## What is FastSyncer?

Most fasting apps give every woman the same plan every day. Your body doesn't work that way.

FastSyncer syncs intermittent fasting with your menstrual cycle. Tell it where you are in your cycle and it tells you, every single day, whether today is a day to fast, how long, and what to eat — because the same fast that burns fat in one week of your cycle can backfire in another.

YOUR DAILY PLAN
• A fresh recommendation every morning: fast or rest, and for how many hours
• Built around the phases of your cycle — some days your hormones need fuel, not fasting
• Two food recipes every day, chosen for where you are in your cycle
• The essential vitamins and minerals your body needs most that day
• What to avoid today, so your food never works against your hormones
• A quick daily check-in adjusts the plan to how you actually feel
• Works for regular cycles, irregular cycles, and menopause

28-DAY CHALLENGE
• A guided challenge that builds the fasting habit day by day
• Daily check-ins and gentle reminders
• Streaks, medals and progress rings that reward the work you put in

COMMUNITY
• Share your journey with women on the same path
• Ask questions, post wins, cheer each other on

FASTING TIMER
• One-tap timer that follows your daily plan
• See your fasting history and progress

WHY CYCLE-SYNCED?
Research on women's metabolism shows hormones change how your body responds to fasting across the month. FastSyncer puts that science in your pocket: rest days when your body needs nurturing, longer fasts when your body can handle them.
