I use Google Authenticator on iOS and Android. It's just a standards-compliant (RFC 6238) TOTP app, not anything Google specific. I've got six logins using it - gmail, Dropbox, Amazon (AWS), Github, Digital Ocean, and an internal service.
One thing that is a bit badly done - and I understand why - is making it easy to have "redundant duplicates". When setting up a new TOTP three factor auth account, I need to get my iPhone, iPad, and Android phone all together and manually type in the seeds (or QR code them) to all three to ensure I'm not completely screwed if I lose the only device with the magic tokens…
I'd love to have more of my important stuff secured with TFA/TOTP.
