리뷰가 말하는 불만
경쟁앱 리뷰 90개에서 추출
- “It only identified 1 single duplicate photo, out of numerous duplicates on my phone.”
- “I have dozens of known duplicate photos but the app located 0 after several scans.”
- “Over 46,000 photos and NO DUPLICATES WERE FOUND, something's not right.”
- “The algorithm misses almost all of the similar photos in my 12,000 photo db.”
- “I edit photos over and over with tiny changes and it found none of them.”
Detection that actually catches near-dupes including crops and re-edits, using on-device perceptual hashing plus Vision feature prints, and shows an honest count of what it found versus what it skipped.
- “Every time I come back to it, it starts all over again or is on the start scan page.”
- “It stalls. Doesn't scan. Must be the only app running and in the foreground.”
- “If the screen goes off the app stops indexing. I re-started the process at least 10 times, simply doesn't finish ever.”
- “I waited for it to scan all my photos, nothing happened, and when I opened it again it started the scanning from the start again.”
Resumable, checkpointed scanning that survives backgrounding and picks up where it left off, with honest messaging about iOS background limits instead of a false scans in the background promise.
- “Similar, aren't even close.”
- “The algorithm sometimes is off, grouping photos taken on the same day and location but with quite different subjects.”
- “The images that are flagged as similar are nothing like each other.”
- “Too many of my photos came up grouped as similar that were nowhere near, a bunch of receipts and one real photo of someone.”
Separate exact duplicates from looks-similar, with a tunable threshold defaulted conservative so groups stay tight and people trust what the app puts together.
- “At approximately 20,000 it pretended it was still working but it wasn't.”
- “It freezes after it scans about 42,000 and although it says it's still scanning the numbers aren't moving.”
- “The app tends to freeze around 100,000 photos.”
- “After several attempts, it always stops about halfway through.”
Stream-process the library in bounded batches so 50k to 100k+ libraries finish without freezing the UI, with real progress and a clean resume after any crash.
- “Previewing photos not working.”
- “Doesn't allow you to see clearly, just shows a blur you are supposed to decide on.”
- “I can't look at the preview images. They are always blank.”
- “Some showed their size and looked alike but then would come blank with 0 size.”
Always render sharp real thumbnails in the compare view and load full-res on tap, so people can confidently pick which copy to keep before anything is deleted.
1인이 만들 수 있나
개발 난이도와 리스크를 분해
A focused on-device duplicate and similar photo cleaner is buildable solo in about a month using PhotoKit plus Vision feature prints, with no server, which doubles as a privacy selling point. The hard parts are detection accuracy and not freezing on huge libraries, both solvable with batched processing, but they are exactly where every existing app fails.
만든다면, 이렇게
1페이지 기획서 (출발점, 정답 아님)
An on-device photo cleaner that actually finds the duplicates and near-dupes other apps miss, with sharp side-by-side previews so you delete with confidence.
iPhone owners with thousands of photos who want to reclaim storage by clearing duplicates and near-identical shots, and who don't trust apps that miss most of them.
Existing apps either miss most real duplicates, group unrelated photos as similar, stall or restart their scans, freeze on big libraries, or show blank previews, so people can't trust them to clean safely.
- ·On-device detection that catches exact duplicates and near-dupes like crops and re-edits, using perceptual hashing plus Vision feature prints
- ·Side-by-side compare view with sharp real thumbnails so people can see exactly what they're deleting before confirming
- ·Resumable, checkpointed scan that survives backgrounding and shows honest progress, X of Y scanned and N found, instead of restarting from zero
- ✕True background scanning promises you can't keep on iOS
- ✕Bundling unrelated cleaner features like contacts, storage, or a secret vault that bloat the app and distract from getting detection right
Scan for exact duplicates only, group them with real thumbnails, and let the user multi-select and delete through PhotoKit. Get that flawless and fast on a 20k-photo library before adding fuzzy similarity.
Free scan and preview, with a one-time unlock or low-cost option for bulk delete and similarity tuning. Reviewers here openly prize apps that are truly free with no fake trial, so be upfront about the paywall and never hide the basic scan behind a trick trial.
솔직한 경고
이 기회의 가장 큰 함정
The keyword is led by free apps including a 666k-review giant and reviewers openly prize truly free, so your only real wedge is detection that catches the near-dupes everyone else misses, which is also the single hardest thing to build.
