I use Bitcoin Checker. You can choose your market (Mintpal, Cryptsy, Bitstamp, etc.) and choose the currency (DRK, other, other, etc.)
I recently switched to this too. Great app. They need to add some new DRK/USD and DRK/BTC markets in the app if you wanted to leave feedback to the author

Has anyone contacted CMCap to add Ghash and BFX DRK markets ?
