@cryptoctopus,
Actually I don't know about new Apps that are very useful. Yesterday I heard about Google Chrome extension which can be used to check Account status, but I don't think it might be a good tool for me, coz I hate to add plugins or extensions to my browser (Security purposes)
I am currently using

• steemnow.com
• steem.supply
• steemd.com
• steemdb.com
  as my main apps in this platform. But you just mentioned few useful apps in the article and I hope to give a try on them also! Definitely in this round I will not get your big fat upvote but hope in future I can receive that upvote from you!
  Thank you very much for sharing such great information with us!

Cheers~
