Not awesome but workable

It does what it needs to but its not "sophisticated". For example the charts. You can view chart in various increments (5,15,30min etc) or by time period (1day,week etc). But you cant set it to show you 10min candles over the past week. Or the order entry. You get a qwerty keyboard for something that can inly have digits, making entry awkward. Those are basic things! Features of this sort are available on bucket shop brokerages even, so why does IB not implement something more industrial strength? Oh, I know... They are not concerned about mobile app because hobbyist traders are not their core business. But still... I wish theyd spend a little money on a decent app design.
