Designed to track the overall performance of personal investment portfolios, it provides a comprehensive view of various accounts, stocks, funds, and cryptocurrencies. Utilizing True-time Weighted Rate of Return or the Internal Rate of Return, Prime Performance allows users to accurately monitor their portfolio's performance. As an open-source project, the app is freely available for download and use. Initially, the mobile application acts as a companion to the desktop version, enabling users to open the same portfolio file and access asset statements and key performance indicators. Please note that the app's design context solely focuses on the mobile application.
