I like all of it, but mainly how easy you can customize your own reports with mobileums' API integrations as well as its ability for multiple users in our organization (15-20) - who often don't have access directly to their email accounts - to work from anywhere using only smartphones! There really isn’t anything that we dislike about this product; however there could be more features added since they are currently working hard at adding new ones each month or so.
We use mobile um's dashboard daily just by logging onto my phone via safari browser. It has allowed us to stay productive during meetings which is great because then other employees aren't distracted/bored while listening when someone else talks too much instead. Being able to do some things without having everyone around me also makes life easier sometimes if i'm not.
