I've been using Android for the past four years, and today is the first time I've paid for an app. (Thanks, Google Opinion Rewards!)
Not that I'm using pirated softare. It's just that everything I needed to do, I can do with free apps. Now that I've started commuting to work again, I'm in need of an app that shows the train schedules. I've tried a few, and the best so far is TripView Sydney. You set two endpoints (train stations), and it shows you all the combinations (routes) between the two, sorted based on arrival time. What I like about TripView Sydney is that I can tell from a glance how many trains I can afford to let go without missing my arrival time. For example, there could be 4 trains leaving station A, different trains on different platforms, but they all end up at station B at the same time. This means I can take my time and walk at a slower pace.
