Startup Idea: Janitorial Task Management and Tracking App

Startup idea to develop a mobile app that facilitates janitors to log their tasks, receive alerts for cleanup requests, and visualizes the average time spent per task using graphs/charts. Additionally, the app should contain an electronic queue of duties for ease of tracking and progress monitoring.

I work as a janitor and have to manually log the tasks that I complete ona time sheet. I hand write the notes then type it up in an excel file. I carry a work cell phone with me in case there is an "emergency clean up" or am called on the PA system or pulled aside (in person) by my supervisor. It would be nice to have an app that would alert me about (clean up) requests that need my immediate attention and also be able to log my tasks within the app itself. I'd also like to track how long (on average) I spend on a spend on each task (mopping a specific floor, cleaning a specific bathroom, etc) with a set of charts/graphs. Currently in my job, there's really no way to keep track of my progress or have an electronic queue of duties I am responsible for.
