AI Analysis

Today's Dashboard

Most fitness apps make you start from scratch. Lune works with the program you already love — and makes it smarter.

AI Coach

Not just smarter workouts — a coach who knows you.

Luna

Your AI Coach

Good morning, Sofia! You're on Day 10 — follicular phase. Energy should be climbing. 💪

I feel so tired today though. Should I still do heavy legs?

Totally valid — your check-in shows low energy today. I'd swap to moderate intensity and focus on glutes & hamstrings instead of heavy squats. Your body will thank you tomorrow.

Why am I always tired in luteal?

Progesterone peaks in luteal, which raises your basal temp and increases fatigue. It's not weakness — it's biology. I already dial back your intensity 15-20% during this phase.

Ask Luna anything...

🧠

Remembers everything

Your goals, injuries, equipment, cycle patterns, and training history — Luna never forgets.

💬

Real conversation, not chatbot scripts

Ask why you're tired, request modifications, or get science-backed answers about your cycle.

🔄

Adapts every session

Daily check-ins feed into real-time adjustments. Bad sleep? Luna recalibrates your workout.

📈

Gets smarter over time

The more you train, the better Luna understands your unique patterns and peak performance windows.

The Problem

Fitness was never designed for your body.

♂

All fitness advice is designed for men

Most training programs are built on male physiology. Constant progression, same intensity every day. That's not how your body works.

⚡

Your energy isn't random — it's hormonal

That week you crushed PRs and the week you couldn't finish a warm-up? Not willpower. Hormones. And they're predictable.

🔄

Generic apps ignore your biology

Cookie-cutter plans don't account for the 4 distinct phases your body cycles through every month. You deserve better than one-size-fits-all.

How It Works

Smart training in 4 steps.

📅

Track your cycle

Log your cycle or connect your existing tracker. On birth control? We adapt to that too.

🧠

AI analyzes your phase

Our AI maps your hormonal phase and learns your unique patterns over time.

🏋

Get personalized workouts

Workouts that match your energy, not fight it. Intensity, volume, and type all adapt.

📈

See real results

Train consistently without burnout. Better recovery, better gains, better relationship with your body.

Why Lune

Built for women who take training seriously.

Cycle phases tracked & optimized

Powered personalization for every session

Science + Community

Built on real women's experience — not just textbooks.

BC-Aware

Birth control can suppress muscle gains — Lune adapts.

Hormonal contraceptives change the game. Most apps ignore this completely. Lune detects it and shifts your training to a general fitness mode that actually works.

Personalized

Ovulation isn't peak performance for everyone — Lune learns your pattern.

The textbook says ovulation = peak strength. Reality is messier. Lune tracks YOUR data and adapts to when YOU actually perform best.

Permission to Rest

The biggest benefit is knowing when to rest — Lune gives you that.

Women report the #1 benefit of cycle-syncing is the psychological permission to take it easy. No more guilt. Just smart training and strategic recovery.
