About

Stoic

Features
Read full description

Some minds don't stop. You replay the conversation, rehearse the argument, and carry a worry that isn't yours to carry. Stoic Control Journal is a calm place to put it down. Built on one Stoic idea โ€” the dichotomy of control โ€” the app guides you through four short steps: 1. Write the worry, exactly as it sits in your head. 2. Sort it: what here can I actually influence, and what can't I? 3. Name one next action โ€” small and concrete. 4. Close calmly, and set the rest down. No streaks to guilt you. No feed. No noise. Just a quiet, repeatable practice for overthinking, pressure, and letting go. What's inside: - A guided control-journal entry based on Marcus Aurelius' and Epictetus' practice of separating event from response - A short daily Stoic prompt, generated on your device - An optional wellness tab that can summarize Apple Health categories you permit (read-only), with a transparent daily score - Everything stored privately on your device โ€” no account, no ads, no tracking, no cloud upload Stoic Control Journal is for general reflection and calm. It is not medical advice and does not diagnose, treat, or predict any condition. Write the worry. Find your next step.
