I looked into the app a little bit and a few things I see that set it apart from the ones I'm familiar with: - Sync is optional: it is a premium ($4.99/yr) feature that is not enabled by default. Other tools I've used have iCloud sync turned on by default. - Auto-lock: you can set a password so that some guest user who might be using your computer can't just open and copy your codes. - Backup code storage: you can store the backup keys in the app. (Kinda strange, since if you have access to the backup codes, you also have access to the OTP itself so /shrug/). - Keys are availabe: most of the apps I've used do not allow you to see the key after creating the account, but this does. Whether these are good or desirable features, they are somewhat distinct from the apps I've used.
