The Optimus G comes with the usual set of organizing apps and there's a preloaded document viewer and editor.
The app in question is Polaris Office and it's one of the most advanced mobile editors we've seen. You can of course view documents - Word, Excel and PowerPoint documents and PDF files too.
Edit mode offers almost a full set of options - text style, justification, paragraph formatting, bullets, even creating tables. If you're editing an Excel file, you get a formula wizard, resize rows/columns, border style, merge cells and so on. Even creating a full PowerPoint presentation is possible.
The app also doubles as a file manager and integrates with Box.net.
The calendar app has a split screen interface - the top part is reserved for the monthly calendar and one on the bottom for the agenda/daily/weekly view. This way you will always have your monthly view visible. The border line between the two sections is not fixed and you can easily move it. You can hide the monthly view completely, but you can't do the same with the other section.
In case you want to enjoy the calendar in full screen without any additional views, just turn the phone landscape.
Adding a new event is quick and easy, and you can also set an alarm to act as a reminder. You can also view events from three different calendars: your phone, your email and Google groups.
The LG Optimus G features an alarm clock application, which allows as many alarms as you need to be set, each with its own launch time, sound and repeat pattern. You can enable application link, so the calendar/email/music player/ tasks/weather app launches after the alarm goes off.
There's also a clever feature called puzzle lock, which will make you solve a simple puzzle to disable the alarm. This way you will only be able to stop the ringing when you have properly woken up.
The Timer, World Clock and Stopwatch features are also part of this app.
The organizer package also includes a useful voice recorder and a nicely touch-optimized calculator.
The Memo app allows you to take notes and add media to them, such as images, audio, or location.
The so-called QuickMemo function is integrated in the phone's OS, allowing you to capture screen shots of anything (including the lockscreen!) and scribble notes over them like you would on the LG Optimus Vu. A simultaneous press of the up and down buttons of the volume rocker will take the screen shot.
There are also Yahoo-powered weather, news and finance apps - any issues you might face with those can be resolved by downloading one of the many alternatives from the Play Store.
