Partiko is a new mobile app to use and interact with Steem blockchain on your Cellphone. What is most interesting about this app is that they don't take any cut when you publish from it.
I have personally explored many other Apps but Partiko has recently fast and interactive interface than others.
Personal Messaging:
You can directly communicate with other Steemians but both parties have to use Partiko messaging to use this feature.
Partiko Points
You can earn Partiko point for doing your routine activity via this app. For instance Upvote, Comment, Write post and even for daily checking out.
Redeem Upvote
You can daily redeem 3 upvotes from @partiko via publishing your post from their app.
There is only one thing missing in overall features and that was support of multiple accounts. I hope they would implement that soon in upcoming version.
