Mori makes time visible. A minimalist life calendar shows the weeks of your life — compact, calm, and distraction-free. Inspired by memento mori: when you see time’s finitude, you may make clearer choices. How Mori helps • Life calendar See your life as a quiet grid of weeks. Each dot represents one week. • Current week Focus on the present week, reflect on it, and add a short private note. • Weekly reflections Mark meaningful weeks, add a mood, and write down what mattered. • Month view Navigate your weeks more easily through a month-based view. Tap any week to reflect on it. • Life events Add meaningful moments with a title, date, color, category, symbol, and optional note. • Life phases Mark longer chapters of your life, such as school, relationships, work, places, or personal seasons. • Review Look back at what happened since your last birthday: events, reflections, and meaningful weeks. • What-if mode Explore temporary scenarios without changing your profile. • All Weeks A simple view where every week counts the same. • Good Weeks An optional quality-weighted view where later years can be subtly adjusted and marked. • Personalizable Set your date of birth and sex, with optional simple inputs such as smoking, exercise, alcohol, height, weight, sleep, stress, screen time, steps, diet, social contact, and chronic conditions. • Fine-tuning Choose when good years start to decline and the quality toward life’s end. • At a glance Optionally show remaining weeks at the top. • Widgets Small, medium, and accessory widgets show your remaining weeks, progress, and important markers such as events and life phases. • Display options Show or hide age markers, life events, and life phases. • Appearance Light, Dark, or System. • Private by default No account. Your data stays on your device unless you enable optional iCloud backup. Important Mori is a visualization and an approximation. It is not health or life advice and does not replace medical judgment.

PepStack – Stacks, Vitals, Blood & Training Plan your stack. Track your progress. See what actually works. PepStack is built for people who take their supplements seriously — and want to see how their stack relates to their body, blood and performance. Instead of five apps and a spreadsheet, it’s all in one place, neatly connected and fully private. Four areas, one picture: Stacks Build custom supplement stacks: compound, amount, dosage, schedule and phases — exactly how you run them. A visual plan shows what’s due when, and reminders make sure you never miss a dose. Vitals Connect Apple Health or Health Connect to pull in steps, sleep, resting heart rate, HRV and more automatically — or log your own metrics by hand. See how your routine shows up in daily life. Blood Log your blood tests — manually or via photo/PDF scan — and keep 100+ markers in view. With a plain-language marker wiki, personal reference ranges, trend charts and a side-by-side comparison of two tests (improved / worse / stable). Training Log your workouts, sets and progress and close the loop: stack, recovery and performance in one app. Everything in context The real value isn’t single numbers — it’s the full picture. Watch how your stack, vitals, blood markers and training move together over time, and make better decisions for yourself. Private by design Sensitive data is end-to-end encrypted — only you have access. Secure cloud backup & sync across your devices. No data sales. Your data is yours. Full stop. Who’s it for? Biohackers, athletes, self-optimizers and anyone ready to move their supplement routine from sticky notes to a clean, data-driven system. Stop guessing. Start tracking. Get PepStack.
