## What is Longview?

Apple Health shows your data one year at a time. Longview puts every year on one line.

Longview reads your Apple Health history — every year you've worn your Apple Watch — and draws each metric as one long line, week by week. See how your cardio fitness, resting heart rate, sleep and weight have changed since your very first record.

WHAT YOU SEE
• 8 metrics, full history: Cardio Fitness (VO2 max), Resting Heart Rate, Heart Rate Variability (HRV), Walking Heart Rate Average, Time Asleep, Daily Steps, Weight and Body Fat Percentage
• A thin line for each week's average and a thick line for the trend (±4 weeks), so the week-to-week noise and the long-term direction are drawn separately
• vs. a year ago: higher, lower or about the same — plus your all-time high and low
• Touch and drag any chart to see any week, all the way back to the start
• Gaps stay gaps: short ones are bridged, longer ones get a faint dotted line instead of a guess

YOUR DAY
All your history, layered by time of day:
• Sleep Stages — when you're usually in Deep, Core or REM sleep, or awake
• Exercise by Hour — when you usually work out, colored by workout type
• Steps by Hour — your average steps for each half hour of the day
• Daylight by Hour — when you're usually out in daylight

ZOOM AND SHARE
• Turn your iPhone sideways and pinch from 8 weeks out to every year
• Create images or animated videos of your charts
• Edit and copy a caption with a download link; save a separate download card
• Make a year-in-review from the metrics you can access

READ-ONLY, ON THIS IPHONE ONLY
• Longview only reads Apple Health. It never writes to it
• Everything is calculated and stored on your iPhone. No account, no server, nothing uploaded
• No ads, no analytics, no AI
• No scores, no verdicts — just your own numbers, drawn clearly
• No Apple Watch? Weight, steps and sleep from your iPhone, a smart scale or other apps are drawn too

Works with Apple Health. Longview doesn't give medical advice. If you feel unwell, talk to a doctor.
