Description by Kosei Sakaguchi Written by the developer, not by AppBrain. Click to read.
Last Line is a memento mori app that counts down your remaining days — and asks you to write just one line each day.

No journal. No diary. Just one line. As if today were your last.

HOW IT WORKS
• Enter your birth date. The app calculates your remaining days based on actuarial life expectancy data.
• Every day, you receive a philosophical question — drawn from Stoicism, Zen Buddhism, and Existentialism.
• Write one line. That's it. One line per day.
1,000 QUESTIONS
From Marcus Aurelius to Kierkegaard. From Zen koans to Camus. Each question is designed to cut through noise and reach what matters.

"If this were your last morning, what would you leave unsaid?"
"What are you pretending not to know?"
"Who would you call if you had one hour left?"

YOUR COUNTDOWN
A simple number. The estimated days you have left. It doesn't lie. It doesn't comfort. It just counts.

FAMOUS LAST WORDS
The app opens with real deathbed quotes from Steve Jobs, Oscar Wilde, Beethoven, and others. Their last words. Soon, yours.

FEATURES
• Death countdown based on life expectancy data
• 1,000+ unique daily questions from philosophy and contemplative traditions
• One-line daily entry — minimal, intentional
• Staggered fade-in animations and haptic feedback
• Pure black UI — no distractions
• All data stored locally on your device

LAST LINE PRO
• Life prediction based on personal habits (smoking, exercise, sleep, stress)
• Expanded question library
• Home screen widget

Built for people who find meaning in brevity, darkness, and honesty.

Your days are numbered. Make each line count.
