The app has a data analysis feature. It determines the amount of money that users will earn if they take money from sources that do not bring income and make a profitable investment. We successfully created this function, but the draft version of the code took 30 seconds to load. This was too slow, so we used the recursion method. It made it possible to calculate all the data at the time of initialization of variables or their change and write them to the storage with subsequent use for calculating other forecasts. This way an app got a feature of analytical data forecast for the next 5-10-15-25 years that works as fast and efficiently as possible.


1) Overview page allows User to navigate into 3 sections of the personal balance and fill down items that he possesses to see the report on his possible investment opportunities and to be able to see deeper analysis after purchasing the premium subscription in the app. 2) Values input for Assets, Liabilities and Budget sections of the info. 3) Premium subscription page with integrated Stripe payment system. 4) Over time analysis page User is able to select parameters by which he wants to see changes over a number of years. 5) A User is able to select parameters by which he or she wants to see changes over a number of years.


We have developed a progressive web application (PWA), with versions for Android and iOS, to meet all the requirements of the Play Market, App Store*, and the FinTech industry in general. The application has implemented the functionality of reporting on possible investment opportunities, as well as a feature to see a deeper analysis after the purchase of premium subscriptions in the application. The functionality is quite rich. It is possible to see the total amount of expenses that the user has filled in. Users can select the parameters by which they want to see changes over several years with the help of our innovative algorithm. Also, an advertising placement function has been implemented. And of course, the design shows what the spring is like on Jupiter and Mars:)
