## What is 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.

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. Cancel anytime in your Apple ID settings (Settings → Apple ID → Subscriptions). Account is charged for renewal within 24 hours prior to the end of the current period. Payment is charged to your Apple ID account at confirmation of purchase.

• New Drills Home screen for subscribers. One place to see what is unlocked and pick a drill to run.

• A larger set of practice drills and verification scenarios, covering more of the patterns that show up in real LLM use.

• Subscription state now updates immediately when you restore a purchase or redeem a code, with explicit feedback instead of silent success.

• Smaller refinements to the Paywall, Result, and Quiz screens to match the new flow.
