The ability to have an app that allows you to see what your customers are doing at any given time, it's very helpful! I think there could be more features added such as push notifications for when someone has visited my shop or restaurant/bar etc..
It would also help if we had access to our data so that we can make changes ourselves rather than having them do this every month which takes forever!! We use locatiy to keep track of who visits us during off peak times (e.g. lunchtime) and how many people visit each day.
