Fuelio for the Leaf

I am just wondering if you guys know whether an app similar to the Fuelio app for ICE cars exists for Leaf in particular or EVs in general. I am not talking about the apps where you need to have an account (NissanConnect) and then it imports data or something. What I am talking about is the straight forward app where you enter your odometer readings and how many kWh you charged. Would be great if this kind of app has an integration with smart electric outlets. Thank you
