Zach Gonzalez - This feature is actually available out-of-the-box now in the recent 25.1 release!

From the  release announcement :

Track Account Interactions: Improve your account relationships with immediate insight into the most recently held call or meeting, automatically displayed in the new Last Interaction field.

Check out either of the links in this post above to see some videos of this functionality in action. 

I hope this helps!

Thank you, I have been working in my sand box and that field wasn't there but I do see it in production! I did find a work around as my ultimate goal was to just know how many days it has been since the last interaction, but this will make my set up in production even easier!

Hi Zack (and Alex),

The new Last Interaction field also has a Focus Drawer!  I think the one "drawback" of the new Last Interaction field is it doesn't include the Last Email as an interaction.  Some others also want the Last Task.  Here is the Idea request from April:

I'm still using the Last Activity Add-On from Enable Services
