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.

You’re absolutely right that getting to the correct truck entrance matters, and we’ll pass that feedback along to our team. Give us a call at 1-888-885-3835 if there's anything else we can help with.

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.

Customer Service is terrible. Called multiple times for 3 months. Every time they said they would call back and I never heard a thing from them until I called back again. One "mistake" (fraud charge from 7000 miles away) and they'll take away your account. Verification team wont give a reason to their answer, nor can you actually talk to the verification team. No trying to work with you or figure out what happened, just done for.
