Curious as to how PasswordMaker either uses weak crypto or "suffers from critical flaws". Master Password seems to be more flexible with features like password counter and a customizable password policy (this is especially cool if it is customizable per domain). Unfortunately for me iOS-only is a deal breaker. PasswordMaker has clients that run on everything. The two I use most are the "PasswordMaker Pro" Chrome extension and the PasswordMaker X Android app.
Hey, thanks for linking to my PasswordMaker app! :) I saw this linked on /r/programming earlier and mentioned it there.
I'm not sure how the password counter and "customizable password policy" (I'm assuming this refers to the password templating feature?) make Master Password more flexible, though. PasswordMaker offers plenty of configuration options you can tweak when you want to change the password for a site; I've begun creating multiple profiles as sites varying in their password requirements. I use the Chrome extension you linked to, as well, which auto-selects the profile based on the URL I'm browsing.
