Does Bitcoin really stored in a phone software? I do remember that Bitcoin can be stored in a ledger wallet which is a hardware and not a software. Bitcoin uses a private key which you can access anywhere and that private key is what needs security and not the phone.
Yeah you can download a few apps for that. There's Mycelium, which is somewhat secure. It requires your pin every time you make a transaction, which isn't hard to figure out, but it's better than nothing.
