Tracking which job you applied for is the least of the job applicant's concerns when looking for a job. In some circumstances the first step of the job application process is even fire-and-forget, and tracking those only serves to not apply again which is a zero-effort move.
Once you start to get a process going, emails and calendars already leave a good, easy to follow paper trail, and any need you might have is easily fixed with a text file/spreadsheet.
