Stress: HRV Monitor

Sleep, Recovery & Breathwork

Free · In‑App Purchases

That night, you woke up at 3am again. Your heart was racing. Your mind wouldn't slow down. Tomorrow's meeting kept replaying, and the harder you tried to sleep, the more awake you felt. The next day, you headed out with dark circles, reaching for coffee again and again. By afternoon your focus was gone. On the way home, you felt irritable for no reason. You thought you were just "tired." But tired from what? How tired? And how much longer can you keep this up? Your body has been sending signals all along. You just never learned to read them. Stress helps you understand what your body is saying. It quietly analyzes your heart rate variability, sleep patterns, resting heart rate, and daily activity, then compares them to your personal baseline to give you one simple answer: how are you doing today? No confusing jargon. No anxiety-inducing numbers. Just a stress score from 0 to 100, and four levels anyone can understand: Full of Energy · Feeling Good · A Bit Worn Out · Running on Empty What would you do when you see "A Bit Worn Out"? Maybe sleep an hour earlier tonight. Maybe take three deep breaths before your next meeting. Maybe trade the intense weekend workout for a quiet walk. Small changes, quietly adding up. Stressed? Breathe. Built-in breathing exercises help you relax anytime, anywhere. Follow the rhythm and let your body and mind settle. See your health trends at a glance. Intuitive charts reveal how your stress, heart rate, and sleep change—so you can spot your best days and when stress quietly creeps in. Daily summary, crystal clear. A concise status recap every day. No digging through charts to know how you're doing. Smart reminders, never pushy. When stress stays high, Stress gently nudges you: time for a break. Never intrusive—just a soft push when you need it. One night at 3am, you might wake up again. But this time, you open Stress and see your score: 72—A Bit Worn Out. No anxiety. No forcing yourself to sleep. You just take a few breaths and calmly close your eyes. The next morning, you realize you actually slept well. That's what Stress is all about.
