Buggy Hewlett Packard 15C Scientific Calculator iPhone App?

[Gerson W. Barbosa]

The HP-15C app by Hewlett-Packard returns blinking results after program executions (version 2.0.1, iPhone 4s and iOS 7 here).
This is not much of a concern, however. I would just press CHS (or x<>y) twice to stop it from blinking. The main issue for me is the default American number format which makes the app totally useless for me. Please correct me if I am wrong, but apparently there is no way to change it to European number format (DECIMAL POINT IS COMMA). May we expect more updates? Thanks!
