Most apps help you learn. Almost none help you not forget. Skill Decay Tracker shows each skill as a live health score (0–100%) that decays over time based on the Ebbinghaus forgetting curve. When a skill starts fading, AI generates a personalized 2-minute micro-challenge to bring it back. Works for any domain: coding, languages, music, academics. Built solo with Swift 6, SwiftUI, and 3 AI providers (Claude, GPT-4o, Gemini).
Hey Product Hunt! 👋 I'm Pavel, a solo iOS developer from Belarus.
6 months ago I realized I was forgetting technologies faster than I could learn them. I'd spend weeks on Core ML — then 3 months later couldn't remember the basic API.
So I built Skill Decay Tracker: an app that shows exactly which skills are fading and generates AI micro-challenges to keep them alive.
- Add any skill (coding, languages, music, academics)
- See its health score decay in real time (Ebbinghaus curve)
- Get 2-min AI challenges before it hits critical
Built with Swift 6, SwiftUI, SwiftData + Claude, GPT-4o, Gemini.
Free tier: 3 skills + 3 AI challenges/day — enough to feel the difference.
