Nonna piera facile smartphone is a directory aimed mainly at those who want to use a personalized address book in calls but also at an elderly audience. This app was born from the need of my mother who is used to using old generation clamshell smartphones, not being able to understand touch smartphones, I wanted to simplify the calling method by simply improving the steps with illustrations, photos of the caller etc, in the same way however, it is a favorite address book where you can memorize and call the most called numbers immediately (up to 27 numbers) and you can associate a photo next to the person's name.
