atrophy

Atrophy is a short diagnostic that measures how much of your judgment you've handed to LLMs.

It runs entirely offline. No accounts, no servers, no analytics, no third-party SDKs. Everything stays on your device.

WHAT IT DOES
- A focused calibration quiz: spot AI slop, verify weak claims, explain back what you read, gauge confidence.
- A calibration score with a plain-language reading of where you're solid and where you're drifting.
- A shareable result card you can save to Photos.

WHAT IT DOESN'T DO
- No tracking. No advertising IDs. No ATT prompt — there's nothing to track.
- No content rented from a server. The drills ship in the app.
- No social graph, no leaderboard, no streaks.
