A mobile app that allows you to track all of the TA hours for every class and send it directly to your Professor for approval. It is the job of every Teaching Assistant (TA) to keep track of all working hours to make sure you get paid for the work you did. As class assignments and responsibilities add up, it is very hard to remember the number of hours you worked, what exactly you did, and for which class. This is a very common problem amongst TAs in all universities.
