Toggl is a time-keeping app for logging one’s hours spent on projects (or anything, really).

A technical communicator may juggle a variety of roles as an independent consultant for multiple clients as well as a full-time student. You might need something to track your billable hours, as well as to record how much time you spend on schoolwork, so you can prioritize better and make time to have a life.

Similar apps that may be found on the Google play store include Timesheet, aTimeLogger, Time Tracker.  But I really love Toggl; I’m toggling right now.
