This app is an absolute racket. 5 times I've driven out of my way to stations this app said had good prices, updated within the last hour, and 5 times the prices were higher than every station I passed on the way there. Tonight I went to one that said 3.09, updated 3 minutes ago. I get there, 3.29. Complete scam. Also the sign in doesn't work, it's just an infinite loop of enter email, check email, open link, app still not logged in. If only there was some sort of PASSWORD I could use.
