Simple easy-to-use interface with many options available for customization. Also very intuitive once you get used it! I have no complaints about this software so far as we are just getting started but there really isn't much else out there like timer right now - if anyone knows of other timers please let me know!! We use time tracking in our business and need an app/software where employees can easily track their hours without having access to any accounting or payroll systems (which they do not want). This allows us to keep records straight when doing reporting at tax times etc.. No problems here yet though since its new product. Easy set up process from start to finish took less than 5 minutes compared to others which take days / weeks depending upon how complicated the setup was before hand. It tracks all aspects including client billing information. Very simple to add.
