About this app

Tick-tock! The clock is ticking, and spoiler alert: none of us make it out of here alive.

Meet Kisumori, the mindfulness app with a delightfully grim twist. Guided by Mortimer—a spectral cat with zero patience for doomscrolling—Kisumori helps you calculate your estimated lifespan, face your own mortality, and fill your remaining days with purpose, joy, and a little bit of chaotic fun.

Don't let your time slip away. Turn your mortality into your greatest motivation and make every single day count!

MEET MORTIMER, YOUR PHANTOM PURR-SUPREME
Mortimer is the ghost of a cat who acts as your ever-vigilant mascot and mortality guide. He requires daily check-ins and is always ready with a witty, morbid reminder to stop wasting your precious time on mindless screen habits.

BREAK DOWN YOUR ULTIMATE BUCKET LIST
Got big dreams, life goals, or promises you’ve made to yourself? Keep them all in your personal bucket list. If a goal feels overwhelming, ask Mortimer! He will deconstruct your biggest ambitions into actionable sub-tasks, complete with realistic timeline estimations and practical advice.

JOURNAL THE GOOD THINGS IN LIFE
Make "being alive" worth the trouble. Keep a daily gratitude journal designed to highlight life’s small victories. Whether it’s a soul-warming cup of tea at sunset, an unexpected hangout with old friends, or petting a friendly dog on your walk home—log the moments that make staying alive worthwhile.

BREAK THE ROUTINE WITH WILD QUESTS
Monotony makes life fly by in a blur. Mortimer cures the mundane cycle with silly, memorable Wild Quests! Step out of your comfort zone with fun micro-adventures: engage in a pillow fight with your spouse, visit a nearby train station you’ve never been to, or try a bizarre new dish. Create memories that stick!

LOCK YOUR PHONE & EMBARK ON FOCUS TIMERS
Reclaim your focus and live in the moment. Start a digital detox focus timer to lock away distracting apps while you work on Wild Quests, practice hobbies, cook, meditate, or simply rest. Calculate every minute spent off your phone doing things that truly enrich your life.

KEY FEATURES:

Lifespan & Mortality Counter: Keep your eye on the time you have left to spark meaningful daily action.
