ROI Personal Finance App

ROI is a project of our existing client for whom we created another financial platform – Defero.

Eigil, the founder of Defero and ROI, is a real guru of financial management. And we’re passionate about technologies.

That’s how we managed to create together the ROI app – software that helps users manage their financial assets and generate a passive income, as well as analyse their current economy and clarify precise ways to improve it.

Challenge

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 an 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 record them for subsequent use for calculating other forecasts. This way, the app was given the feature of analytical data forecast for the next 5-10 and 15-25 years that works as fast and efficiently as possible.

Results​

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 a 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. An advertising placement function has also been implemented. And of course, the design shows what spring is like on Jupiter and Mars.
