Haily

AI Nutrition & Health Tracking

Recognize healthy habits and feel better.

Nutrition, sleep, and activity are the three most important modifiable levers for a healthy life and daily wellbeing. With simple voice-based input, Haily helps you track these levers every day and see how health, nutrition, activity, and sleep connect.

The first app that tells you what you need to know

Your devices already capture your heart rate, steps, sleep depth, and stress levels with remarkable precision. You have access to more physiological data than ever before.

Yet one essential thing is still missing: clear, personalized guidance.

You're shown numbers and trends, but not the "why" behind your good or bad days. You can see your metrics, but you don't get meaningful, personalized suggestions about what you should change to improve your well-being. Most apps track only one dimension—sleep or nutrition or activity—without revealing how these factors influence each other in your daily life.

You end up with accurate statistics, but very little clarity about which specific habits truly support your energy, mood, and long-term health.

A clear picture of your well-being

Haily transforms your meals, activities, sleep, supplements, and daily feelings into a coherent picture of your well-being. Instead of giving you generic advice or forcing goals, Haily observes how your body responds to your real habits and highlights what actually works for you.

Through natural language input and a holistic health model, Haily goes beyond tracking—it explains.
