I love that it syncs my calendar, tasks or projects with google! It's very easy to use as well - simple drag & drop feature allows me to organize almost everything about work in one app (ease of scheduling meetings).
The price should be reduced at least 50% so we can afford more features like project tracking etc.. Also maybe add option to sync calendars between different devices? Great way how you keep track what your colleagues are doing within an organization when working remotely/from home office by using this software.
