About this app
Calendar at a Glance - Your last period, next predicted date, ovulation day, and fertile window all on a single screen. Flip through the calendar to see the flow of your cycle at a natural pace. Log with a Single Tap - Tap "Period Started" and the duration is set automatically. If it runs longer, just adjust the end date. You can leave short notes too. Predictions Grounded in Research - The algorithm is designed based on medical literature and statistical studies. It adapts to your recent cycle data, so predictions become more accurate the more you log. Your Data Stays on Your Phone - Nothing is sent to a server. No account, no login. Delete the app and your records are gone with it. Keep Sensitive Entries Private - You can hide sexual activity logs. They can only be unlocked with Face ID. No Unnecessary Recommendations or Ads - No talk of supplements or health products.
