 #### Note regarding iOS vs. Android
 *I wanted to submit this to the App Store (as a free app) because I have an account, but Apple won't allow just a clock app into the App Store, hence the "copy to clipboard" functionality. I don't currently have plans to build this into the Android version unless it's requested enough. Or, you know, fork and pull request it!*
