## What is Mirideum?

Mirideum is an iOS app designed for quick period logging and seamless calendar integration, helping you track your cycle and plan your days with ease.
Go beyond just checking your next period date. Visualize your entire cycle—Menstrual, Follicular, Ovulatory, and Luteal phases—at a glance, and balance your upcoming schedule with comfort.

[Key Features]
- Effortless Period Logging
- Quick Tracking: Easily log the start and end dates of your period.
- Simple & Clean: No complicated forms. Keep only the information that matters to you.
- Apple Health Integration: Sync flawlessly with the Apple Health app to manage your data in one place.
- Smart Estimates: View upcoming cycle patterns based on your recent logs.

[Calendar Sync for Smarter Planning]
- Period Predictions on Calendar: View your predicted period dates directly alongside your personal schedule.
- Visualize Your Cycle Flow: See your ovulation window and cycle phases integrated into your calendar.
- Prepare Ahead: Check your body’s rhythm before scheduling trips, workouts, or important meetings.
- Stress-Free Planning: Balance your daily plans with your physical changes to prevent burnout.

Track the 4 Phases of Your Cycle
Mirideum clearly maps out the four distinct phases: Menstrual, Follicular, Ovulatory, and Luteal. Easily identify your current phase, anticipate upcoming changes, and better understand your daily condition.

Gentle Insights for Mind & Body
On days when your heart feels heavy or your body feels a bit different, Mirideum offers thoughtful insights based on your current phase. We don't define how you should feel; we simply help you mindfully observe your natural rhythm.

Mirideum is Perfect For:
- Anyone looking for a quick and simple way to log their periods.
- Those who want to see their predicted period dates side-by-side with their calendar events.
- Anyone wishing to better understand how their condition shifts throughout their cycle.
- iOS users wanting a more intuitive way to view their Apple Health period data.
- People who like to check their body’s rhythm before making major plans.

Mirideum does not make absolute predictions. Based on your recent logs, it provides thoughtful estimates to help you prepare for upcoming changes and plan your schedule more comfortably.

Light logging, comfortable planning.
Start shaping your day around your unique rhythm with Mirideum.
