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.

The body never lies. It has something to tell you. Shall we listen? Feelio is a daily practice of returning to yourself through the body. One minute a day, one question or one action that helps you hear what your body is trying to say. A woman's awakening happens through connection with the body, and this app is a beautiful first step toward yourself. This is not a health tracker or a mood journal. This is an app for women who want to live in contact with themselves: to feel, to notice, to understand their body and through it, their life. What's inside: 130 unique questions and actions, from simple ("Are you thirsty right now?") to deep ("What does your body want to tell you right now?"). About body needs, food, sleep, movement, sensations, emotions, sensuality, and the body-soul connection. A warm comment on every answer. Body journal: the history of all your answers. 8 awakening articles that unlock gradually. About dualities, feminine nature, and psychosomatics. Book an individual session directly from the app. Created by Zarina Tasbulatova, psychologist and psychosomatologist. Start listening. Your body is waiting. This app is completely free. No payment is required to access any features, content, or any functionality within the application.
