Timely – This little web-based tool allows you to schedule your tweets. It supposedly chooses the optimal time for posts. I’ve been using this for about a week, mainly for my informational tweets (stuff that I find online or great blog posts from others that I like to share). So far so good… I like it. PRICE: FREE!
SocialOomph – Similar to Timely but a little more robust. SocialOomph has a TON of features for the power user to check out. I haven’t really used this one…not sure that I will. It’s nice and everything, just not for me. Some things you can’t automate – like relationship building. PRICE: FREE (Upgraded Professional Version: $29.97/month)
TweetDeck – Several versions available (desktop, iPhone, Android, Chrome), recently acquired/merged with Twitter. I use or have used 3 out of 4 (all but the iPhone version). With the desktop & Chrome versions, you can schedule tweets (and you can also pull in other social media profiles and use it as a central command center). I use this one to keep up with my Tweeps! PRICE: FREE!
HootSuite – Similar to Tweetdeck, I’ve only used the Android version of this one. There are a few features that I liked and a few that I didn’t like. I only really tried it out because Tweetdeck was acting a little ‘buggy’ that week. I have since uninstalled it because it was too similar and I really didn’t need the addition app on my phone… however, still a great little program. PRICE: FREE! (Upgraded Pro Version: $5.99/month)
