We'd like to invite you to try out CEX.IO app, an official application for CEX.IO Bitcoin exchange. The app is available for free download for iOS (https://itunes.apple.com/app/cex.io/id1047225016) and Android (https://play.google.com/store/apps/details?id=io.cex.app.prod) devices. In the app, you can track Bitcoin price on CEX.IO and across other exchanges, as well as buy Bitcoins using your credit card. At the moment, you can use only cards linked to your CEX.IO account, but we are planning to release the ability to add a new card right in the app in the nearest time. Literally, you will pay 3.5% + $ 0.25 for card deposit and 0.2% for Bitcoin purchase. After that, Bitcoins can be stored on your CEX.IO account and you will be able to use them in the app as well.
