Designed to give you a full suite of options in one inclusive app, IG is a truly mobile stock trading experience. There are even separate apps optimised for use on each of the following devices: iPhone, Android mobile, Windows phone, iPad, Android tablet and Windows tablet. Better yet, the app is completely free to download and regularly updated. That being said, this one is definitely targeted towards experienced users, as evidenced by the in-depth analysis and market segmentation. IG is focused mainly on trading contracts for difference (CFDs), a derivative product because they enable you to speculate on financial markets such as shares, forex, indices and commodities without having to take ownership of the underlying assets. IG is definitely one of the best investment apps Australia has to offer, particularly if you’ve had a little experience before.
