Comments on FAST Pregnancy Calculator for Android

★★★★★ Sameera Nanayakkara · Oct 25, 2025
Extremely useful, user-friendly But need a little modification for this to be perfect. Need to have the ability to calculate the POA with an accepted ultrasound corrected EDD. The available feature is useful if somebody has failed to document the scan corrected EDD, which the machine automatically gives. But in followup visits, need to calculate the POA with a previously corrected scan EDD.
★★★★★ Ali Orhun Şafak · Jun 10, 2024
Oriented to physicians, this app did and will help directly its target, physicians, and indirectly the patients, no doubly. Very well done here.
★★★★★ Destiny baker luckey · Jun 3, 2021
