The UI looks very clean, easy-to use with no frills or distractions from other features that I do not need in my job (supervisor/employee communication).
It has been pretty useful for our team so far as we can now easily communicate schedules without having much trouble since it's integrated within Slack! There are some things they could improve like adding more options of different apps you would want your soon schedule set up using instead if only slack but overall good stuff!! We've used this feature extensively at work especially recently because its really helped us keep track all employees' shifts together which helps make sure everything works well between teams across departments etc..
