## What is Lumi?

Your body knows you're stressed before your brain admits it. Lumi listens.
Most people spend their days running on empty, wondering why they feel anxious, restless, or just off. Lumi uses your Apple Watch's HRV and Heart Rate data to show you exactly what's happening inside your body, so you can stop guessing and start feeling better.

#YOUR STRESS, FINALLY DECODED
Heart Rate Variability (HRV) is one of the most powerful indicators of stress in the human body. When it drops, your nervous system is under strain. Lumi reads that signal and translates it into clear stress levels, plain-English insights, and alerts before things spiral. No confusing charts. No raw numbers you have to Google. Just a clear picture of how you're doing, right on your wrist.

#SLEEP BETTER. RECOVER STRONGER.
Stress doesn't clock out when you do. Lumi tracks how well you slept and how recovered your body actually is when you wake up, so you know whether you're starting the day recharged or already running a deficit.

#ALERTS THAT ACTUALLY MATTER
When your stress climbs too high, Lumi sends you a gentle notification so you can take a breath, slow down, and take care of yourself in the moment. Whether you're grinding through a long work night, pushing through a draining social event, or your body is flagging something you haven't noticed yet, Lumi keeps watch so you don't have to.

#TRACK WHAT YOU DRINK. SEE WHAT IT DOES.
Coffee, tea, alcohol, energy drinks. What you put in your body directly impacts your stress and recovery, and most people never connect the dots. Lumi's Drink Library lets you log every drink that affects your day, then shows you how it's shaping your HRV, sleep, and energy over time. That afternoon espresso might be costing you more than you think.

#UNDERSTAND WHAT'S DRAINING YOUR ENERGY
Personalized Habit Insights show you how your daily choices shape your stress. Long-term trend views surface patterns across your HRV, daily score, and sleep over weeks and months. Full day-by-day history means you can always go back and understand what was going on.

#BREATHE YOUR WAY BACK TO CALM
Built-in Breathing Styles walk you through proven exercises with visual guides, helping you bring your nervous system back down in minutes.
