About PhotoSlimmer and newmean.ai

PhotoSlimmer is a photo cleaner for iPhone and Android that finds duplicate, similar, blurry, and closed-eye photos so you can delete them and free up storage. This page lists who makes it, how it works, and the facts we can stand behind, one per line.

Who makes this

PhotoSlimmer is made by newmean.ai (뉴민에이아이), a two-person software company in Incheon, South Korea, run by co-founders Hoonjae Lee and Yejin Kim. Hoonjae Lee builds PhotoSlimmer.
newmean.ai was founded in December 2025. PhotoSlimmer launched on the App Store on 4 June 2026.
The Android version launched on Google Play on 11 October 2026.
There is no marketing team and no outside investors. Questions go to [email protected] and are answered by the developer.

What it does

PhotoSlimmer finds duplicate, similar and blurry photos on your phone.
It finds exact copies of the same photo, such as a photo saved twice or saved again after receiving it in a messaging app, and shows them as “Exact copies” in Similar Photos, even when the dates differ. Nothing is deleted automatically.
The “Eyes closed” category finds photos with closed eyes.
It groups candidates and shows the photos taken shortly before and after, so you can compare before deciding.
You confirm which photos to delete. PhotoSlimmer never deletes anything on its own and never pre-selects photos for deletion.
Every deletion goes through the system confirmation. On iPhone, deleted photos move to the Recently Deleted album. On Android, they move to the system trash. Either way they stay there for 30 days.

Why it works this way

All analysis runs on your phone using an AI model built into the app. The model is derived from Meta’s DINOv3 vision model and runs on device, with Core ML on iPhone and LiteRT on Android. Its license is shown in the app under Settings, About, Open Source Licenses.
The Android version has no internet permission at all, so it cannot send anything anywhere. Google Play purchases are handled by the Play Store app.
In the App Store version nothing is sent to a server, because there is no server.
The App Store version of PhotoSlimmer makes zero network requests during photo scans. Its only network activity is Apple’s own App Store purchase flow.
Photos, thumbnails and embeddings stay on your device.
There is no account, no login, and no analytics, advertising or tracking SDK. The Android version includes only Google’s Play billing library and on-device AI runtimes (LiteRT, plus Qualcomm’s AI runtime to use the NPU on Snapdragon phones), and none of them can reach the network. The App Store privacy label reads “Data Not Collected”. TestFlight test builds contain no data collection code either. See the Privacy Policy.
The free version scans and reviews without limit and lets you delete up to 50 photos a day. The limit resets at midnight, local time.
A single one-time purchase removes the daily limit. Nothing else is locked behind it. There is no subscription and there are no ads.
We meter deletions rather than hide results because we would rather you see everything the app found and decide the pace yourself.

How detection works

The built-in model looks at each photo once and scores it for problems such as blur and closed eyes. It also produces a compact description of each photo that is used to group similar shots.
Similar photos are grouped by when they were taken and how alike they look, so a burst or a series of retakes ends up in one group.
You can choose how strict detection is, from a setting that lists a photo only when the model is confident to one that lists anything slightly off.
It finds closed-eye and blurry photos so you can delete them. It does not repair photos or open eyes.
We have not published a detection accuracy number, because we do not yet have an independent benchmark. It will miss some photos and list some that look fine to you. Candidates are suggestions, and you review them.

Not to be confused with

PhotoSlimmer is not a body or face slimming photo editor. It does not edit photos at all.
It is not related to an older open source project of the same name on SourceForge.
