Enchiridion: MicroLearning App

Learn anything. Remember it for life.

Enchiridion is a subscription app built for people who want to keep what they learn. Auto-renewing subscriptions unlock the full catalog of learning paths, deep-dive articles, spaced-repetition study sessions, sync, and progress tools.

SCIENCE-BACKED LEARNING

Built on FSRS (Free Spaced Repetition Scheduler), Enchiridion schedules review right before you're likely to forget. The goal is long-term retention, not short-term cramming.

INCLUDED WITH SUBSCRIPTION

Your subscription unlocks: • Full access to structured learning paths • Deep-dive articles that explain the "why" behind the facts • Adaptive spaced-repetition study sessions • Progress tracking, streaks, and daily quests • iCloud sync across your devices

TOPICS YOU CAN STUDY

Explore practical and intellectual domains such as: • Personal Finance & Investing • Health & Longevity • Stoic Philosophy • Productivity & Focus • Relationships & Communication • Career & Business • And more

WHO IT'S FOR

• Lifelong learners building durable knowledge • Professionals expanding into new domains • Students who want better retention • Anyone tired of forgetting what they just learned

The name "Enchiridion" comes from the Greek word for handbook: a practical guide you carry with you. That's the goal here: a personal system for building useful knowledge that sticks.
