## What is Skill Decay Tracker?

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.

TRACK YOUR PROGRESS
— Activity heatmap across the last 12 weeks
— XP and leveling system that rewards consistency
— Per-skill accuracy and session history
— Challenge type breakdown to spot patterns
— Daily streaks to build a habit

STAY ON TOP OF IT
— Home screen widgets show your most at-risk skills at a glance
— Daily reminder notifications at a time that works for you
— Critical decay alerts when a skill drops below the danger threshold

BUILT FOR DEPTH
Skills are organized by category — Programming, Language, Tool, Concept, or Custom. You control the decay rate and question count for each skill. Everything syncs across your devices via iCloud.

PRO
Unlock unlimited skills, higher question counts per session, and full analytics. Or use your own API key to get Pro-equivalent access without a subscription.

Available in English and Russian.
