What if time had a number that was uniquely yours? Stardate reimagines how you experience time by anchoring it to the most meaningful moment in your personal history: your birth. Enter your date of birth once, and the app calculates your personal stardate — a living number that reflects exactly where you are in your own journey through time. Your Personal Stardate Your stardate has three parts: the year of your life you're currently living, the day of that this year, and the percentage of today that has already passed. At 6:34pm on the 88th day of your 57th year, your stardate is 57088.77. It's a clock, a calendar, and a life odometer — all in one elegant number. More Than Just a Number Stardate also shows you how many days you've been alive, what percentage of your life this year represents, and what infinitesimally small slice of your entire life this single day accounts for. These aren't just statistics — they're perspective. The kind that makes you put down your phone and actually do something with your afternoon. Apple Watch Stardate includes a full Apple Watch app and complication so your personal time is always on your wrist. The complication displays the current percentage of your day — a quiet, constant reminder that time is moving. Stardate is for anyone who has ever felt that the conventional calendar is someone else's way of keeping score.
