Health Check-In: How I Feel

DISCOVER WHAT ACTUALLY MAKES YOU FEEL BETTER — without becoming a data scientist or health expert. Health Check-In is your personal health laboratory: log how you feel in seconds, see patterns on a color-coded calendar, run experiments, build daily routines, and let the data reveal what works. Built-in AI analyzes your data on demand without sharing sensitive information. NO ACCOUNTS TO CREATE AND YOUR DATA IS STORED LOCALLY - Health Check-In was built with privacy as a core requirement. You don't even need to give it your name. AI queries pass minimal data for analysis and nothing is stored. Identify the habits, routines, supplements, medications, and lifestyle factors that affect how you feel — then prove it with data. Whether you're dealing with fatigue, brain fog, digestive issues, insomnia, stress, chronic illness, or simply optimizing your health, Health Check-In gives you a practical way to connect the dots. QUICK DAILY CHECK-INS Rate how you feel from 0–100%. Add custom positive and negative tags — editable right from the check-in screen. Add notes, set reminders, or check in manually as often as you like. Each check-in takes as little as a few seconds. FLEXIBLE AND FORGIVING LOGGING Missed a day? Tap any past date in your History calendar to retroactively log symptoms, mood scores, or journal notes—ensuring a complete health picture without the stress of broken streaks. TRACK SUPPLEMENTS & MEDICATIONS Log what you're taking with dosage and notes. Free users can track up to 3 items; Pro unlocks unlimited. Your list appears on the Today screen alongside check-ins and health data. RUN PERSONAL HEALTH EXPERIMENTS Test changes to supplements, diet, exercise, sleep, or lifestyle habits. Choose from built-in templates or create your own. Schedule follow-up reminders, record outcomes, and save findings as Key Results. Build a personal library of what works — and what doesn't. BUILD A DAILY ROUTINE Create time-blocked routines — Upon Waking, Morning, Afternoon, Evening, Before Bed. Add supplements, medications, and health actions to each block with reminders.
