This app is for calculation of inheritance according to Muslim laws:
This is not just a calculator, rather an assistant because it can covers more than 45 heirs but did not ask about all heirs in a single screen / page, instead it ask about heirs step by step minimizing the queries for eligible heirs only. Complicated calculations now made easy by this app.
Usually it will give the result in single or couple of screens / pages, but in rare cases if no eligible heirs are found then it will keep asking until it found eligible heirs.
