MARCUS

MARCUS is a daily Stoic practice app built on a simple premise: philosophy is something you do, not something you read. Most philosophy apps give you a quote and call it a day. MARCUS gives you a complete daily practice rooted in 2,000 years of Stoic tradition — morning intentions, structured lessons, guided exercises, and evening reflections that turn ancient wisdom into a living habit. FOUR PILLARS OF DAILY PRACTICE Today — Your Daily Anchor Each morning begins with a carefully chosen thought from Marcus Aurelius, Epictetus, Seneca and the wider Stoic tradition — 363 passages, a different one each day. Not a decorative quote — a lens for examining your day. Set your morning intention in under two minutes and return each evening for the Evening Review. On iPhone Duo, today’s thought and your journal sit side by side. Learn — Depth, Not Soundbites 78 structured lessons covering seven pillars of Stoic philosophy: Control, Acceptance, Virtue, Mortality, Calmness, Obstacles, and Time. Each lesson pairs primary source excerpts with modern commentary and a practical exercise. Guided journeys include "Stoicism for Exams", seven days on keeping a clear head through exam season, from the night before to results day; "Stoicism at Work", applying Epictetus, Marcus Aurelius, and Seneca to difficult colleagues, hard emails, and the pressure to let a job become your whole identity; "Friendship", on whom to trust and how to love; and "The Other Stoics", introducing Zeno, Panaetius, Hecato, Posidonius and Cato. Reflect — Your Private Journal Guided journaling with rotating Stoic prompts. Every entry is stored locally on your device and never leaves it. Review your reflections over time and watch your practice deepen. Practice — Active Exercises 25 text-guided Stoic exercises grounded in classical practices: negative visualisation, the view from above, evening self-examination, and more — plus a set of 60-90 second "Quick Resets" for the moment you actually need them, not just morning and evening. WORD FOR WORD FROM THE SOURCES Every quotation in MARCUS is taken word for word from a public-domain translation — George Long, Richard Mott Gummere, Aubrey Stewart, Thomas Wentworth Higginson and others — with only archaic forms like “thou” modernised. Settings › Sources & Translations credits every translator. DESIGNED FOR PRIVACY Your journal entries, reflections, and practice history never leave your device. No accounts, no cloud sync, no analytics, no tracking. No ads, no account, no tracking. Just a daily practice that respects your time, your attention, and your privacy.

Verdict
The clearest difference is in-app purchases: MARCUS at none against AI HD's 3. MARCUS also leads on update cadence (weekly vs every 3 weeks). AI HD's advantage is iOS requirement (12.0 vs 17.0). On price, ads and device support there is nothing between them.
