I like that there are so many features in one place! It's not just about tracking time but also project management with PIPs (Project Invoices), task lists/gantt charts & reporting as well all within 1 platform which makes it easy for everyone involved - Team members or managers too!! We get daily updates from our Project Manager who can check progress at any point of day via mobile app by logging into their dashboard online using web browser anywhere anytime without downloading anything extra.
Nothing really dislike here yet however we do use this mostly during working hours only when available otherwise its offline mode where you cannot send messages etc., Also sometimes some minor bugs happens occasionally though nothing serious too :) This saves us lot more effort since everything gets collected under same roof rather than maintaining multiple systems separately across different platforms such as GSuite / Slack team chat rooms + Google Doc documents folder shared among colleagues internally.
