I tried cleaning up my iPhone by getting rid of the silly named folders (when you plug it into your computer and browse DCIM) and ended up screwing the Camera Roll up. I tried countless software to get my photos back into Camera Roll instead of a different folder in Photos and finally found this app. This app did wonders and put everything back where it was supposed to and all my photos are back in Camera Roll. Make sure if you want to keep the timeline of your photos the same, click the cog in the top left and enable "Ordered Transfer: by date" and it will put everything back perfectly. Absolutely worth the $2 to fix my photos.
