"Sort My Photos" is an iPad/iPhone app that lets you arrange the photos in your albums in whatever order you want for viewing and for running in slideshows.
A standard way to import photo albums into your iPad is to select individual directories containing images from your desktop or laptop computer. Two common limitations with this method are that
you may not wish to display every image on your iPad and
the photos frequently are not displayed in the desired order when viewing or running in a slideshow.
"Sort My Photos" provides a simple user interface for addressing these problems.
Sorting the photos in an album into whatever order you desire;
Having the sorting order of a photo collection saved to the iOS system (i.e., the collection will be displayed in the same order in other apps such as "Photos");
Manual sorting of photos in an album via drag and drop in addition to a selection of quick sorts by creation date, last modification date, favorites, or media type;
Hiding any photos you don't want to display;
A choice of running a slideshow in a preselected order vs. a random order.
Other features include:
Image information display;
Creating new albums;
Adding photos to any album from any other album or from "Camera Roll"/"Saved Photos".
Update for iOS 9.
Bug Fix: scrolling problem that appeared with iOS 9.
Ratings and Reviews
No filename sort?
It appears there is no sort option for alphabetical by filename. Amazing. Am I the only one who still uses filename to organize photos?
Fills a hole in the default Photos app for sorting an individual album by date. The only quirk I have seen is it leaves a small white border around 4x3 photos, while 3x2 DSLR photos do that for a split second and fill the screen, while shifting a little bit above the center of the screen.
Also, it needs a delete function for albums where deleting is allowed (I don't think albums synced from iTunes allow deletes).
I was looking for an app that could order my photos in a desired sequence. Apple fails in this regard, so I turned to this app. It will not change the order of any album downloaded by iTunes. It allows you to create a slideshow where inside that feature you can order the pics. Clearly not what I anticipated. It turns out that the pics are sorted by date created with the oldest first. My opinion -- not worh the dollar.
With Family Sharing set up, up to six family members can use this app.
