About

Prokopton

Read full description

Prokopton delivers one Stoic quote to your phone each day — nothing more, and nothing less. The word prokopē (προκοπή) is ancient Greek for "progress." The Stoics used it to describe the ongoing, quiet work of becoming a better person. Not through grand gestures, but through small, daily acts of attention. That is what this app is. One notification. One thought. One day. THE QUOTES Over 400 hand-curated entries drawn from three foundational Stoic texts: - Meditations: Marcus Aurelius - Selected works: Seneca - Enchiridion: Epictetus Each quote is assigned to one of the three disciplines at the heart of Stoic practice: Desire, Action, and Assent. You can filter to whichever discipline you are working on, or receive quotes from all three. HOW IT WORKS Each day, within a time window you choose, a single notification arrives. The quote arrives in your notification — open the app for the full reading view, or simply read it on your lock screen. If you do open the app, you will find the quote displayed in a clean, typography-focused reading view. You can save favourites with a single tap. THE SHUFFLE Prokopton tracks which quotes you have already seen. You will work through the entire library before any quote repeats. The order is shuffled — no two users experience the same sequence. HOME SCREEN WIDGET A small and medium widget keeps the current quote visible on your Home Screen throughout the day, without opening the app. WHAT THIS APP DOES NOT DO No algorithm. No feed. No streaks. No gamification. No account required. No internet connection required — ever. No data leaves your device. No ads. --- "Don't explain your philosophy. Embody it." — Epictetus

Verdict

The call

The clearest difference is in-app purchases: Interactive Chess Books at none against Prokopton's 3. Interactive Chess Books also leads on iOS requirement (16.4 vs 18.0). Prokopton's advantage is update cadence (every 3 days vs every 4 months). On price, ads and device support there is nothing between them.
