With the holidays coming up you may be taking photos for posting to Facebook, Twitter, and other social media outlets. If you want to make certain those photos don't contain location data before putting them on the Internet, you'll need an app to scrub the metadata out. I've been using Metapho for this purpose. The app is easy enough to use. Select an existing photo and push the big red button to remove the metadata. The app is free but the metadata removal tool is currently a $2 in-app purchase.
