Zakat Alfitr Calculator

The (Zakat Alfitr Calculator) app is used to calculate Zakat al-Fitr and its method of operation is that,
the user enters the number of family members, for example, the breadwinner, his wife, and three children,
making a total of five people. In this example, the user enters the number five,
then enters the value of the prevailing foodstuff per kilogram, such as the value of a kilogram of wheat,
or a kilogram of dates. Then he clicks on the "Calculate" button, and three results appear:
First: The number of family members.
Second: The total weight.
Third: The total value of Zakat for the family.
Application features:
The app interface is available in three languages, Arabic, Persian, and English.
The app gives the user three options for the calculation standard of the SAA measurement unit:

The first standard is the commonly known estimate of 3 kilograms, which is the default standard in the app.
The second standard is based on the opinion of Grand Ayatollah Sayyid Mohammad Said Al-Hakim,
which is one kilogram and 480 grams, and is close to some estimations of Grand Ayatollah Sayyid Al-Zanjani.
The third standard is a custom standard that the user can set if they have a specific theory they want to apply,
or want to add an additional precaution, such as Grand Ayatollah Sayyid Mohammad Said Al-Hakim\'s opinion of paying
three and a half kilograms as a ample precaution, which can be applied through the custom standard.
