This app is specially crafted the help senior citizens use their smart phone. Usually they only need a few apps, and that's exactly what this app offers. By default three apps are configured already, but you can change this to whatever app you need. The setup should ideally be done by someone who feels comfortable with smartphones already.
My grandfather uses the dialer, text messages, camera, photos, Whatsapp and the weather. The config screen easy accessible, but only on purpose, so no accidental changing of this app's settings.
For the best performance select Senior Homescreen as your launcher app. Press the home button of your phone after installing Senior Homescreen, and select 'Alwayse use' Senior Homescreen as your launcher application.
