Flock apps are not just for power users

Using apps should be effortless. Flock apps not only provide slash commands for power users, but also a slick GUI interface for those of us who are command-line challenged. So, you can easily click your way through apps on Flock. Or stick to memorizing complex commands on Slack

Go beyond messaging with To-dos, Polls & more

Create and assign tasks, get notified of updates and more with Flock’s built-in Shared To-dos

Conduct live rich polls, with images and anonymous voting

Automated mailing lists for each channel so you can send emails when chat is not the best medium

Smart membership rules for channels

Need a channel for all software devs in the Boston office or one for everyone reporting to Mark? Flock’s Smart Channels allow you to set channel membership rules. Employees meeting the criteria will be auto-added to the channel. Slack teams will have to add channel members one by one
