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.
