One thing I'll miss from middlecoin is the simple android app that I put my BTC address into, and it would poll the site and display my stats. There's 2, one called Middlecoin and Middlecoin Monitor (the better and faster of the 2).
I don't know what is involved in putting an app like this together, but you may want to make something like that, or maybe start with a mobile sized page that I could have up on my phone that I could just hit refresh on.
Well, the API was just released a couple of days ago, and it's a temporary API that may change quite a bit yet, but we do have wafflestats at
http://waffles.wilschrader.com though this is better for desktop than mobile. I've never actually tried it on my phone, I might just do that and see how it looks.
I suspect other apps similar to what's available for middlecoin will pop up soon.
