I use my phone and very rarely the pc. So far I tested pretty much every app Steemit related: busy, eSteem, steemworld, steemd, steepshot etc.
Currently, I use eSteem for posting, voting and commenting and Steemit site for editing my posts (it works a little better than eSteem who often gets stuck and does not show the preview accurately). On busy I check the notifications. Steemworld shows me who upvoted my posts, comments, mentions and different stats.
A good feature of eSteem is the fact that I can select the percentage of the upvotees I give (in the past I always exceeded the bandwidth as too many 100% upvotes given).
Steempeak sounds interesting, must be checked. 🙂
