## What is FLUX?

Men have a cycle too. FLUX plans your day around it.

Your testosterone and your energy follow a daily rhythm: highest in the morning, a dip after lunch, a second wind later on. FLUX maps that rhythm to your own wake-up time, then puts each task on the hour that suits it.

HOW IT WORKS

1. Check in. Sixty seconds each morning: energy, mood, libido, sleep, stress and training, each from 1 to 10. You get your vitality score for the day.
2. Type your tasks. FLUX sorts them (deep work, strategy, creative, admin, training, social, recovery) and places each one on its best slot: hard thinking at your peak, admin in the dip, training when your body is ready.
3. Your day adapts. Slept badly? The check-in shifts your curve and re-plans the day: deep work moves later, a heavy session becomes a lighter one.

WHAT'S INSIDE

— Plan: your tasks on your best hours, as a list or a day agenda, re-planned after every check-in
— Check-in: six sliders, sixty seconds, one vitality score
— Cycle: your 24-hour energy curve set to your wake-up time, a 30-day view of your score, and the patterns behind your good and bad days
— AI Coach: up to 20 questions a day, answered from your own check-ins and plan. Why Mondays drain you, when to train, how to protect your peak. Coaching, not medical advice.
— Discipline (NoFap): streak counter, panic button with guided breathing, relapse journal that spots your risk hours, milestones from day 1 to day 90
— Training: a slot for your session with a suggested type: heavy, moderate, light or rest
— Apple Health (read only): sleep and HRV, plus resting heart rate, steps and workouts, sharpen your curve
— Calendar: FLUX reads your busy times so it never plans over a meeting, and writes your plan to its own Flux calendar. It never edits your other calendars.
— 8 languages: English, French, Spanish, Italian, German, Portuguese, Dutch and Japanese

FREE AND PREMIUM

Free: the daily check-in, your vitality score, a daily reminder, a preview of today's energy curve and the NoFap streak counter.
FLUX Premium unlocks the Plan and adaptive re-planning, Calendar, the AI Coach, Apple Health, Training, the full Discipline module and every insight.

SCIENCE, NOT BRO SCIENCE

The daily testosterone rhythm in men is well documented: levels peak in the early morning and fall through the day. Longer, monthly swings are reported in some men, not all, so the 30-day view shows your own trend rather than a fixed cycle. FLUX uses these rhythms as a planning guide and learns from your check-ins. It does not measure hormones.

YOUR PRIVACY

No account needed to start. Your data is never sold. Apple Health and Calendar access are optional and can be turned off at any time in iOS Settings, and you can delete your data from your profile.

NOT MEDICAL ADVICE

FLUX is a wellness and planning app. It does not diagnose, treat or prevent any condition and is not a substitute for professional medical advice. Talk to a doctor about any health concern.

SUBSCRIPTION

FLUX Premium is an auto-renewing monthly or yearly subscription. The yearly plan includes a 7-day free trial where offered. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within the 24 hours before that end.
