The next app on my list is Pixlromatic.  This has become one of my favorites.  You can either take a photo with the app or upload a saved one.  When you upload a pic from the gallery it is a little slow, just touch the picture and wait a couple seconds and it will open.  It starts with a choice of filters (the film icon), all of which are named after people.  There are effects (the light bulb) you can add to your photo like light leeks and scratches and the last option is a choice of frames.  It is simple and fast to use, it has become one of my go to apps when I want to edit a pic to upload to instagram or share on facebook.  I think this was a free app with a good selection of filters and effects.  If you want more you can click on the film canister icon on the upper right and purchase new sets.  I recommend this app if you are looking for a free, fun and fast way to edit photos.
