This App-widget allows you to call a contact directly from the home screen, simply by selecting it from a previously created list. This person can be contacted either by normal call or WhatsApp. In this case the WhatsApp app must already be installed and the person must already be present among the WhatsApp contacts. Using the configuration page you can increase or decrease both the image and text size to best fit your screen size.This feature can be useful for older people and/or people with vision problems. In fact, just prepare a list of the most called or useful people in case of emergency (preferably associated with a nice sharp photo) and they will be easily reachable (even via WhatsApp) without too many searches.
