Keepmemory

Keepmemory frees up iPhone storage without deleting a single photo. WHAT MAKES IT DIFFERENT Every Live Photo you take is really two files: the picture, plus a 3-second video clip. That clip is often larger than the photo itself. Keepmemory strips out just the video and keeps the still — same resolution, same date, same location, same albums. Nothing is cropped, recompressed, or lost. Most cleaners only offer to delete. Keepmemory starts by giving you space back for free. THEN CLEAN THE REST, YOUR WAY • Screenshots — swipe right to keep, left to remove • Similar shots — burst and rapid-fire photos grouped together, tap to pick which ones stay • Blurry photos — sorted worst-first so the obvious ones come up first • Large videos — listed by size, biggest first NOTHING IS DELETED BEHIND YOUR BACK Photos you swipe left go to a review queue. You see them all together before anything happens, and you can pull any of them back out. Deletion happens once, at your confirmation, and everything lands in Recently Deleted for 30 days. Favorites, edited photos, and anything from the last 30 days are skipped automatically. PRIVATE BY DESIGN No account. No upload. No server. Your photos never leave your iPhone. Keepmemory reads your library on-device and that is all. PRO — ONE TIME, NO SUBSCRIPTION Free: sort 100 photos a day, extend with an optional ad. Pro: unlimited sorting, no ads, one single purchase. No auto-renewal, ever.

Verdict
The clearest difference is ads: HTML Viewer at none against Keepmemory's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.
