iOS: You have a few great options for launchers on iOS, but LaunchCode takes a different approach by integrating the standard Notification Launcher with a fun gesture system.
At its simplest, you can use LaunchCode to launch apps and actions directly from the Notification Center, just like you can with an app like Launch Center Pro. Beyond that though, you can also set up a ton of custom gestures to launch apps and actions as well. Just select the app you want in LaunchCode, draw a gesture, and you can launch it from the app at any time. It's a bit silly, but it's a fun way to move around your apps. The free version has ads, but it's a good way to decide if you're interested in the full version.
