I was trying out the service mentioned by @emrebeyler yesterday. Steem.rocks is a site that shows the activity feed for a Steem account. It shows new follows, upvotes, replies and even rewards. Most Steemit features might be seen on the site as the developments goes further. The site is relatively new, I think I am one of the first few contributing to this project. Incase you did not know, it is an Open Source project.
Homepage of Steemit.rocks
I was going through the site this morning, when I discovered it was showing a different voting power for my account. I compared with two other websites, Steemnow.com and Steemd.com. Both Steemnow.com and Steemd.com said I have a different voting power from the one showed in the Steem.rocks.
Let me take you through with pictures.
This is the voting power displayed in Steem.rocks. It says my voting power is 73.1%.


Conclusion
If you check all three images/screenshots above, you will discover they were all taken the same time, 6:53am this morning to be exact. Effects of wrong voting power are too numerous to mention.
Suggestion
I am no developer, but I will suggest that the voting power can be feeded from any of the other sites, or even from the Steemit site. Wrong voting power can be very misleading, it can make a steemian stop curating, till a certain voting power reached. I think this should be taken into consideration.
Additional information
I used UC Browser to access the website on my Samsung Galaxy Phone.
