ViewOne vs PhotoSweeper
PhotoSweeper is the go-to Mac app for finding and removing duplicate photos across an entire library. It is mature, fast, and very good at what it does. ViewOne is built for an adjacent but distinct job: reviewing a fresh folder of burst photos and picking the keeper from each group. Here is when each tool is the right answer.
Dimension-by-dimension
| Dimension | ViewOne | PhotoSweeper | Edge |
|---|---|---|---|
| Primary job | Burst-group review. Pick one keeper from each group of similar shots taken seconds apart. | Library-wide duplicate detection. Find and remove byte-identical or visually similar copies scattered across an entire Photos library or set of folders. | |
| Burst detection | Automatic. Groups frames by capture time and filename pattern the moment the folder loads. | Not a burst-specific feature. PhotoSweeper finds similar images, but does not group a 12-frame burst as a single decision point. | |
| AI quality assessment | On-device Vision framework scores sharpness, exposure, and faces to suggest the best keeper. Pro feature. | Comparison is based on file metadata, perceptual hash, bitmap similarity, and resolution. No AI assessment of which photo is qualitatively better. | |
| Duplicate detection across a whole library | Not the use case. ViewOne is a folder-scoped review tool. | First-class. Scan a Photos library plus several folders at once, find every duplicate, choose which copy to keep with full control. | |
| RAW + JPEG pairing | Automatic. Rejecting a JPEG with a same-name RAW sibling moves the RAW too, with a +RAW badge before commit. | Detects RAW + JPEG pairs and treats them as related, with rules for which side to prefer when removing duplicates. | |
| Workflow | Keyboard-first review. P / X / V / Cmd-B for pick, reject, compare, accept AI. No catalog or import step. | Scan, review the matched groups, mark for removal, commit. More steps but more power over the whole library. | |
| Pricing | Free tier for manual burst review. Pro at $1.99/month, $12.99/year, or $29.99 lifetime. | $9.99 one-time for PhotoSweeper, $19.99 for PhotoSweeper 3 Pro. Excellent value for what it does. | |
| Privacy and architecture | 100% local, Vision framework on-device, no network access. | Local Mac app, no cloud upload, mature privacy posture. |
ViewOne advantage · PhotoSweeper advantage · roughly equal
Where ViewOne wins
- Burst-first workflow is a different mental model from library duplicate hunting. If your task is "I just airdropped 200 burst photos and need to keep the good ones," ViewOne is built for that exact loop.
- AI Best Pick scoring flags the sharpest frame using on-device Vision. PhotoSweeper does not try to tell you which photo is qualitatively better, only which ones are similar.
- Keyboard-first review with single-key pick, reject, compare, and accept-AI shortcuts. Designed for cutting through 500 frames without your hand leaving the keyboard.
Where PhotoSweeper wins
- Library-wide deduplication is what PhotoSweeper was built for, and it does it better than anything else on the Mac. ViewOne does not try to scan your whole Photos library for duplicates.
- Mature feature set with years of refinement on edge cases — Live Photos, HEIC + JPEG pairs, similar-but-not-identical detection, library merging.
- Cheaper if you only need duplicate detection. $9.99 one-time covers the full PhotoSweeper feature set without an upgrade path.
