Pregnancyweek is a free iPhone app developed by Sabrina Holzer that allows you to easily track and monitor your pregnancy progress. With this app, you can stay informed about the current week of your pregnancy, the number of days you have been pregnant, and the countdown to your baby's birth.

One of the key features of Pregnancyweek is the pie chart that visually represents your current week of pregnancy. This allows you to see at a glance how far along you are in your pregnancy journey. Additionally, the app provides information on the current trimester, giving you a comprehensive overview of your pregnancy timeline.

To get started, simply enter your expected date of birth or use the date of birth calculator provided by the app. This calculates your baby's estimated due date based on the timing and duration of your last period, following the extended Naegele rule.

Never again will you forget which week of pregnancy you are in with the Pregnancyweek app. It is a convenient and practical tool for expectant mothers to stay on top of their pregnancy progress.

Key features of Pregnancyweek:

• Current week of pregnancy displayed in weeks and days
• Information on the current trimester
• Countdown to your baby's birth
