Stop eyeballing trends in Apple Health. HONEST ABOUT RIGOR n=1 is for self-experimentation โ€” unblinded, uncontrolled, sample size of one. Results screens say so in plain language. The point isn't proof; it's a structured way to see whether the thing you're trying actually moves your numbers. THE CORE LOOP โ€ข Pick a curated protocol or design your own (intervention + duration + tracked metrics) โ€ข Log adherence and optional energy / sleep quality / mood scores in a 15-second daily check-in โ€ข HealthKit data is fetched on demand: sleep, HRV, resting heart rate, weight, VO2 max, glucose, body temperature, workouts โ€ข When the protocol ends, see a baseline-vs-protocol chart per metric with the % change called out PROTOCOL LIBRARY 12 curated experiments across sleep, circadian, cardiovascular, recovery, and lifestyle โ€” creatine, magnesium glycinate, Zone 2 cardio, morning sunlight, and more. Every protocol ships with a falsifiable hypothesis, an honest evidence summary, explicit cautions, and a difficulty rating. No fabricated effect sizes. SHARE A RESULT When a protocol ends, share a clean image card with the headline metric, supporting numbers, and a link back to the app โ€” for your group chat, journal, or wherever you log your experiments. PRIVATE BY DEFAULT n=1 works fully offline. Your HealthKit data stays on your device โ€” no ads, no analytics, no third-party tracking, no account required to start. n=1 is a self-experimentation tool, not medical advice. Always consult a qualified healthcare provider before starting any new health protocol.
