Hey, thanks so much for upvoting my recent. Personally I use  @mahdiyari's @Steemauto, as it has controls for how long after someone posts you want to upvote, as well as what % you want to vote for and what % threshold your VP should be at to allow a vote. Also, unlike Steemvoter, it lets you auto-vote an unlimited number of people and overall has a more user-friendly interface.

It also has curation trails and post scheduling and in the wake of Streemian's collapse, is really one of the best off-site resources for Steemit.
