Small sessions.
Real momentum.

The app is kind of addictive - I didn’t notice I’d spent an hour in it. It brought back great memories from random periods of my life. I love the raccoon, and the achievements are fun.

I tried about ten photo organizer apps, and nothing worked for me besides this one. No AI can tell me which picture is important to me and which is not - that’s personal, and I want to decide.

I finally made progress without feeling overwhelmed. It was a better use of two minutes than doom scrolling.

A few questions.
A clearer picture.

Get to know Lumenist before your first review.

How is Lumenist different from Apple Photos?

Lumenist gives you a place to start when your photo library feels overwhelming. Review one day at a time, compare similar shots side by side, and keep track of the days you’ve already handled.

Where do I start if I have thousands of photos?

Start with a Quick Win. Lumenist opens an unreviewed day with fewer photos, so you can make progress in a short session. Choose a Cozy Review or Deep Dive when you have more time.

Does Lumenist delete photos automatically?

No. You decide what to keep and what to delete. Lumenist groups similar photos and can offer clues like smiles or blur, but it never makes the decision for you. You can keep every photo and still mark a day reviewed.

Can I compare similar photos before choosing what to keep?

Yes. Open two photos side by side, then pan or zoom both at once to compare expressions and small details. You choose the shot that matters to you.

Can I organize photos into albums?

Yes. You can favorite photos and add them to albums while reviewing a day. It’s a way to organize the moments you love as you find them.

Do I have to finish a whole day in one sitting?

No. You can stop halfway or skip a day. A day only leaves your review queue when you mark it complete, and completed days stay in your history so you can see your progress.

Does Lumenist upload my photos?

Lumenist processes your photos on your iPhone and does not upload them to its servers. Limited account information and usage statistics are handled separately, as explained in our privacy policy. Read our privacy policy.

Is Lumenist free?

Lumenist is free to try. A subscription is required for unlimited use. You can review the available subscription options and pricing in the app before subscribing.
