Yardbook offers a set of pages which are optimized for Employee access:

Admins can grant Employees limited access to these pages.

Not only do these views provide real-time access to some of the most critical features from the field, these pages are also optimized for mobile devices so that they are fully functional on smaller screens like a smartphone.

(Note: you need internet access to use these pages. Yardbook is planning to offer a mobile application in the future which can work both online and offline)
