I like that it has so many features including but not limited to; reports/statistics (both overall as well individual), calendar of events & public access via website or mobile app! There are some minor bugs here n there which can be annoying sometimes - just keep at them until they get fixed!! It's free software though you do have options such as premium membership if needed.
The best thing about this program in my opinion would probably include ease-of use with all its various functions available through user friendly interface etc.. This helps save time by being able to easily navigate everything without having too much difficulty finding what your looking for within each section i.e., shelter info report schedule event information vet clinic records ect...
