Scar: Trading Journal · Finance · iPhone and Android

Turn your trading mistakes into lessons you actually review.

Log what went wrong in one plain sentence and Scar turns it into a flashcard: the mistake on the front, the lesson and the rule for next time on the back. Spaced repetition brings each lesson back, fast while it is fresh and less often once it has stuck.

What Scar does

One-line capture: Write it raw, the way you would say it out loud; review the polished card.
Spaced repetition: Fresh mistakes come back soon, learned ones fade into the background.
Grade by how it stings: Your grades set the schedule, so the deck adapts to you.
Your deck, your rules: Every card ends in a rule to follow next time.

Questions

Is Scar a P&L tracker?

No. It journals mistakes and lessons, not trades, and brings them back before you repeat them.

How does the review schedule work?

Spaced repetition: each card returns at a pace set by how much it still stings when you grade it.

Who is it for?

Any trader who has made the same mistake twice.
