Flux vs n=1

The first AI daily planner that knows when YOU focus best. Men have hormonal cycles. Science has known this for decades — but no one talks about it. Your testosterone follows a 24-hour circadian rhythm: it peaks in the early morning and drops by up to 43% by evening. This affects everything — your energy, mood, focus, motivation, libido, and physical performance. Every single day. Flux is the first app built specifically for men to track these rhythms and plan their day around them. - DAILY VITALITY SCORE Track 6 dimensions in 60 seconds: energy, mood, libido, sleep, stress, training. Get an instant score (0-100) and see how your day compares to your baseline. - AI DAILY ACTION PLAN Get personalized recommendations on when to focus, train, take decisions, or rest — aligned with your hormonal peaks and dips. Stop fighting your biology. Work with it. - HORMONAL CYCLE INSIGHTS Visualize your 24-hour testosterone curve and your monthly infradian rhythm. See patterns most men never notice — and learn to predict your peak performance windows. - SMART REMINDERS Phase-aware notifications that adapt to your real patterns. "Afternoon slump — defer tough decisions." "Peak window open — tackle deep work now." Up to 7 reminders per day, all contextual. - NOFAP ANALYTICS (PREMIUM) Track your streaks, correlate abstinence with energy/mood/focus, and see your own data on classic milestones (day 7, 14, 30, 90). - WEEKLY PERFORMANCE REPORTS Every Monday, get a recap of your previous week plus 3 targeted actions to improve. Premium only. - GUIDED CHALLENGES (PREMIUM) 7-Day Sleep Reset. 14-Day Energy Boost. 30-Day Peak Performance.

Stop eyeballing trends in Apple Health. HONEST ABOUT RIGOR n=1 is for self-experimentation — 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 • Pick a curated protocol or design your own (intervention + duration + tracked metrics) • Log adherence and optional energy / sleep quality / mood scores in a 15-second daily check-in • HealthKit data is fetched on demand: sleep, HRV, resting heart rate, weight, VO2 max, glucose, body temperature, workouts • 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 — 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 — 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 — 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.
