MonTri — Swipe Your Photos

Your camera roll holds 12,000 photos. Maybe more.
MonTri is the darkroom where you edit that down.

Swipe left to delete. Swipe right to keep. That's the whole gesture — Tinder, but for the frames you've been carrying around since 2019. No batch screens, no algorithm scoring your memories, no upsell wall after three taps. Just one image at a time, the way a contact sheet is read.

What MonTri does:

— Swipe-to-delete photo triage. One frame, one decision. Bin fills on the left, keepers on the right.
— Duplicate detection. Catches the seven near-identical shots from that one sunset.
— Blurry filter. Pulls out the misfocused frames you swore you'd revisit.
— Screenshot pile. Separates receipts, memes, and screen captures from your actual photos.
— Contact sheet review. Before you commit, see the whole roll laid out like a darkroom proof.
— Storage counter. Watch the gigabytes come back in real time.

MonTri is built for galleries between 5,000 and 20,000 photos — the kind that make iCloud charge you monthly. It is not an AI that decides which memories matter. You decide. The app just clears the table.

Your photos never leave your device — MonTri reads your gallery locally and never uploads a single frame to a server. No tracking.

Designed in a contact sheet aesthetic: cream paper, chinagraph red, the typography of a 1970s photography manual. A photo cleaner that respects the medium.

Made for the people who care about their gallery the way a film photographer cares about a roll. Photographers, designers, anyone whose phone storage warning has become a weekly event.

Keywords we believe in: swipe, declutter, camera roll, gallery, duplicates, blurry, storage, triage, contact sheet, darkroom.

Free. Premium removes the ads and unlocks the darkroom mode.
