Your morning, synced

This is what Lune looks like.

Open the app and see where you are in your cycle, how your energy is likely to trend today, and a workout that actually makes sense for your body right now.

The Problem

You're not inconsistent. The programming is.

♂

Designed for female physiology. Not as an afterthought.

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.

⚡

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.

🔄

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

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.

What women are actually saying

“Every fitness app treats me like a smaller man. I want one built for how my body actually works.”

Your plan bends with real life

Miss a workout. Need a lower-intensity day. Tell Luna what's going on and get guidance that respects real life without treating one off day like failure.

Tell Luna what your body needs

Bad knee. Didn't sleep. Coming back from an injury. Tell Luna and get coaching that takes your context into account instead of pretending every day feels the same.

Built for changing hormones and life stages

Your body changes — your training context should too. Cycle shifts, hormonal birth control, postpartum and breastfeeding, and perimenopause shouldn't be afterthoughts.

The Four Phases

Your cycle changes your training. Here's how.

01

Menstrual · Days 1–5

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

02

Follicular · Days 6–13

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

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.

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.

Luna
Day 10 · Follicular

Morning, Sofia. Day 10 — follicular. Energy should be climbing. 💪

Feeling tired today though. Still do heavy legs?

Thinking…

Totally valid. Swap to moderate intensity — glutes & hamstrings instead of heavy squats. Your body will thank you tomorrow.

Why am I always tired in luteal?

Thinking…

Progesterone peaks then — it raises your basal temp and increases fatigue. Not weakness, biology. I've dialed your intensity back 15-20% for that phase.

🧠

Knows your body better every day

Follicular? Luna can push harder. Luteal? She can help recalibrate. Lune keeps your cycle, recovery, and health context in view — not just textbook averages.

💬

Explains your body in plain language

Why you're tired in luteal. Why you peaked last week. What's coming next. Real answers, not generic advice.

🤝

Validates the hard days

When your energy tanks, Luna doesn't push. She validates. "That was hard and you still showed up" hits different when she actually understands why.

What Lune is not doing

No paywalling your own body.

No fake annual sale countdowns.

If there's a real founding offer, it will be real. We're not copying the forever-sale playbook women already hate in other apps.

You shouldn't have to pay to understand your own body.

Lune can charge for coaching and programming. It shouldn't hide basic body literacy behind a wall and call that support.

Tell Luna about low energy, recovery, or perimenopause. It should feel useful.

The point isn't to force you through a perfect plan. The point is to make training feel more realistic for your body, your week, and your actual constraints.

      Questions

      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. You still get workouts that respond to how your body is actually performing; they just aren't phase-driven.

      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 instead of treating the four phases like a rigid rule.

      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.

      Do I need to track my period in a separate app?

      No. You can log everything inside Lune if you want a single app. If you already use Apple Health, you can import period history so you don't have to re-enter those dates.

      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. It's our thank-you for betting on us early.

      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 the male-focused research it's compared against — which is part of why Lune exists — so we're transparent about what's well-established versus where we're making informed calls. See the 10 peer-reviewed studies we draw from.

      When does Lune launch?

      We're building toward launch based on real signal, not a vanity date. Waitlist members get early access first and an email a couple of weeks ahead of when their access opens.

      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. Full details in our privacy policy.
