Train with your cycle,not against it.
Drop It is the first app that connects your cycle with your fitness, adapting every session to your cycle phase so your training, recovery, and energy stay in sync.
The way women train is broken.
94% of sports science studies exclude female physiology.
For decades, women have been training following systems based on men’s bodies. Drop It's the first performance system built entirely for women's physiology
Cycle & Symptom Tracking
Track your cycle and symptoms to understand how your body feels over time. Drop It turns daily inputs into meaningful patterns that guide your training decisions.
Personalised Training Sessions
Drop It creates personalised training sessions adapted to each cycle phase, combining strength, cardio and recovery. You follow and log each session live inside the app.
Adaptive Training Logic
Workouts dynamically adjust intensity, volume and exercises based on hormonal phase and real-time feedback, so your training evolves with your body—not against it.

How does it work?
We calculate your Readiness Score based on your daily energy levels, fatigue, and mood.
Our engine assesses how prepared you are each day, then adapts your workouts automatically to match your capabilities.
Our approach isn’t a generic Cycle Sync system – it’s a methodology backed by scientific evidence that will help you build consistent energy, reduce difficult days, and make progress throughout your entire cycle.
How is your energy level right now?
Barbell Bench Press
Move in sync with your body
Smart adaptation designed by sports scientists, engineered for real results.
Our algorithm doesn’t just make workouts easier. Created in collaboration with high-performance coaches and sports scientists, it intelligently recalibrates your training volume and intensity.
By adjusting weights and reps in real-time based on your daily Readiness, we guarantee you continue making safe, structured progress toward your goals without overtraining.

The performance engine behind drop it
Siena is the AI agent behind Drop It, learning from cycle, training and daily signals to support women's health, performance and consistency over time.

64 peer-reviewed studies.250 pooled trials. One algorithm.
Most apps decide how you train by counting days since your last period. This math assumes a cycle almost no woman actually has: phase length and symptoms vary from cycle to cycle and from woman to woman, and the methodological consensus in female physiology advises against predicting performance from the calendar alone.
Behind all of our sessions sits a reviewed research library spanning physiology, program design, and cycle-related conditions, including meta-analyses that pool hundreds of primary studies.
Drop It doesn't estimate.It translates protocols validated by science, into the session you're doing today.

Frequently asked questions
How is Drop It different from other period trackers?
Unlike traditional calendars, Drop It cross-references your cycle data with performance and recovery metrics. Siena, our AI engine, doesn't just tell you what phase you are in, but exactly how you should train today based on your daily energy levels.
