iOS/Mac: Transloader is an app that allows you to send a download URL from your iPhone to your Mac. If you regularly queue up files for download on the go, it's a utility that can save you a lot of time.
Simply paste the URL of a file you want to download on your Mac into the iPhone app, and it sends the info over and starts downloading right away. You need to have iCloud file-sharing enabled on your iPhone (Settings > iCloud > Documents and Data) for it to work. Once you're set up, paste as many URLs into the iPhone app as you like, and the next time you open Transloader on your Mac, they'll start downloading automatically. Transloader isn't the only option out there, but it works well as a simple solution that uses iCloud instead of another service.
