By default, Nikabot prompts you every day from Monday to Friday when you're active on Slack after 5PM. Team admins can change the time for everyone, but you can also change it for yourself.
If you want to find out what your setting is, sign in on www.nikabot.com and open your My preferences page or simply say
help to Nikabot on Slack.
Changing the time for the daily prompt
You can change the time when Nikabot asks you, in your My preferences page. You can also decide if you want Nikabot to ask you about the current or the previous day and if she should ask you even if you're away on Slack — otherwise, she'll wait until you get back online.
Remember that Nikabot uses your local timezone as defined on your Slack profile, make sure it's always correct.
