects recovery, how stress affects heart rate, and how routines shape your baseline. BUILD CONSISTENCY Progress is built through repetition, not intensity. SentNotes introduces Credits for healthy actions, streaks for continuity, and challenges that reinforce consistency. Shared progress with buddies adds gentle accountability without pressure. DESIGNED FOR DAILY USE Everything is built around a card-based system that keeps information structured but lightweight. The interface adapts to your habits, helping you stay focused on what matters without overwhelming you with dashboards or tabs. STOP TRACKING. START UNDERSTANDING. Your health becomes meaningful when connections are visible. SentNotes brings everything together into a single system designed to help you understand what affects you, what changes you, and what helps you improve. SentNotes is a wellness tool and not intended for medical diagnosis or treatment.
