I like how it tracks my hours worked/not - no more having to use an excel spreadsheet! The interface can be very slow at times when adding new dates or tasks which causes some lag in its responsiveness but that's not something we've had issues with since switching over from our old system (Mint).
It does require you install their app as well so they are making money off of your data if this bothers anyone out there who uses them :) Tracking paychecks has been much easier now than using Excel spreadsheets before because all payroll information gets pulled into one place instead of being scattered across different apps / systems used by employees working separate jobs within each organization.
