duplicate photo cleaner

수요 읽기
두 모델이 독립적으로 평가 (측정 아님, 애널리스트 의견)
Opus와 Codex 두 AI의 읽기입니다. 측정된 수요가 아니라 판단이에요. 둘이 갈리면 그만큼 불확실하다는 뜻입니다.

리뷰가 말하는 불만
경쟁앱 리뷰 74개에서 추출
- “In one case there were five duplicates, but I was horrified to find they were five very different photos.”
- “Accuracy level 20% at best. Most of the pictures it picks as duplicate are not even close, like a bus and a picture of my nephew”
- “It will show 2 photos that are not at all duplicates.”
- “it is also had a lot of random photos in there that were not duplicates”
Conservative, on-device exact-duplicate matching first (same file hash/size/PERCEPTUAL near-match), with a strictness slider and a review screen showing metadata so users can verify before deleting.
- “App in the store says it is free, no advertising, no paywall. All of this is false.”
- “it's $9.99 a month. Scammers”
- “then it tries to make you purchase the pro version. Then more ads.”
- “every step has lots of advertisements”
Be upfront: unlimited duplicate deletion actually free, monetize via optional power features (bulk rules, video dedupe) with a clear one-time price, not a subscription trap.
- “This app merge all of my contacts into one!!!! I have no clue how to undo it”
- “I selected to merge and all my contacts are gone! 1600 of them!!!”
- “My photos have all been relabeled as Today. All are out of order”
Ship only photo dedupe at first, skip contacts entirely. Always delete to the system Recently Deleted album so recovery is native, plus an in-app undo queue.
- “agonizingly slow”
- “Continues to crash after scanning photos several times”
- “this app tells me it's all 'other'. None of it is pictures. And that I have no duplicates.”
Use PhotoKit change tracking and incremental background scanning with a progress bar; test on 200GB+ libraries before launch.
- “requiring you to manually deselect them (and this is very tedious)”
- “I wish it would show how far I was in selecting photos”
- “the selection dots are very small”
- “would give a clearer view of the pix, and allow for bigger selection dots”
Swipe-to-keep/delete per group (Swipewipe style), 3-across thumbnails, progress indicator, smart default that keeps highest resolution version.
1인이 만들 수 있나
개발 난이도와 리스크를 분해
A solo dev can ship a credible exact-duplicate photo cleaner in a month using PhotoKit and PHAssetModificationDate/file size/hash comparison, all on device. The catch is not code, it is distribution: 24 results, top app has 693k reviews, competition is rated high. You win on trust and honesty, not features.
만든다면, 이렇게
1페이지 기획서 (출발점, 정답 아님)
An honest, on-device duplicate photo cleaner that only flags true duplicates and never touches anything else.
iPhone owners with full camera rolls who tried a big cleaner app, got burned by fake matches or a surprise subscription, and want one safe pass to reclaim space.
Existing cleaners mislabel dissimilar photos as duplicates, mix in 'similar' results without asking, hide paywalls behind 'Free', and some damage contacts or photo ordering. Users end up manually re-checking everything or deleting the app.
- ·Contact merging or cleaning
- ·'Similar photo' suggestions mixed into duplicate results by default
- ·Storage stats screens that guess wrong ('all other')
- ·Subscription paywall on core deletion
Scan library, group exact duplicates, let user swipe to confirm, delete via PhotoKit. Nothing else.
Core duplicate deletion free forever. One-time unlock (~$4.99) for extras: burst detection rules, video dedupe, saved ignore lists. No subscription, no ads.
솔직한 경고
이 기회의 가장 큰 함정
The trap here is a fake-free paywall arms race plus 700k-review incumbents: you can build the app in a month, but users only trust this category after being burned, so any hint of ads-before-function kills you.
