Startup Idea: Side-Hustle Revenue Tracker App

Startup idea to develop an iOS application to track the revenue from multiple side jobs such as Mechanical Turk, couponing, MyPoints, Amazon Seller etc. The aim is to replace manual spreadsheets with a more instant, efficient, organized app for income tracking.

I have a lot of side work that I do to earn additional income (every little bit counts!). Mechanical Turk, couponing, sending off for free samples, MyPoints, Amazon Seller, etc... It all adds up and I wish there was an app to easily keep track of which venture generated the most revenue. Right now I use an Excel spreadsheet on my computer, but it is not as instantaneous an an app for an IOS device would be. I would pay for this app, but I would not want to pay anymore than a dollar.
