What day of your life is today? LifeCounter is a journal with one question a day. As you answer, you slowly see more clearly the time you have with your parents and family, and what truly matters to you. Add your birthday, and it also counts which day of your life today is. ONE QUESTION A DAY A different question for every day of the year. Each one comes with a follow-up that asks why, like "What would you love to lose track of time doing today? Why does it draw you in?" so a one-word answer can grow into real reflection. You can also speak your answer with the keyboard's dictation. YOUR MOOD IN ONE TAP Happy, Calm, Okay, Tired, or Sad. Log how your day felt with a single tap, then look back on each month's moods and on what you wrote a year ago today. TIME WITH THE PEOPLE WHO MATTER Add your parents, family, or friends to see an estimate, based on averages, of the years you have together and how many more times you might meet. A small nudge to plan your next visit. BUCKET LIST Keep a one-line list of things you hope to do someday, and who you'd like to do them with. What you achieve stays on the list with the date. HOME SCREEN WIDGET See today's question and log your mood right from your home screen. Tap Write to jump straight to your answer. PRIVATE BY DESIGN Everything stays on your device. No servers, no ads, no tracking. Export your journal as text anytime. The number grows by one every day. We hope it helps you think about how to spend that day with the people you love.
