About

Saturdays Left

Read full description

You were born with roughly 4,000 Saturdays. Some are already gone. How many are left? Saturdays Left answers that question - personally, honestly, and with a purpose. Enter your birthday, walk through a quick health profile, and see your number. Not a generic statistic. Yours. Then watch it move. YOUR CHOICES COMPOUND Log your daily habits — exercise, diet, sleep, drinks, smoking — and watch your Saturday count rise or fall in real time. Good days add time. Hard days subtract it. Over weeks and months, the compound effect becomes impossible to ignore. PEOPLE YOU LOVE Add the people who matter most. See how many Saturdays you have left with Mom, Dad, your kids, your partner. Then see this: "If you see Mom once a month, you have about 221 dinners left together." That number changes how you spend your weekends. PLAN YOUR SATURDAYS A bucket list tied to your actual remaining time. Set dreams, assign target dates, and watch the runway between now and then. "You've completed 3 of 12 dreams. 1,847 Saturdays to go." SEE WHERE YOUR TIME GOES Enter your weekly screen time, commute, and overtime hours. Saturdays Left shows you how many of your remaining Saturdays those habits consume — and exactly how many you'd get back by cutting one hour a day. FAMILY TIMELINE A visual timeline showing when your kids leave home, when parents reach milestones, and where your lives overlap. The relationships that matter most, mapped against finite time. TRACK YOUR RITUALS Define the moments that matter — family dinner, date night, park with the kids, calling Mom. Track which ones happened each Saturday. See your completion rate and streaks. "You've had family dinner 34 of the last 52 Saturdays." SHARE YOUR NUMBER Generate a beautiful image of your Saturday count and share it. "I have 1,847 Saturdays left. What are you doing with yours?" PRIVATE BY DESIGN All data stays on your device. No accounts. No cloud. No tracking. No analytics. Your mortality is nobody else's business. Saturdays Left won't add a single day to your life. But it might change how you spend the ones you have.
