Customize your iPhone or iPad with Sci-Fi and Space wallpapers, Home Screen Image Widgets, and Clock/Date Widgets. INCLUDES: - 260+ square and rectangle Image Widget Backgrounds in many styles (or add your own images) - 130+ backgrounds or use a color gradient for the Clock/Date Widget - Icon packs in 13 styles with 2,000+ icons to set with the Shortcuts app - A large variety of wallpaper for Home / Lock screens to perfectly fit every size iPhone / iPad (Always adding more wallpaper, so check periodically) WIDGET DIRECTIONS Add a widget to your home screen in the usual way (long press the home screen and when in jiggly mode press the '+' on top. Scroll down to Sci-Fi Themes and select the size you want [do this for each size you want]). Long press the widget to change the theme from the images you set in the app. Some of the Sci-Fi styles are modeled after popular sci-fi shows and movies. The look like they should work, even with indecipherable meaning or function. And just like the props, iOS gives them the same functionality - NONE. It's parody how the sci-fi designers thought future displays would look while being impossible to use. *These are generic images. Please do not ask me in reviews or by mail to include any trademarked names, logos, images or other properties. I respect copyrights and will not include them. If used in tandem with my calculator widget, icon maker, widget maker, keyboard, and ringtones apps, you can really create a fuller theme.

Verdict
The clearest difference is price: LeetSpeech at Free against Sci's $3.99. Sci's advantage is chart position (#66 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
