I think calling it a PIN and asking for it so frequently is part of the problem. It certainly induces me to use a shorter one than I would otherwise like (since I keep having to enter it so often _right_ at the time I am trying to use the app).

Asking for it once at the time of a new registration, install, or a restore/reinstall would be far more preferable to me. Treating it more like a "filevault" key or an "encryption phrase/password", would certainly encourage me to use a much longer key and just put it into a password manager (and/or write it down and put it somewhere physically safe).
