By far the best, but needs some bug fixes

Update: the iOS 10 update has made this app a lot less useful. I can no longer download photos from the browser into the app archive, because a native iOS 10 screen comes up first, offering to share or download the image to my camera roll, and that blocks the apps built-in download option. So for now, I can only give 2 stars. Fix the iOS 10 bug and Ill move it up to 5.

Ive tried over a dozen similar apps, and this one is leaps and bounds better than any of the others. Most of them dont encrypt your images/videos, so anyone who plugs in your phone could access them. The ones that do encrypt are very clumsy.
