Hamloki is a free Android lifestyle app developed by NB Studios. The app is designed to help women calculate their due date and track their pregnancy progress. It provides accurate calculations of the pregnancy duration in weeks, months, and fetal age. The app offers two calculators: the Gregorian calendar calculator and the Hijri calendar calculator. The Hijri calendar calculator is particularly helpful for women in Arabic countries who rely on the Hijri calendar.

Hamloki also offers an ovulation calculator that can help women determine their most fertile days. The app requires users to input the date of their last menstrual period and provides detailed information about their pregnancy progress, including the expected delivery date, fetal age, and fetal development. The app also provides information about the current month of pregnancy, the trimester, and the upcoming trimester. The app is easy to use and provides accurate information that can help women prepare for the arrival of their newborn.
