Wallets for phone include Bitcoin Wallet for Android and Electrum for Android.

For OTP generators, there is the official Google Authenticator, but I think that's bloatware and I use the FreeOTP one made by RedHat, it's also on the Play Store.


I don't know if there are equivalent apps for iphone / ios.


I also have my fiat banking apps on my phone, but it's really more to look at my balance when I use my accounts or cards. (debit cards, credit cards.)
