Samourai Wallet
Samourai is one of the newest anonymous wallets available. Unfortunately, the product is currently just in alpha, and you can only use it if you have an Android phone. Each time you receive bitcoin, the wallet produces a new address to prevent someone tracking your purchase habits. It also notifies you when sending bitcoin to the same address multiple times in order to deter unintentional address reuse. The wallet also includes other common privacy features such as TOR and VPN support, as well as blockchain obfuscation. To expand the anonymity to your phone, Samourai also has a stealth mode. This cool functionality hides the wallet from your home screen, launcher, app list, and recent apps. The only way to have your wallet appear is by calling a secret pin code.
