It was stated in the recent Priority One interview that the STO moble app *is* in development:
E: I want to ask a quick question about DOffs, when the DOff system was first introduced everyone was crying for some kind of an app that allowed you to check in on your doffs or do some missions, is that still on the table, what?s the status of it?
S: That is definitely on the table and we?re doing a little legwork right now on some lighter systems that don?t involve the DOff system but thats definitely something thats on the horizon, I wouldn?t say terribly soon but we are actively working towards it at Cryptic to get web and mobile integration into our games
E: Which team is working on that if you don?t mind my asking?
S: We have a core team that?s working on that, we have a UI team member that?s helping make the UI on star trek but other then that setting it up is off team, so you?re not losing Star Trek Online programmer resources to make this mobile app, we have an internal team that?s dedicated to that at Cryptic Studios
E: But they are doing it for all the projects that are on at cryptic right now?
