NerveCenter is a simple symptom tracker built by a family living with chronic illness, for people seeking answers and patterns in the noise. When you’re working on self-improvement or dealing with chronic illness, dysautonomia, or other invisible conditions, it’s hard to remember what happened yesterday—let alone last week. NerveCenter gives you one calm place to log what matters and spot patterns over time. Log what actually affects your day: - Symptoms, flares and pain levels - Heart rate and blood pressure - Hydration and sodium intake - Triggers like overstimulation, exertion, sleep, stress and more - Free-text notes to capture anything your numbers miss Turn scattered moments into a story you can use: - Scroll through a clear history of your days, not a messy spreadsheet - See trends and “most reported” symptoms at a glance - Pull up past flares so appointments feel more focused and less stressful Optional AI-powered support (premium): - Ask an AI agent to summarize your recent logs in plain language - Get gently organized talking points for appointments - Explore possible patterns and questions to discuss with your care team The NerveCenter app does not provide medical advice and is not intended for diagnosis or treatment, or to replace medical care. Instead, it gives you structured information so you can think more clearly about your health and show up to appointments prepared. Whether you’re working on yourself or you're a caregiver trying to make sense of unpredictable symptoms, NerveCenter is designed to feel like a source of calm and control every day, not just on "bad days."
