Do you get a lot of messages that you need to take further action on? Do you mark them as unread until you've completed the task? If so, then RemindMe is here to help.
RemindMe allows you to set a reminder in your own timezone about a message in any of your conversations. That way you won't need to leave them marked as unread so you don't forget about them. Instead, RemindMe will send you a notification in your personal channel with a link to the message at a time you specify.
Reminders can be cancelled at anytime, and each reminder allows you to jump directly to the message. And the best bit is that unlike some other apps, all the reminders are sent in your personal channel and in the timezone you specify, so no one else in your team needs to know.
