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. ATROPHY PRO (Optional Subscription) Unlocks the Practice Pack — additional drills for ongoing calibration. - Monthly: $4.99 / month - Annual: $49.99 / year Subscriptions auto-renew until canceled.
