Purrge vs Fliff

Delete photos fast. Really, really fast. CNET: "... delete photos faster, with less tedious tapping and more swiping." The Next Web: "Purrge lets you swipe (in feline fashion) ... to quickly delete rejects." iDownloadBlog: "If your main focus is on deleting mass quantities of photos with a swipe, this is perfect for you." AppAdvice: "... purge unwanted items from your photo library using simple swipe gestures." iPhone Photography School: "... delete unwanted photos with cat-like reaction speed..." Matts Apps: "... incredibly simple design... I really can't believe I haven't found an app like this before." @thejaketrease "This is possibly my most-used app now." @eevonvon "This app speaks to me on so many levels..." @LisaSullivan "YES" @yeesamson "Simple and beautifully done. Delete unwanted photos from your iPhone, save space and time." @MDJCreative "Purrge is a great app for clearing out your burgeoning iPhone camera feed." @ccarella "... I love this idea for a mobile camera roll utility." @PleaseEnjoy "The annoyance of deleting iPhone photos 1 by 1 has been solved by this awesome app..." @mitchellholder "Have always wanted this..." @nicolejensen "Finally!" Purrge is a beautifully designed app for staying on top of your ever growing photo library. The app takes full advantage of simple swipe, drag, and flick gestures to make deleting pictures easy, fast, and (dare we say) enjoyable. Grid View: Select photos one at a time or select multiple photos at once by swiping across. Single Photo View: Swipe up to delete. Swipe back and forth between photos to determine which photos you want to purge from your library. Shake to undo! Today View Widget: Keep an eye on your photo count when you're not using the app. Simplify photo management, delete photos lightning fast, get rid of screenshots, duplicates, and bad photos, and free up memory on your iPhone and iPad. You can kiss (or hiss) these errors goodbye: "Cannot Take Video" "Cannot Take Photo" "Not Enough Storage" "Storage Almost Full" Photo hoarders rejoice! /\__ /\ (=^_^=) Meow at us @purrgeapp on Twitter. Enjoy!

With Fliff you can convert formats of image files or scale them. You can load images from the clipboard, the Photos app, the Files app or from the camera. The converted images files can be saved to file system and to the camera roll and can be copied to the clipboard or shared. You can preview them in order to check the file size and the quality, espicially when using compression. Fliff can also be called from the Share menu in other apps that provide images. Furthermore Fliff is also a photo editing extension, i.e. you can use it as a plugin in the edit mode of the Photos app.
