Concept
This application mounts only the necessary minimum function.
I think that it can be operated also with the elderly and people of presbyopia by pursuing visibility and the simplicity of operation.
It is also recommended as a phone book for beginners, and I think it's convenient because it can telephone only by the cursor key and a determination key if it is a terminal with a hard key.
