User Reviews

Users appreciate the app for its simplicity, speed, and accuracy in calculating pregnancy-related dates. It's especially valued by medical professionals for its minimal ads and reliable features. However, multiple users request features such as gestational age calculation based on due date, ability to select calculation dates other than today, cycle length adjustments affecting all parameters, and interface customization options to improve usability. Default settings like the 28-day cycle also occasionally lead to inaccuracies.

Pros

Simple and easy-to-use interface with minimal or optional ads.
Efficient and fast performance suitable for medical professionals like students, interns, and nurses.
Accurate and reliable calculations for estimated delivery date (EDD), gestational age, and related parameters.
Compact and user-friendly design without unnecessary features.
Allows adjustment of menstrual cycle length for better accuracy.

Cons

Lack of option to input gestational age based on a given due date (EDD) instead of just based on last menstrual period (LMP).
Default cycle duration set to 28 days, which may affect accuracy; some users prefer 29 days as default.
Changing cycle length adjusts only EDD but not gestational age, causing discrepancies.
No way to select a date other than today to calculate gestational age, limiting use cases like retrospective GA assessment.
No option to customize which calculation methods to display or to rearrange their sequence, leading to cluttered interface.
