eSteem has been cool so far, no complaints.
Well, if you don't know what eSteem is, eSteem is a blockchain based mobile social application - powered by Steem

In essence, it is a mobile app for steemit. Although not the official steemit, it combines a lot of features and tools that makes it even better than the web version. It was developed by a steemit witness @goodkarma

• Just like the web, you can login. Although you can't signup.
• You can view all your stats in-app. You don't need an external web tool to view your voting power, number of upvotes, etc
• It also shows you all your activities, who you upvoted, who uovoted, who followed, who commented, etc all in one page
• You can schedule posts and choose when they'll be posted
• You can adjust your voting percentage even if your steempower isn't yet up to 500
• A user friendly interface
• Multiple account login
• Inbuilt security (Pin Code) to access the app
• Multiple languages
• Multiple currencies
• And my personal best, It has NOTIFICATIONS. Notifies you about upvotes, comments, follows, etc

• None that is too bad to handle
  I hope the developer @good-karma adds in a calculator feature.
