About

Memento V

Features
Read full description

Memento shows you your entire life on a single screen. Every small square is one week. The ones behind you are filled. The ones ahead are empty. That's it. That's the whole picture — your past, your present, and everything still to come, laid out in a grid you can hold in your hand. It sounds simple. It isn't. YOUR LIFE IN WEEKS Inspired by Tim Urban's "Your Life in Weeks," Memento translates one of the most powerful ideas about human time into a tool you can carry with you. Enter your date of birth and a life expectancy, and Memento builds your personal grid instantly — every week of your life, from the first to the last, accounted for. THE PEOPLE WHO MATTER MOST Time is not just about what you do — it's about who you're with. Add the people you love to Memento: a parent, a child, a best friend, a partner. Enter their age and how often you realistically see them each year. Memento calculates how many meetings you likely have left with that person. WHY IT CHANGES THINGS Reading that time is finite is one thing. Seeing it is another. When you look at your grid and count the squares you have left — really count them — something shifts. Priorities become clearer. Distractions feel lighter. The question "how do I want to spend my time?" stops being abstract. Memento is not a productivity app. It does not give you tasks, habits, or streaks. It gives you perspective. What you do with that perspective is entirely up to you. WHO YOU SPEND IT WITH Time is not just about what you do — it's about who you're with when you do it. Memento lets you attach people to periods of your life, so the grid reflects not just your timeline but the relationships that have shaped it. DESIGNED TO MAKE YOU FEEL SOMETHING Every design decision in Memento was made in service of one thing: emotional clarity. The grid is clean, quiet, and unhurried. There are no notifications pushing you to open the app. No streaks guilt-tripping you into engagement. You open it when you need to be reminded of something true, and then you close it and go live. FEATURES: Ā· Full life grid based on your date of birth and chosen life expectancy Ā· Filled and empty weeks shown at a glance Ā· Add notes and memories to any past week Ā· Mark meaningful people and relationships across your timeline Ā· Clean, distraction-free interface Ā· Private and local — no account, no cloud, no data collection Ā· Dark and light mode A NOTE ON PRIVACY Your birth date and life memories are deeply personal. Memento stores everything locally on your device. Nothing is sent to any server. No account is required. No data is collected. Ever. ON THE IDEA ITSELF Tim Urban's essay "Your Life in Weeks" has been read by millions of people because it does something rare — it makes an abstract truth feel real. Memento exists to extend that moment. Not as a morbid exercise, but as an honest one. You have a finite number of weeks. Most of them are genuinely yours to shape. That's not a reason for anxiety. It's a reason to pay attention. Open Memento. Count your weeks. Then go make them count.
