About Seize Week
Your whole life, drawn as a grid of weeks. The weeks you've lived are filled in; the weeks ahead are waiting. The end of the grid is not a fixed number. It is a live estimate that responds to your Apple Health trends, built to be illustrative rather than predictive. Most "life in weeks" apps show the same static grid to everyone. Seize Week 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. It is a clear way to see how today's habits move the estimate. HOW IT WORKS • Start from a national life table for your age, sex, and country. • Adjust it with evidence-based factors from your 90-day Apple Health trends — VO2 max, resting heart rate, daily steps, sleep duration, exercise minutes, body measurements, and blood pressure — plus a couple of things Health can't measure, like smoking and alcohol. • Every adjustment shows its source. Tap any factor to see the research behind it and how your own trend is moving. • Each week, your horizon updates. See exactly which habit moved it, and by how much. PRIVATE BY DESIGN • No account. No sign-up. No servers. • Your health data is read-only and never leaves your device. Only your estimate history syncs, through your own private iCloud. • Free with ads (CloudX); a one-time Remove Ads purchase turns them off. Your Health data is never used to target them. AN HONEST ESTIMATE Seize Week is a motivational visualization, not a medical prediction or health advice. Nobody knows your number. What this app shows is how your choices move the odds — and how much of your life is still ahead of you. Carpe septimanam. Seize the week.
What’s new
Version 1.3.3 · Updated October 7, 2026
Remove Ads is now one tap away: a new button at the top of the home screen, next to Settings. It shows the price and lets you buy or restore. The purchase is also now on sale in every country where Seize Week is. Your check-in now shows on the right week. Tap this week on the grid and the focus and target you set are there, instead of "No check-in recorded". The entry was always saved — it was being drawn on the block next door. The "your horizon moved" notification now arrives in your language, and counts weeks the way your language counts them.
