They did hire a full time mobile engineer, but I'm not sure how much he's been working on the current app. I believe most of his time is spent on a project to rewrite the mobile app. It's not released on any app stores yet. I'm actually slightly worried about this, since as a software engineer I know that rewrites tend to create as many problems as they solve... but they did mention the existing app will remain available but won't receive updates.

The number of mentions on this list indicates mentions on common posts plus user suggested alternatives.
