Love this App

I have really loved the convenience of this app and the additional savings it offers when I can use it. I only gave it four out of five stars because several times I have tried to use it and it would not work. A couple times I needed to fill up several cars or boats on the same day and it wouldn’t let me do more than one or two transactions. I would’ve loved to use it for all of my gas needs instead of just part of it.

Bring back the prices!

Update 4/2: this app just keeps getting worse and worse!! Now it won’t apply my 15 cent discount for my Sinclair card, and the prices listed are never right! I went into the store and had the ABSOLUTE rudest employee ever who refused to help and said she has never been trained on the app and doesn’t know how to use it, because she doesn’t buy her gas here. That doesn’t even look good, Sinclair!!! Come on now!! You are better than this. The update is horrible!! fix it already

Really not happy with the latest update. I liked being able to quickly look at the map and see the prices for gas stations in my area - now I have to click on each one individually to find prices. Very tedious and annoying. Fix the map and I’ll fix this rating!

It WAS a good app...

This Sinclair app was wonderful. You could pull up to the pump and quickly authorize the pump, it was intuitive easy and slick. The only thing I didn’t like about it was every once in while you would have to put in your user ID and password rather than Face ID. But just a couple weeks ago they changed the app to add advertisements and now it is torture. I’ve literally sat here for three minutes trying to figure out the stupid app to get the gas to pump. They had to put advertising on it so you could buy a bunch of crap on the card. Sinclair, make the app intuitive again. Make it easy to see without glasses. Put it back to the way it was-Blah!
