From Dony George:
BitCoin Rate App consolidates market depth from multiple BitCoin exchanges to provide buyers with a Bitcoin Best Bid (BBB) exchange rate. The BBB is calculated by simulating an auto-routing market sell order, across all exchanges, with zero commission fees. The app will give the user the best bid exchange rates. The data is always updated every minute. The user can use pull to refresh any time to update the exchange rate. User can also view his wallet and see his balance in bit coin wallet. The wallet also lists the previous transactions. We only list transactions and do not do transactions through this app
