    Place the ring on your finger. A snug but comfortable fit ensures accurate measurements. It is recommended to wear it on your index or middle finger.

  • Connect the App

    Download QRing on iOS or Android, connect the ring via Bluetooth, and track your health and notifications directly in the app.

  • Monitor and Improve


    Check your data daily: sleep, energy levels, and recovery. Follow the recommendations to sleep better, reduce stress, and manage your activity efficiently.

Energy Score

Your energy score reflects how much vitality you’ve built throughout the day, taking into account factors like sleep, stress, recovery, and immune system health. A high score indicates you can handle intense physical or mental activities with minimal risk, while a low score signals the need to rest, avoid overexertion, and prioritize recovery.

Sleep Score

Your sleep cycles through light, deep, and REM stages, each supporting functions like tissue repair and memory consolidation. Circular automatically tracks these stages and creates your personal sleep profile, including cycle lengths, time to fall asleep, and how daily habits affect recovery. Beyond tracking duration, it provides personalized recommendations to help you wake up truly refreshed.

ECG + AFib Detection

Your heart rate is a key indicator of overall health. Circular monitors your heart rhythm and alerts you to any irregularities. Atrial fibrillation (AFib) is a common type of arrhythmia, marked by an irregular and often rapid heartbeat caused by chaotic electrical signals. If left untreated, irregular heart rhythms can harm the heart, brain, or other organs, and AFib may lead to stroke or heart failure. Early detection and management are essential for long-term health.

Stress Monitoring

Stress can disrupt your day, but Circular helps you track and quantify it in real time. Combined with personal notes and hourly predictions, it gives actionable insights to help you plan proactively, stay balanced, and maintain emotional well-being—like having a digital guide for a calmer, more productive life.

Breathing Sessions

Circular offers guided breathing sessions to help you find calm amid daily chaos. Simple exercises are designed to reduce stress, boost focus, or prepare you for sleep, and they adapt to your current stress levels and body’s needs—unlike generic meditation apps.
