Add some Sci-Fi to your Home Screen. This widget making tool is for displaying many types of information with great styling customization. You can display multiple widgets, all with their own unique style and info in Large, Medium, and Small widget sizes You can change the layout, background, fonts and colors, and even use your own images. *Offline contains the pre-made template backgrounds, but the background selection section needs internet to download from online. DISPLAYABLE INFORMATION: • Digital clock • Analog clock (some with second hand to show a little animation) • Calendar • Date/Day • System info (battery, brightness, memory, storage) • Countdown/Days since • Step count - Distance - Floors • Display contacts (just opens this widget app) These are generic sci-fi styles to to keep the coolness of how designers imagined future interfaces past and present on low and high budgets, but actual display real information instead of meaningless gobbledygook. * Please do not ask in reviews or by mail to include any trademarked names, logos, images or other properties.
