Free!! Doesn't ever ask me to pay to get directions anywhere. That alone should get you to download this app. However, it doesn't understand "truck entrance" - at every destination it takes me straight to the building, or tells me to turn at the visitor/employee entrance. I know the app's focus is on fuel savings, however it would be nice to see larger truck stops listed, mostly for finding parking along route.

We have been using the Mudflap App w/ fuel codes for over a year with no problems. I used to search multiple apps for the best pricing and location. That was a headache. With Mudflap we always find stations on our route and we found the discounts to be competitive. We just ordered the Mudflap fuel card a few days ago. This will make fuel stops more efficient. We had a billing error recently. I call customer service. Katie was a pleasure to deal with. She had the problem resolved in minutes.

App is easy to use and has great features. Unfortunately, the verification process took almost 2 weeks to get done, and then it was only finished when I called, and it was escalated to management to get it finished. Also they show huge discounts on the app at first, but as soon as we made a large fuel purchase the big discounts disappeared and we are now only offered discounts of just pennies per gallon. I'm not sold on whether this was worth it or not. I'm hoping larger discounts come back.
