iDosos is a free Android application developed by Patrick Farias, designed specifically for senior citizens. It provides tutorials on how to use basic smartphone functions such as making and answering calls, reading and writing messages, adding and calling contacts, and setting alarms.

The app features emojis that assist users in all activities, showing them how to perform tasks and repeating instructions as many times as needed. Moreover, all instructions are accompanied by audio narration, making it easier for users to follow along.

The buttons and functions are designed to prevent accidental touches, and the emojis are always available to help users in case of any issues. With iDosos, seniors can easily adapt to new touch screen devices and show their family members the new functions they have learned after each tutorial.
