Cam for Android is already a good app, but I believe there are a few minor improvements to make that would bring it closer to being a great app.
1) On the Library screen, when I scroll to the very top and tap the + button to import photos into my VSCO Cam library, the dialogue box that is opened requires me to choose an image viewing app every time. I think most users only use one image viewer. Android supports choosing a default app when that button is tapped, as detailed at http://developer.android.com/training/basics/intents/sending.html#AppChooser
. Even though this dialogue would allow a user to choose a default app, they also have the option of not doing so, which would preserve your current functionality instead of replacing it, keeping (maybe?) everyone happy!
2) When viewing my Library, I'd like to have the option to sort my Library by the date the image was taken, which I believe is preserved in an image's EXIF data. This would be a wonderful way to sort through my VSCO Cam library to off to friends.
An option to export my selected images, preserving the image's EXIF date taken and/or created data, and ignoring preexisting images in the export directory (based on file name, since this directory only contains VSCO Cam images), would be an excellent alternative.
3) When I slide out the navigation menu on the left, the circle of dots that signifies a menu does not mean a menu in any other Android app. A hamburger icon, as floats on the Library currently, would be much more intuitive, as this is what the majority of Android (okay, Google and a lot of other) apps now use.
4) When previewing filters on a photo, swiping left or right on an image would be a fun, fast way to switch filters, as opposed to the current "drudgery" of tap... tap... tap... swipe the tiny list to the next set... tap... tap... tap... swipe the the tiny list to the next set... etc.
