TripMode is an app that prevents data usage while tethered to mobile hotspot

TripMode seems like a great way to save on unnecessary data usage while traveling and tethered to a mobile hotspot that doesn't have unlimited internet access. After all, if those giant Dropbox files aren't critical to your workflow, why have your computer download them while you're already limited to traveling internet access? Saves money!

The app is available for Windows and Mac and costs $7.99.
