## What is MasterAlumb?

Turn tens of thousands of photos into the ones you actually want to keep.

After a few years your library is full of near-identical shots, saved screenshots, forgotten screen recordings and albums with nothing in them. Master Album finds them group by group, lines them up for comparison, and lets you clear the extras in a few taps.

【Finds what needs cleaning】
• Similar Photos — groups burst shots and near-identical photos, marks the best one to keep in each group, so you only confirm what goes
• Duplicates — exact copies grouped separately, so no extra copy is missed
• Screenshots — filter by All / Over 15 days / Over 30 days / Over 180 days / Over a year
• Videos — filter by All / Slo-mo / Time-lapse / Cinematic / Screen recordings to find the big ones
• Live Photos, Selfies and Portraits — clear out the usual clutter, one type at a time
• Spatial Photos and Spatial Videos — 3D captures grouped on their own
• Empty Albums — finds albums with no photos in them

【Two ways to organize】
• By Date — browse by year and month and start from your most recent photos
• By Album — work through the albums you already have

【You stay in control】
• Choose Keep or Delete for every photo, and undo a step if you change your mind
• Photos are removed from your library only after you confirm
• Deleted photos go to "Recently Deleted" in Photos and can be restored within 30 days
• Keep instead of deleting — move photos into an album or mark them as favorites

【Progress you can see】
• Progress: check your overall status from the home screen, plus a year-by-year breakdown
• Completion summary: how many files were organized and how much space was freed
• Haptic feedback, which you can turn off in Settings

【Processed on your device】
Recognition and comparison run locally on your iPhone. No photo uploads, no network required. Your photos never leave your device.

【Languages】
Simplified Chinese, English and Español, switchable in Settings.
