Large Launcher Senior Phone
Large Launcher Senior Phone is a well-balanced and totally free senior-friendly launcher. The home screen layout may be busier than other options, but it includes everything a senior needs within hand's reach: favorite contacts, date and hour, weather widget, phone, message, camera, SOS, gallery, and settings.
In addition, it comes with a preset "flashlight" widget that turns on the rear camera to provide a handy torch. Setup is easy, it's highly customizable, and it even includes some themes.
