All of the online wallets mentioned above and most of the desktop wallets have mobile versions, while others (such as Abra, airbitz and bread) are created with mobility in mind

Hardware wallets - hardware wallets are small devices that are sometimes connected to the network for bitcoin transactions. They are very secure because they are usually offline and therefore cannot be hacked. However, they may be stolen or lost along with bitcoin belonging to the stored private key. Some large investors keep their hardware wallets in secure locations, such as bank vaults. Trezor, keepkey and ledger and the case are obvious examples

However, they are more likely to be lost
