The first AI daily planner that knows when YOU focus best. Men have hormonal cycles. Science has known this for decades โ€” 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 โ€” 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 โ€” 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 โ€” and learn to predict your peak performance windows. - SMART REMINDERS Phase-aware notifications that adapt to your real patterns. "Afternoon slump โ€” defer tough decisions." "Peak window open โ€” 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. Science-backed protocols, day by day. - MULTI-LANGUAGE Available in English, French, Spanish, Italian, German, Portuguese, and Dutch. Auto-detected from your device. - PRIVACY-FIRST Your data stays on your device by default. No ads. No data resale. GDPR compliant. Use the full app without signing up. WHY FLUX MATTERS Women have Flo, Clue, Natural Cycles. Men have nothing. Until now. We built Flux because men deserve the same precision tools to understand their bodies โ€” and use that understanding to perform at their best. PRICING Free: Daily log, vitality score, basic insights, 7-day history. Premium: Full action plan, weekly reports, smart reminders, challenges, NoFap analytics, unlimited history. $19.99/month or $119.99/year with a 7-day free trial.

Most men never find what actually works. They guess, they stack fixes, they wait for a doctor to say everything looks normal, and they're left exactly where they started. Owain is a daily sexual health tracker for men who want to understand what actually affects their performance, libido, and recovery, without guessing, without supplements, and without being told it's probably just stress. HOW IT WORKS Every morning, a 90-second check-in captures what matters: morning erection quality, libido, energy, mood, sleep, and stress. In the evening, an optional 30-second log captures sexual activity, alcohol, and substance use. That's it. Owain turns this into your Sexual Health Index, a transparent score built from three sub-scores: Sexual Function, Recovery, and Load. No AI in the calculation. No black box. You see exactly what drives your number. WHAT YOU GET - A structured program tailored to your goal (Last Longer, Perform Under Pressure, Morning Wood Protocol, Libido Reset, Baseline Optimizer, or Porn Reset) - Weekly observation reports that cite your actual data, not generic advice - An AI coach that references your logged patterns and suggests concrete experiments - 30 educational articles sourced exclusively from NHS, Mayo Clinic, CDC, and NIH - Apple Health integration for sleep, heart rate, and HRV - Trend charts across 7, 30, and 90 days - A 90-day tracking calendar showing your consistency WHAT WE DON'T DO Owain does not diagnose, treat, or prescribe. If your data suggests a pattern worth investigating, we say: "Consider discussing this with a doctor." We are a complement to medical care, never a replacement. Every insight is a descriptive observation of your own data. We don't invoke research to explain your personal patterns. We don't sell supplements. We don't connect you to telemedicine. We just show you what your body is telling you. PRIVACY Your data is yours. End-to-end encrypted. Never sold. Delete your account and everything goes with it. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://owain.app/privacy PRICING 7-day free trial. Then $44.99/year or $14.99/month. Cancel anytime from iOS Settings. --- Built for the men who'd never bring this up at dinner, but think about it more than they'd admit.
