I've tried many, and keep going back to blockfolio. One app that was different and interesting was Delta which is worth a try, and Coinstats is great because you can tap to switch between favorite currency valuations on the fly. But at the end of the day I keep returning to Blockfolio, because when the charts are working properly, it's the best one out there still... sadly.
