Day Left — Life Countdown

Every morning you wake up, one day fewer remains. See your life in numbers — cut the waste, build better habits, and make every day count.

WHAT IF YOU COULD SEE YOUR LIFE RUNNING OUT — IN REAL TIME?

Day Left shows you exactly how many days you have remaining, based on your birthday and life expectancy. Not to scare you. To wake you up.

Most of us live like we have unlimited time. We scroll for hours. We procrastinate. We let weeks blur into years. Day Left puts a real number to that cost — and shows you a clear path forward.

HOME — YOUR DAYS REMAINING

One bold number. Your days left, updating in real time. A progress bar showing exactly how far through your life you are. Every time you open this app, it's one fewer day. Let that sink in.

STATS — THE COST OF WASTED TIME

Enter your daily screen time by app — Instagram, TikTok, YouTube, Chrome, Games. Day Left calculates how many total days of your life you have already burned on screens. The number will shock you.

PROJECTION — YOUR FUTURE, TWO WAYS

A graph showing two versions of your future: one if you carry on as you are, and one if you cut the waste and build healthier habits. The gap between those two lines is time you can still take back.

HABITS — ADD YEARS BACK TO YOUR LIFE

Toggle on Exercise, Healthy Diet, Quality Sleep, and Mindfulness. Each habit adds estimated days back to your projection — based on published health research. See the compounding effect of small changes.

SETTINGS — FULLY PERSONALISED

Set your birthday, life expectancy, daily screen usage per app, reduction targets, and notification time. The app is fully bilingual — English and Tieng Viet.

DAILY MIDNIGHT REMINDER

Enable the daily notification and Day Left will remind you at midnight: you lost another day. Use it as a quiet prompt to reflect — was today worth it?

YOUR DATA STAYS ON YOUR PHONE

No account. No sign-up. No cloud sync. No tracking. Everything is stored locally on your device. Day Left works completely offline.
