CORTEX - A 60-second morning reaction test with your own baseline (iPhone)

I'm the developer of CORTEX, a paid iPhone app built around a question: how does this morning compare with my usual mornings? If you just want to try a reaction-time test, a free browser test may be all you need. CORTEX is for making a short check-in part of a routine: take a 60-second test, build your own baseline, and experiment with one habit at a time. For example, you can compare your usual mornings with a period where you keep your phone away for the first hour. Results can be inconclusive. One better score isn't proof that a habit helped, and this isn't a medical or IQ test. The app includes trends and CSV export. Test history stays on your iPhone; no app account is needed. Pricing up front: paid access is required, with no free plan or free trial. US prices are $4.99/month, $34.99/year or $79.99 lifetime; local prices and eligibility for offers vary. App Store: apps.apple.com/app/apple-store/id6806795452 I'd value feedback on whether the listing makes the personal-baseline idea clear. If you choose to buy and complete your first morning test, I'd also like to hear what felt confusing. No need to share your scores or health data.
