Huemoji

When did today start to get tense? And when did it ease off?

Hue reads the heart rate variability and heart rate your Apple Watch records, compares them with what's usual for you, and shows with a hand-drawn face whether your body is more tense or more relaxed right now. Glance at your wrist for the moment; open your iPhone to look back over the whole day.

SEE YOUR STRESS • Five hand-drawn faces, from relaxed to tense: your state at a glance • Drag the timeline to revisit any moment of the day • A small face for every day on the calendar, so you can see how your week went

UNDERSTAND YOUR RHYTHM • Focus Time, recorded automatically: how long your body stayed calm and steady enough to concentrate. Study, work or daydreaming, you decide what it was. • Focus Battery: full each morning, showing how much focus today has left. • Sleep: how long you slept last night, your sleep stages, and how regular your sleep has been. • Body clock: from your sleep and daytime activity, Hue estimates when you'll start getting sleepy tonight and when sleep will come most easily. • Recovery Time: how long your body usually takes to get back to normal after real strain.

ADJUST YOUR WAY Hue shows you the changes and leaves the conclusions to you. Once you can see your own rhythm, when to take a break and when to turn off the lights is up to you.

BEAUTIFUL AND PRIVATE • A hand-drawn design across iPhone, iPad, Apple Watch and widgets • One-time purchase. No subscription, no account • Everything is worked out on your devices; the app never sends your data to anyone • Available in English, Simplified Chinese and French

GOOD TO KNOW • Requires Apple Watch and permission to read the relevant data in Health. • Hue first learns what's usual for you, so your first face appears after about two weeks of wearing your watch. • Apple Watch Series 12 records more often; older models that meet the system requirements work too. • Results are for reference only. Hue is not intended for diagnosis or treatment and is no substitute for professional medical advice.
