Fill your own 100 years, one day at a time.

100 Years is a life-tracking app that visualizes your lifetime based on your date of birth, helping you build meaningful habits and achieve weekly goals through consistent daily records.

■ 100-Year Life Calendar

View your entire life as a calendar of 1,200 months. See how much of your journey you've completed, where you are today, and the time that still lies ahead—all in one intuitive view.

■ Daily Stamps

Track the habits you want to maintain, such as exercising, studying, reading, or anything else that matters to you.

Review your progress through monthly calendars, statistics, and consecutive-day streaks.

■ Weekly Goals

Set one meaningful goal each week and mark it as completed when you achieve it.

Completed goals are crossed off automatically, while your past goals are saved so you can look back on your progress over time.

■ Achievements

Collect trophies based on your age, habit records, weekly goals, and the time you've spent using the app.

Celebrate the small milestones that become meaningful achievements throughout your journey.

■ Home Screen Widgets

Check your progress without opening the app.

See which day of your life you're on and how much of your 100-year journey has passed directly from your home screen.

Customize widget backgrounds and transparency to match your style.

■ Personalize Your Experience

Create a look that's uniquely yours with a variety of themes, calendar styles, and fonts.

Some premium themes and calendar styles are available through rewarded ads or in-app purchases.

■ Secure Backup

Start instantly with an anonymous account, or connect your Google account to sync and back up your data across devices.

If you're using an anonymous account, your data is stored only on your current device. To keep your records safe when changing devices or reinstalling the app, we recommend linking your Google account.

Every small record becomes part of your story.
