Recommendations for free job-search tools after 18 years as a marketing coordinator

I am tracking my applications in a notebook and want something better. I would rather hear the honest version than the polite one. I want reminders to follow up. Are there tools to avoid?

A simple spreadsheet with company, date, contact and next step was all I needed.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
