No-one enjoys bill shock; well possibly some Australian telcos. Quota lets you track your internet usage, including data used over a 3G connection and over Wi-Fi. It includes a widget that you can add to your homescreen to see assess your usage at a glance. The full version lets you set up multiple accounts, and a wide range of telcos and ISPs is supported.
Another app that includes a widget, Weather Australia is pretty self-explanatory. Check the weather on the widget and load the app proper for more details, including forecasts and warnings. And a funky radar map.
ABC Australia News Widget
I love widgets; they're one of the things that make Android wonderful. The widget lets you choose from a range of story types, such as 'just in', top stories, sports, and world. Sadly it is quite limited — there's no option to change the shape or size — and you can't run multiple widgets with different feeds. But it's still a neat (and free) way of keeping up with the headlines from Aunty. It's not a thrilling app, but then quite frankly the official ABC Android offering is a bit crap.
TV & Movie Guide Australia
Apparently, I'm missing out on Dr Phil right now. Which, obviously, is no loss (I was originally going to rant about my Dr Phil-loving ex, but really what is there to say?) The free version of eBroadcast's TV & Movie Guide Australia is a handy way to check what's on and what's coming up on both the big and small screens. It feels a little sluggish at times (this is probably more an issue of data retrieval than the app). It has a few annoying issues: Every cinema is selected by default — I'd prefer if you could just select the ones you want instead of deselecting the irrelevant ones — and if you want to quickly navigate to a specific time and date to check TV times the interface is a little clunky. But hey, it's free.
