Exactly what I was looking for! – Deleter Review

This app does one basic task that Apple doesn't let you do in Photos... bulk delete images that have not been marked as favorites. I already use PhotoSync to easily copy pics from my phone to my PC (great app!), but I hadn't deleted any of my old photos yet. Now I wanted to clean up the 10gb of photos that were taking up space on my phone. I had marked 600 of the >3000 pics as favorites, but iOS has no useful mass-selection tools so I was going to have to select every photo I wanted to delete manually. I have no idea why there's no "select all favorites" and "select all non-favorites", but this app took care of it instantly. I loaded the app, launched it and it immediately selected all 2,400 photos that I hadn't marked as favorites. I pressed delete (not nervously as I had backups on my PC thanks to PhotoSync), and a few seconds later the Deleter app had deleted 2,600 photos but left everything I had marked as a favorite untouched. Exactly what I was looking for. Even better was that when it deletes the photos, it actually moves them into the "Recently Deleted" folder in the Photos app, so you still have 30 days to move them back if you need to. Great app!!!!!!
