Life in weeks · for iPhone

Your life, week by week.

Your whole life drawn as a grid of weeks — and the end of the grid isn't a fixed number. It's a living estimate that moves as you live healthier.

Weeks lived This week Weeks ahead

Most apps show a static grid.
This one moves.

As your fitness, heart, sleep, and activity trends improve, weeks get added back to your grid. Let them slip, and you'll see that too — the clearest picture of how today's habits shape your time.

A horizon that updates every week

Start from a national life table for your age, sex, and country. Then adjust it with evidence-based factors from your 90-day Apple Health trends. Each week, see exactly which habit moved your horizon — and by how much.

Watch it move

Every week your grid recomputes. See which habit moved your horizon, and by how much.
