Smart Period Tracking
Trenpy is optimized with advanced statistical models to analyze your cycle. This technology predicts your next period, flow days, and PMS phases with the highest accuracy. It is a scientific and reliable assistant that leaves no room for surprises.
Ovulation & Pregnancy Tracking
Ideal for those planning a pregnancy or closely monitoring their fertility window. Accurately calculate your ovulation days and effortlessly plan according to your body's natural rhythm.
Daily Insights & Discovery
Trenpy is more than just a calendar; it is a guiding assistant. Every day, it offers personalized, insightful content to keep you informed about your cycle and help you understand your body better.
Smart Symptom Prediction
As you listen to your body, Trenpy learns from you. By regularly logging your symptoms (like cramps, headaches, or mood swings), Trenpy analyzes your cycle patterns and gently anticipates potential symptoms before they occur.
Comprehensive Medication & Supplement Tracker
Not just a cycle calendar, but your holistic health manager. Easily log your painkillers, vitamins, or daily supplements, and track your remaining stock. Personalize your list with custom colors and icons for a fully tailored experience.
Dedicated Birth Control Mode
Trenpy adapts to your contraceptive method with a fully dedicated mode. Whether you're on the pill, using a Hormonal IUD, Copper IUD, or have had a Tubal Ligation, each method is fully supported. Hide ovulation, the fertility window, or shift your calendar to alert mode if you're not planning a pregnancy.
Interactive Health Reports
Generate modern, clear, and interactive reports about your cycle and health trends. Read your body's language through data.
Sensitive Notification Management
Trenpy thoughtfully considers your every moment. Toggle the exact notifications you need and disable the rest. Most importantly, hide the content of symptom predictions and medication alerts from your lock screen for total privacy. You are always in control.
