Since I got a review copy here is my honest review about Jarvee.
After installing that went smooth and opening the program, I got a little bit lost since there is a lot of features.
Not couple of simple ones, there's literally a ton of options that can be used to automate almost everything on FB, Twitter and Pinterest. Those are networks I used, but it also supports Tumblr, G+ and LinkedIn. I haven't tried last three since I don't have interest in these networks at the moment, so I can't say how well it performs there.
Facebook automation has most features and I am really satisfied with what Jarvee has to offer in this field.
I used it to schedule and publish posts on couple of my Facebook pages and share those posts to groups in order to expand my reach. It did almost perfect job there. I say almost perfect since I hit block once, but that's probably because I shared too much from one profile. After contacting support, I got detailed instructions about how to use share post feature to avoid blocking
Since I also occasionally boost my posts, the option to invite users who liked posts to also like page came in handy. It did the job as it should and I got decent number of new fans on my page.
Group finder and joiner tools also worked nicely
For Twitter I used basic features follow/unfollow, like and post tweets. They work as advertised. What impressed me is options for Follow tool sources. You can follow by keyword search, followers of other accounts, users from list of your choice, users who retweeted or favorited tweets of specific accounts...
Regarding Pinterest, I haven't done much there, since I'm just starting couple of new profiles. Just follow and unfollow, those tools worked fine. Couple of repins per day, which also worked fine till now - basically, I'm just warming up the accounts.
I used it for 6-7 days, support was fast and helpful, but if something changes in next month I'll let you know
Now, what I don't like is the fact that you have to keep your PC on in order to work, but it's a software, not web based so that's that.
All in all, good piece of software, complete automation for all big social networks, except, you know, Instagram.
If you are into FB or Twitter marketing, I highly recommend it since it does an awesome job on these networks.
