The LifeSigns app icon: a glowing fingerprint woven from threads of daily life

Coming soon to iPhone

The diary that writes itself.

LifeSigns quietly notices where you go, how you sleep, how you move, and how you feel — and turns it into the story of your days. It lives on your iPhone, and nowhere else.

LifeSigns Today screen for Wednesday, December 6, 2023: the day drawn as a colorful ring — 7.3 hours asleep, 5.7 hours socializing, a 58-minute walk, 40 minutes at the hair salon — over 5,666 steps.

Private like a paper diary.

Your life stays on your phone. Your health data, your places, your patterns — none of it is ever uploaded. There's no account to create, no cloud to trust, and no way for us to see your data — we couldn't peek if we wanted to. The only thing LifeSigns ever asks the internet for is the weather.

History

Scroll back to any day of your life.

Your iPhone has been quietly keeping records for years — steps, sleep, places. LifeSigns reads them the moment you install, and writes your past into a diary you can actually browse. Worn an Apple Watch for years? Your history is already there on day one.

Illustrative example

Places

It learns your places by name.

Not "location #47." The gym. Your coffee spot. Your parents' house. LifeSigns notices what you do where — the same café on weekday mornings becomes work, home after midnight becomes sleep. Guess wrong? Correct it once and it remembers. It even figures out your commute.

Heatmap

Every visit leaves a little heat.

Your daily orbit glows brightest. Old neighborhoods dim but never quite go dark. That one trip still burns as a small ember on the coast. Slide from this week to all time, and years of comings and goings light up a single map.

LifeSigns heatmap: ten years of visits glowing over a map of Chicago, brightest around one neighborhood, with green trails tracing the lakefront and daily routes.

Patterns

Insights you can actually trust.

LifeSigns looks for what genuinely moves your sleep, your energy, and your mood — then says it in plain English. When the evidence is strong, it tells you. When it's thin, it's labeled an early signal. And when there's nothing worth saying, it says nothing at all.

LifeSigns Insights feed listing real patterns — Sleep Debt Cascade, Optimal Workout Window, Weather Adaptation, Social Marathon Recovery — each carrying a Strong pattern or Consistent evidence badge.

Mornings

Start the day already in the know.

One quiet card with your morning coffee: how last night compares to your usual, whether today looks like a push day or a rest day, weather that might move your plans, and a memory from this day in another year.

Our one rule

The health app that tells you the truth.

Most health apps are built to keep you tapping — confetti for closing rings, streaks you're scared to break, a shiny new "insight" every morning whether or not it's real.

LifeSigns is built on one rule: never claim more than your data supports.

So it won't dress up a coincidence as a breakthrough. It tells you how sure it is, in plain words. And some days it simply says nothing new — because that's the truth.

It turns out an app you can believe is worth more than an app that flatters you.
