New app?

Ever since Translink has asked me to take down my Go Card app (and ironically at the same time when I was beginning to earn a drastically increasing amount of profit from it) I haven’t done much with apps, other than create a reasonably fun zombie game. I’ve noticed my Go Via app still sells about 5-10 units a week, and I might release an update for it if I can think of anything people might like. As for a new app, I really need to get some ideas together.
