If you mean that you are looking trading app for your mobile android phone yes there are too many of them. Usually, a trading platform has always a trading app, you can simply scan the QR code for the app. But why you prefer on the trading app? The disadvantage of that has a small screen that you might always be zooming the screen unlike if you are using pc/laptop it is very easy. I suggest having a blockfolio app because it is very easy for you to monitor when you are on travel.
