I can agree with this too. Recently found a job after 50+ applications. I started with heavily tracking them, but in the end I lost the care in doing it. When a potential lead called me up it was to arrange an interview and so as soon as I got their details, a quick search of the company name in my Gmail revealed what I'd actually applied for.

If you're planning on writing something like this, perhaps a tool for the flip side would be better, i.e. an applicant tracker for organisations (although these do already exist).
