Health Check-In Lab

Your personal health laboratory. Log how you feel in seconds, run experiments, build daily routines, and find patterns. Private. No account. All on your device.

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, run experiments, build time-blocked daily routines, and let the data reveal what works.

Health Check-In helps you identify the habits, routines, supplements, medications, and lifestyle factors that affect how you feel — then proves 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.

PRIVATE.

There are no accounts to create and nothing is in the Cloud. Your data is stored on your device and only leaves it when you decide to export it. AI queries only pass minimal data for analysis and nothing is stored.

QUICK DAILY CHECK-INS

Some apps require you to invest a lot of time inputting complex levels of information. Health Check-In keeps it fast and simple: Rate how you feel from 0–100%.

Optionally, create custom tags for positive and negative factors. Add notes — from a few words to detailed journal entries. Set up reminders to check in, or check in manually as often as you like.

Even the most thorough person needs less than a couple minutes a day, and each check-in can take as little as a few seconds. The goal is to make it easy enough to keep logging for months or years.

RUN PERSONAL HEALTH EXPERIMENTS

Start an experiment directly from a check-in. Choose from built-in templates or create your own. Test changes to supplements, medications, diet, exercise, sleep routines, or lifestyle habits. Schedule a follow-up reminder to evaluate results. Record outcomes and save successful findings as Key Results. Build a personal library of what works — and what doesn't. Instead of guesswork, systematically test one change at a time and learn from real-world results.

BUILD A DAILY ROUTINE

Create time-blocked routines for your day — Upon Waking, Morning, Afternoon, Evening, Before Bed. Add supplements, medications, and health actions to each block. Set reminders so you never miss a dose or habit. Create multiple routines and switch between them. Pro+AI subscribers can generate a personalized routine based on their health data, sleep patterns, and current supplements.

DISCOVER PATTERNS

View trends over 7, 30, 90, 180 days, or a full year. Compare check-in scores against sleep, activity, weather, air quality, and pollen data. Track medications, supplements, activities, symptoms, and health goals. Spot score swings with automatic change alerts. Save insights and lessons learned as Key Results.

CONNECT YOUR HEALTH TRACKER

Oura Ring, Fitbit, Apple Health, and Health Connect integration. Import sleep scores, sleep stages, deep sleep, REM sleep, HRV, resting heart rate, and daily step counts — all displayed on your Today screen without digging through menus. Overlay health data directly on your trend charts.

AI-POWERED HEALTH INSIGHTS

Get personalized analysis of your check-in history that identifies correlations between your habits and how you feel. Choose from preset analysis types — Key Insights, Correlations, Issue Summary, Sleep & Energy — or ask your own questions. Have multi-turn conversations, review past analyses, and export or share results. Ask AI to build you a complete daily routine based on your data. Richer and more detailed history provides even more thorough analysis — without sharing personal medical data.
