I use the esteem app for posting at least one po post a day (on one post a day you get some free upvote) . It also autosaves drafts which is nice.
I have had some issues with esteem not actually publishing to the blockchain, but that was only once or twice and the post was saved so I just had to copy and paste and just post from steemit. It can be a little slow, but tends to be up and available even when steemit.com is down. There is also supposed to be an update coming that will coincide withSteemfest
