Pixlr Express (free)
A fine alternative to Snapseed et al, Pixlr Express delivers over 600 effects, adjustments, overlays and frames, plus it allows you to add text to the sharp images taken by the G2's 13MP camera. If you’re a lazy bones, its Auto Fix button generally spruces up a picture’s brightness, contrast and the like very effectively, all in a single solitary tap.
Forget Google Maps. Get some good karma with social mapping app, Waze. The navigation app relies on its users’ activities to update traffic situations. The combined data from users’ travelling speeds and updates allows Waze to calculate the optimal route and warn them of potential congestion along their pre-determined route.
Xbox 360 Smartglass (free)
The LG G2 already has an IR blaster built into it to let you control your TV and set-top box, so why not download the Xbox 360 SmartGlass app and let your G2 control that too? It's free after all.
Kingsoft Office (free)
We weren't even aware that there were even 23 different types of spreadsheet, presentation and text files, but this free does-it-all productivity suite can open and edit them all, transforming your G2 into a pocketable office. Minus the water cooler and secretary.
Alarm Clock (S$2.99)
This rather attractive alarm clock app lets you set custom multiple alarms and has a nap and sunrise feature to wake you up at the local sunrise. Or if you want to get really fancy, you can use the sleep cycle option which wakes you up in the lightest stage of sleep closest to your set wake up time for a less stressful morning.
