I installed this app after linking my Plenti rewards account to my Speedpass account. Turns out this app doesnt support Plenti, only the Speedpass keyfob does. So I lost Plenti points by paying with this app. If you do want Plenti with this, you have to pull out your wallet and swipe your Plenti card frist. Which entirely negates any benefit of using the app. I recommend not using it. Just get a Speedpass keyfob, or else use your card. Also very thoughtless of the developers not to make this more clear. I feel cheated.
