MultiBit HD is quick and easy to install and supports all major desktop operating systems (Windows, OS X, Linux) featuring a secure design (all data is encrypted and hardware wallets such as Trezor and KeepKey are supported).
It is compatible with the iOS App breadwallet, which is the only iPhone wallet which connects directly to the bitcoin network.
