I found that I could just as easily find gas doing a web search. The app is useful but spams you to death in both email and text messages. Even after unsubscribing from notifications they still send them. I don't want a gas buddy credit card, or any of the other come-ons. In app ads are fine and a fair trade for a "free" app. Email and text are over the line for me. YMMV. Removing the app.
