I have been using smart fueling for about three years now, during this time it has worked very well at keeping track of my consumption so as not go over budget each month! The software also syncs across multiple devices such as phones/tablets etc which makes life much easier when traveling or away from home / office! Nothing specific really but perhaps more customization would be helpful like adding custom categories e.g.
gas stations near me (eg Costco) instead of having one default category…
