First of all, I'd like to thank Hive account@dragosroua for this amazing application. I've been using this ever since I started months ago and it's been great. It keeps my hopes up. It's one of the things I check first thing in the morning, before I go to sleep and everytime in between. What can I say? I'm addicted to it, lol. Anyway, it is very helpful and some Steemians don't know about it yet. Especially the new ones. So I'm posting this guide for those people.

I am going to use Hive account@steemph's account as an example here:

So, what are the things you need to know about this application/website?

It is very useful.
It keeps you up to date on how much you would receive.
And tons of other information!

The Basics

How to go there?

Simply type "steem.supply" on your address bar followed by the desired username, example: steem.supply/@username.

Up the very top of the website are 2 functions:

Rewards Calculator will take you to http://steem.supply/rewards which gives lots of information how your rewards are being calculated and you can make samples in it too.
There's also the account lookup, just type in a username and it will give you a sneak peak on how much they would earn.

After that, there's a box that shows your profile photo:

It also has your age, current voting power, and current vote worth there.

There are more 'financial' stats in the first box. These things are pretty self-explanatory.

alt

Delegated are the SP you lend to another Steemian.
Received are the SP delegated to you.

alt

That's the total value and Steem equivalent of the rewards being distributed for the next 7 days. It also shows the percentage your account is getting from the pool.

There's a very important part after that: Supporting the creator.

So, if you want to thank Hive account@dragosroua for making this thing possible, one way is voting for him as a witness.

Then comes a breakdown of how much you will potentially receive in the next 7 days. It will show both liquid and invested amounts. Their SBD and SP equivalent.

This tool also now shows you price feeds of both SBD and Steem. As well as a convertion ratio between SBD:Steem.

alt

That graph is also a cool addition onto the website. It simply shows the conversion rate in the past 7 days in a graph form.

There are 3 main tabs at the bottom part of steem.supply:

Content Rewards
Content Insights
Social Insights

Content Rewards

This part shows a bar graph of your potential earnings running over the next 7 days.

It differentiates your rewards by SBD and SP in the graph:

As well as if they're from posts or comments:

There's also an option to toggle between US Dollar view and STU view (STU is the $ you see on the website):

Then there's the graph of the actual posts, their equivalent rewards, and a countdown for you to get those rewards:

Content Insights

I'll keep it short for this tab. You'll see 4 things here:

Graph for Top 20 performing posts
Graph for Top 20 tags you use that earns.
Numerical stats for your posts
Numerical stats for your comments

Social Insights

There's a graph of the ratios between how much engagement (upvotes) you're getting vs how many followers you have.
You're Top 20 Supporters
You're Top 20 Most Loyal

That's about it for what's inside Steem.supply. I hope you find this overview helpful. If not, shoot some questions below on the comments and I'd gladly answer it!
