  This work deals with the development of android-based financial studio, an
integrated application for calculating tax, pension, zakat, and loan. Financial
studio can facilitate employers of any department and other individuals. The
application is developed using MIT app inventor-based android platform. The
financial studio has four computational modules, namely: (i) tax, (ii) pension,
(iii) zakat, and (iv) loan. The system provides an integrated environment for
performing aforementioned distinct calculations by integrating different
financial modules into a single application in a user-friendly way. The
statistical analysis shows that the application is effective to deal with
different financial calculations
