I'm that someone, and it was written in a weekend on a jail broken iPod touch on iOS 3.2. So, its unlikely that it still works (and I wouldn't recommend using it even if you can get it to work). I long since switched (back) to lastpass due to the pain of managing ssh keys across multiple devices.
This is what really pulls me to LastPass. The zero to two clicks it takes to fill in a password is just too good.
