The accuracy when using it for building tracking was great as I used its API integration into our internal system which allowed us track visitors throughout their visit time within an office space or even across multiple offices via one single account! Also we were able use this tool through mobile app too so that helped me keep my hands off desk during those working hours while also being more productive at work itself!! Nothing really but i find some minor issues about how easy they can be fixed up if needed would make them better than other similar tools out there like Google Maps etc.
Maybe adding option where users could share data collected by situms internally? This will help improve user experience overall since people are less likely going around asking others questions instead just sharing knowledge amongst eachothers easily without having any problems doing such thing before now. !
