You don’t need an app to advertise Hive on twitter.. it’s called a tag #Hive.

In order for people to repost their Tweets to D.Buzz they were required to include the hashtag #Hive in their Tweet, or #dbuzz or $Hive.

The idea is that people on Twitter would backup their Tweets to the HIVE blockchain in exchange for using the hashtag #hive, please read our announcement post if you haven't already.

We took the site offline due to lack of support from major stakeholders of the community. @nathansenn will contact you today via Discord once you come online.
