These are the 5 most helpful SteemIt tools I have found so far. I listed them in the order I use them in, from all the time to once and awhile!
#1) SteemStats.com by
This is an epic all around tool I am constantly using. It lets you see all your posts and who's voting on them, not only that but you can see the power voters give to your post as well! All kinds of features packed into a great interface makes SteemStats my favorite SteemIt tool so far.
#2) SteemIt Notifications by
This tool is actually a browser extension that gives you notifications when you get comments, or new up votes on your post! This cuts down on refreshing a lot which is very refreshing to be honest with you ;)
#3) SteemAnalytics by
This tool is great when you're trying to figure out what you want to write about. I like how you can sort by the top 100 users likes and see the top performing categories. I'm sure this will even out over time but for now it really gives you a helpful idea of what people are interested in and willing to up vote!
#4) Steem-o-graph by
This little tool shows you all your followers in a pretty format. Careful if you have a lot of followers it can get pretty resource intensive, or that could just be because my computer is ancient. ;)
#5) SteemWhales.com
A cool rankings tool that shows you the top ranked users, and lets you page or search through the rankings. Currently I'm ranked #14081 which is pretty good.. um.. it's.. alright. Thanks for the helpful tool
