I love that it is so easy to use! It's very intuitive - you can do almost everything with just one click or tap of your phone/tablet screen (or mouse).
The interface could be more modernized but overall this app has been great for our business needs thus far as we've had no issues using WF in conjunction w other applications such office365 email etc.. We are able track all employees' hours from any device at anytime which helps us keep up-to date about when they need their next shift change / vacation request submitted through out day if not sooner than ever before possible!!
