That's interesting. I'm the developer of Flow -- so don't take this the wrong way, but are you using the latest version of Flow? Or even a recent version? Because if you are, and you're not able to save passwords, then I'm sorry to suggest that you're probably using a "cracked" copy of Flow. (Cracking the binary causes the code signature to become invalid, thus barring the app from accessing the Keychain, where passwords are stored.)
In any case, you can grab the latest version of Flow (1.2.2 at the time of writing) from .
And, for what it's worth, if you *are* using old, outdated, and cracked copies of software, and reviewing them negatively for functioning incorrectly, then I must say that that's pretty low, sir.
