I had created an free iOS application some time ago to follow live prices of coins you like to follow. You can easily create your own list and watch them , or list top coins , use radar feature to find top gainers or losers for the last hour or last 24 hours , exchange market rates for coins etc... ( nearly all the coins are available to follow ) . App is using the market apis to serve the data. Screenshots and appstore download link is below:
You can get it from appstore for iOS : https://itunes.apple.com/us/app/bitcoin-watch-ethereum-litecoin-ripple/id1188404703?l=tr&ls=1&mt=8
Thanks.
