There are many apps out there that could help us with our Crypto Currency Trading when we are away from keyboard, Here I post my selection.
Bitcoin Checker, is a light app to be aware always about prices changes, an excellent app. Over 80 exchanges and all currencies. The alarm feature is very customizable set it for percentage change, price greater or lower than defined value and value change, it even alert via Text-To-Speech. It is free but it worth a donation.
With this app i don't miss a chance to sell or buy a good price.
For a candlestick chart i use Crypto Trader, this app deliver coin price chart with short and long term SMA lines at a defined time lapse, sell and buy orders, trade history, volume histogram, MACD and signal lines along momentum histogram . It is great.
CryptoTrader shows me the candlestick chart for BTC, DASH, ETC, ETH, FCT, ICN, LTC, MLN, REP, XMR, XRP and ZEC, for Poloniex, Kraken and OKCoin and i don´t need more than this by now.
And of course Blockfolio, this app has charts and alarm, but I use it mainly for portfolio tracing, increase or decrease of market value against net cost. It has a news section awesome.
I exchange in Poloniex but it has no app, what it has is a great mobile web that works smoothly.
I do not decide yet for a wallet any recommendation is welcome. Those are the ones I use, the key for me is not to have an app that shows information i don't use, maybe there are better than the ones before but "Works for me!" (Hunter), keep it simple. If you recommend others please let me know.
