LifeTrends

About

Your life has patterns. LifeTrends finds them. Designed by a Yale biophysicist, LifeTrends applies real data science to the numbers your iPhone already has — steps, sleep, heart rate, weight, and a dozen more, plus the places in your photos — and turns your entire Health history into plain-English trends: • You walk more on weekends • You sleep less on Sunday nights • You climb more stairs in June (a broken elevator, perhaps?) • Your resting heart rate rises with your weight • You walk more when you visit New York • You lose weight during summer • You sleep more after visiting Paris (resting from all the walking?) • You slept less and earlier after New York (jet lag?) • Your blood pressure is lower on your most active days • You walk the most around 6 PM Tap any trend to open it into a full-size chart, with a gentle haptic tap. And at the bottom of the Summary tab, your record days: the day you walked the most, covered the most distance, and slept the longest — each tagged with where in the world you were, straight from your photos. REAL STATISTICS, NOT HOROSCOPES LifeTrends was built by a working scientist, and it works like research: fit a model on your device with Apple's machine-learning tools, test whether the effect is real, never overclaim. A difference only becomes a trend when it is big enough to matter and consistent enough that it isn't luck — one unusual week stays an unusual week. The Info tab shows exactly how every conclusion is reached. NOTHING EVER LEAVES YOUR IPHONE No account, no server, no analytics. Every number is read, analyzed, and displayed on your device. Even the "where were you" part is private: the app reads only the date and location details of your photos — never the pictures — and matches them against a city list built into the app, so not even a map lookup goes online. SEASONS, RHYTHMS, AND AFTER-EFFECTS Because LifeTrends reads your entire history, it sees the slow rhythms too: whether you sleep longer in winter, how your weight drifts across a season, the time of day you move the most — and what changes after events, including how crossing time zones shifts your sleep. Come back from across the world and it may notice you sleeping shorter and earlier, and ask whether it's jet lag. FOUR SIMPLE TABS • Summary — your strongest trends, your daily rhythm, and your record days. • Statistics (Pro) — every variable you measure, charted over your whole history: tap any chart to set an exact date range and re-bin by week, month, or year. Plus correlation scatter plots that link your variables, shown only when the relationship passes the significance test. • Info — a plain-language look at how the app finds patterns. • Settings — pick your home city yourself (it even fixes your hemisphere so seasons read correctly), and switch the app's access to any variable off — LifeTrends then simply stops reading it. LIFETRENDS PRO The core experience is free: the Summary tab analyzes your last 2 years and keeps working forever. A single one-time purchase — no subscription — unlocks the Statistics tab and analysis beyond 2 years, where the deepest seasonal and long-term patterns live. WHAT YOU'LL NEED Step, distance, stair, and location trends work with just your iPhone. Heart, sleep, exercise, and daylight trends come from a wearable such as Apple Watch; blood pressure needs a connected monitor, and calorie or weight trends need meals and weigh-ins logged to Health. LifeTrends analyzes whatever you have and quietly skips the rest. Both permissions are read-only, and photo access is optional. LifeTrends is for reflection, not diagnosis. It shows patterns in your own recorded data and is not a medical device.
