Tweet Jukebox is an online tool that you can use to build up your Twitter following and interactions with.
As soon as you sign up to Tweet Jukebox it comes preloaded with one Jukebox of tweets. A jukebox is simply a collection of tweets. The preloaded tweets are quotes which are really popular on Twitter.
You can set Tweet Jukebox to send out your tweets a certain number of times a day and the times it sends them out.
You can also add in another Jukebox for free and add in your own tweets. You can also attach images to your tweets which is handy.
With the free account you can only connect on Twitter account profile but you can register separately with each account.
The free account limits the amount of tweets in one jukebox and if you take the paid account from $9.95 you can have more tweets per Jukebox, more than two Jukeboxes and you have no limit on the amount of tweets you can send out in one day, plus you can connect more than one Twitter account.
I used Tweet Jukebox for a while and I found it very helpful as other tools like Buffer and Hootsuite you have to keep adding in your content. A jukebox keeps sending out your content so you don't have to schedule content in again once you have entered it.
I have now found a much more powerful tool (Mass Planner) and left Tweet Jukebox, but as a free tool to get started with I highly recommend you check it out!
