SW monitors your EQ report for certain changes and monitors your EQ FICO for changes as well. Included in the subscription are two free reports, with the first being used when you first subscribe. Upon renewal, you'll then get two more reports to use at your choosing. If you use up all of your reports (or the one remaining in your case), then future pulls for your EQ FICO report and score are 30% off (provided you pull via SW).
For best results, and I strongly recommend you do this right now, go to your target score and change the target to EXACTLY match your current EQ FICO. This way if the score goes up or down, you'll get alerted to any score change. SW will monitor your score for changes every week or so and if there's a score change, again immediately change your target score to match that score. It gets tedious, but it works and am alerted to each score change. In the beginning, I set my target to 700 when my current score was around 550. I realized my folly when I wasn't getting that many alerts.
Familiarize yourself with the SW Guide found stickied on this board. It doesn't catch everything, and like with all other CMSs out there, there might be up to a day or so delay in getting alerts.
