Life Timer is a simple yet thoughtful app that lets you experience both the time you have lived and the time you have left — from two perspectives: from your birthday, or from this very moment. Features • Enter your date of birth to automatically calculate your lived time and remaining time (The “end of life” date defaults to 100 years old and can be set up to 200 years.) • View elapsed and remaining time displayed visually in years, months, days, and hours • Switch between two modes: • Life Timer (from your birthday) • Re-Life Timer (from now) Compare how differently time “feels” through each mode with a visual progress bar • Write down things you want to do while you are alive (Ideal for those who want to reflect on milestones and set goals) • When you set your lifespan to 101 years or more, the app automatically shifts to a “Rose-Colored Life Mode” • Even after reaching your chosen end date, you can restart your timeline anytime — as many times as you want Recommended for • Anyone who wants to live each day more intentionally • Those who want to visualize the flow of time • People who want to reflect on milestones or remaining time • Anyone who feels ready to begin a new chapter today Notes • Life Timer is a tool designed to help you appreciate the time you have. • It does not include medical or fortune-telling features such as lifespan prediction. Device support and other details • This app is designed for iPhone only (not available for iPad or other devices) • No subscriptions, no ads, and no data collection Time is finite — but whether it feels long or short can change depending on your perspective. Life Timer was created as a small reminder to pause and reflect on that idea.
