The app is not a bad start, but theres a lot of room for improvement:
(1) The app needs better Plenti integration: I shouldnt have to key in a Plenti number (thats entirely too long btw) AND switch apps to pay for gas- it should be all integrated or Exxon should ditch Plenti and work on an in-house solution (which given the returns are $1 for every 100 points -- or 0.01% return -- would not be a complete loss).
(2) I understand why Exxon is integrating Speedpass this way versus actually adding Apple Pay but there should be a deployment plan in place to integrate actual Apple Pay at the pumps over the next 2-3 years as I see mobile payments booming and eventually our phones will replace our wallets. Furthermore, if you decide to keep Plenti consider adding QR code versions of the Plenti card to the Speedpass app and adding QR readers to the pumps as well.
