Startup Idea: Personalized Finance Tracking Software

Startup idea to develop a comprehensive finance tracking software. The software will help users track their net worth, total income, investments, and integrate information from several different online and bank accounts. This is not an automated investment program, rather it assists manual tracking and does automatic calculations real-time.

I need a program that will help me keep track of my net worth, total income, investments and more.

This program would need to integrate information from several different online accounts and bank accounts. It would also need to keep track of investment history and projections.

Please note, I am not looking for an automated investment program, I am looking for a program that will just keep track of everything that I do manually and do calculations for me automatically and it really time so that I can always see how much money I can afford to spend at any given moment. I have tried to use the program called betterment online, but it doesn't do what I need. Instead I currently use microsoft excel to meet my needs.
