Great app and great customer service (Brittney ) did a great job helping me with some questions and extremely great attitude and professionalism.

### 4/5 — Steven & Arlene

*2026-08-13, version 3.39*

First time using the app. Very easy, select your fueling station, get your code, enter and save. Few more days on the road will be the real test.

### 5/5 — Great service

*2026-08-12, version 3.38*

Great company with great service

### 5/5 — Easy to use

*2026-08-12, version 3.38*

Super easy set up

### 5/5 — Best Fuel card I ever have

*2026-08-12*

I have been driving over 25 years over the road and this is the best card I ever have 
The only one thing that I don’t like on this card is that it’s not working in Canada. It would be really nice if you guys can make it happen to work in Canada and if you may can make it for a drivers that can pay a scale oil and some supplies that they need for a truck or repair so we do the same that would be amazing but that’s just suggestion but other than that is the best card on the road the best discount that exist

### 5/5 — Savings

*2026-08-11, version 3.38*

Great way to save money

### 2/5 — Use it couple times a year

*2026-08-09, version 3.38*

It can’t beat the discounts on other real fuel cards. But sometimes it will give you a place with a real good discount but that’s it

### 5/5 — Great customer service!

*2026-08-08, version 3.38*

Great savings!

### 5/5 — Top tier

*2026-08-07, version 3.38*

App works great and they got awesome customer service. Some of these companies need to take notes.
