## What is Scar?

Scar turns your trading mistakes into a deck you actually review.

Every trader knows the feeling: you make the same mistake twice. Scar exists to break that loop. Log what went wrong in one plain sentence, the way you'd say it out loud, and Scar shapes it into a clean flashcard: the mistake on the front, the lesson and the rule to follow next time on the back.

Then it does the part discipline usually skips: it brings the lesson back. Scar uses spaced repetition, so a mistake you just made resurfaces fast, and one you've internalized fades into the background. Grade each card by how much it still stings, and the schedule adapts to you.

- One-line capture: write it raw, review the polished card
- Spaced-repetition review tuned for behavior, not trivia
- Tags to surface your patterns: revenge trades, no stop, oversizing
- Private by default, synced across your devices

Scar is not a charting app and not a broker. It is the journal that makes your worst trades teach you something.

Scar Premium is an optional auto-renewable subscription (monthly or annual) that adds cloud sync and AI polish. Payment is charged to your Apple ID at confirmation; it renews automatically unless canceled at least 24 hours before the end of the current period, and you can manage or cancel it in your App Store account settings.
