Mobile APP Finance

AN APP that enables small business and online entrepreneurs to TRACK their INCOME from various projects. SO for example maybe I teach tennis and want to OPEN a new TRACKING PROJECT called TENNIS I want to be able to enter in all the income from my tennis business and all my expenses and see graphs and charts and pull a PnL on just my tennis biz then lets say I also created a product I sell online..I want to be able to open a new project for that and track income and expenses from just THAT product...etc.. and I want to be able to SEE OVERALL PnL and income / expenses from all my projects combined...and download all my stuff into EXCEL if i needed to give it to my accountant for taxes etc..
