Skill Decay Tracker uses the Ebbinghaus forgetting curve to show you exactly when your knowledge is fading — and stops it before it's gone. Add any skill you want to retain: a programming language, a spoken language, a framework, a concept, or anything custom. The app tracks how your memory decays over time and tells you which skills need attention today. PRACTICE WITH AI Each session generates fresh challenges tailored to your skill — multiple choice, true/false, and open-ended questions. Connect your own Claude, OpenAI, or Gemini API key for unlimited sessions, or use the built-in quota. KNOW YOUR WEAK SPOTS The health score for each skill updates in real time based on how long it's been since you last practiced and how well you did. Red means it's fading fast. Green means you're solid.
