waited on the phone for 32 minutes trying to verify my account. looked up all of their small charges on 3 different cards, took pictures of myself and my driver's license and after all of that, they say the verification will take up to 72 hours. I'm sitting at the fuel pump now. absolutely ridiculous. been using this app for years without issue. i'll be looking at other discount options.

Just installed the app and few seconds later uninstalled the damn thing. Trying to make a route is not telling me how to get to the first stop, is making the route from the first stop and then running to the final destination. And in top of that, Everytime I touch the search bar to type in an address keeps bothering me with "Turn On WiFi for better accuracy" NOOOOOO, I don't want to turn on No WiFi to waste battery. Same as Hammer, unreliable apps.

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.
