Windows Phone users don’t have a lot to choose from when it comes to Bitcoin apps. Bitcoin Wallet for Windows Phone 8 or later is trying to make this change. This is the first Bitcoin client app for Windows Phone and allows you to carry your Bitcoin with you at all times. It uses Windows Phone 8 features so you need that or later in order to be able to use it. Standard transactions are supported (no multi sig transactions) and you get a single receiving address. Real bitcoin support available with full purchase. Other cryptocurrencies are not available at this time.
Bitcoin Wallet can be used in combination with Bitcoin Can for traders on the Bitstamp, BTC-E, Coinbase and CampBX markets, and has nice tickers and you can easily view your trading history.
Other common bitcoin apps that work on Windows Phone are the MegaDice Bitcoin casino and the blockchain.info wallet/website hybrid.
To summarise, Bitcoin apps on Windows Phone are still few and in beta, but if there’s a will, there’s a way.
