Cycle-aware training

Your workout should adapt to you.
Not the other way around.

Lune is the fitness app that works with your hormones, not against them.

Designed for female physiology. Not as an afterthought.

You’re not inconsistent. The programming is.

Most training programs still assume constant energy, linear progression, and a body that responds the same way every day. That's not how your body works.

The problem

Why does Tuesday’s workout feel twice as hard as last Tuesday’s?

That week you crushed PRs and the week you couldn't finish a warm-up? Not a motivation problem. Hormones, recovery, sleep, and life stage all change what your body can give you.

Generic apps treat every day the same. Lune is being built to adapt around recovery, changing energy, injuries, and cycle context instead of forcing the same plan every day.

Every fitness app treats me like a smaller man. I want one built for how my body actually works.
What women keep telling us
The Four Phases

Your cycle changes your training. Here’s how.

Estrogen rises, progesterone follows, energy shifts, recovery shifts. The four phases are a baseline — not a rigid rule — and Lune is built to train with that landscape instead of pretending it isn't there.

Menstrual phase
01

Menstrual

Days 1–5

Lower intensity, mobility, and light strength. Lune protects recovery so the month doesn't start in a hole.

Follicular phase
02

Follicular

Days 6–13

Your PR window. Heavier lifts, harder conditioning, new personal bests — while your body can actually absorb it.

Ovulatory phase
03

Ovulatory

Days 14–16

Your heaviest sessions often land here. Lune keeps this phase in view when shaping recommendations — without pretending every body responds the exact same way.

Luteal phase
04

Luteal

Days 17–28

Volume and endurance early, then Lune eases into active recovery as PMS symptoms set in.

Cycle doesn't look like this? Birth control, irregular cycles, PCOS, and perimenopause can change the picture. The four phases are a baseline — not a rigid rule.

Meet Luna
AI Coach

Meet Luna. A coach who feels like a friend.

Luna reads your cycle context, your recovery signals, and what you tell her. Then she adjusts the guidance like a coach who actually knows you — not a dashboard.

  • Knows your body better every day

    Luna keeps your cycle context, recovery signals, and what you tell her in view.

  • Explains your body in plain language

    “Why am I always tired in luteal?” You get a real answer — not a paywall.

  • Validates the hard days

    Didn't sleep. Bad knee. Off week. Tell Luna and get coaching that respects real life.

A conversation, not a dashboard

“Feeling tired today. Still do heavy legs?”

Totally valid. Today may be a better day to pull intensity back and train with recovery in mind.

Not a rigid plan. A coach you can talk to on the days your body has something to say.

Real Lune UI loop: today’s training context, synced to cycle and recovery.

The shift

Training that trains with you.

Not harder. Not softer. More honest. Your hormones are in charge — and your program finally knows it.

What Lune is not doing

Try Lune free.

No fake annual sale countdowns.

The founding offer is real. We're not copying the forever-sale playbook women already hate in other apps.

7-day trial. Real cancel button.

Lune is a paid subscription. The 7-day trial is the real thing — full app, no feature traps. Cancel from the app, not buried three menus deep.

Tell Luna what's actually going on.

Low energy, recovery, perimenopause. The point isn't to force you through a perfect plan — it's to make training feel realistic.

Your data is yours.

Cycle data, health data, and workouts stay yours. We don't sell data and we don't share it with advertisers.

Before you join

Things people ask before joining.

Does Lune work if I'm on hormonal birth control?

Yes — and it adapts differently. Hormonal birth control flattens the natural estrogen and progesterone curves, so Lune shifts to training around your energy, recovery, and symptom patterns instead of driving off cycle phase.

I have PCOS or an irregular cycle. Does this still help?

Yes. Lune doesn't assume a textbook 28-day cycle. If your cycles are long, short, irregular, or unpredictable, Lune uses cycle context alongside your logged energy, symptoms, and recovery.

How does Lune know what phase I'm in?

You can log your period inside Lune or import period history from Apple Health. Lune combines that cycle context with recovery signals like resting heart rate, HRV, and sleep to personalize your training guidance.

Is this based on real science?

Yes. We build on published research in menstrual cycle physiology and training adaptation. The literature is genuinely thinner than male-focused research, which is part of why Lune exists.

What does “50% off for life” actually mean?

The first 500 people who join through this waitlist get 50% off Lune — for as long as you stay subscribed. Not a first-year promo, not a teaser rate.

Is my health data private?

Yes. Your cycle data, health data, and workouts are yours. We don't sell data and we don't share it with advertisers.
