A feed made of your own life
MemoryScroll replays your camera roll as a full-screen, swipeable feed — the format you already lose hours to, pointed at the ten thousand photos and videos you took and never looked at again.
It isn't a replacement for your Photos app. It's a replacement for the app you open when you're bored.
The mission
Nobody deletes the app and simply stops. The reach for the phone is automatic, and if there's nothing there, the old app comes back. So MemoryScroll doesn't ask you to scroll less. It gives the reflex somewhere better to land.
Photos is already good at albums, search and storage, and MemoryScroll doesn't try to be. It never moves, edits or re-organises a single thing in your library. It's a different way to look, not a different place to keep.
The same vertical swipe, the same easy autoplay — except every clip is one you were actually there for. You come away having remembered something instead of having consumed something.
The science
The gesture is identical. What it does inside your head is not. Doomscrolling runs on the anticipation of a reward that never quite arrives, kept alive by a threat-detection system that never gets to stand down. Recognising your own memory does something close to the reverse.
A variable-reward loop layered on top of an ancient threat scan. The brain stays switched on, waiting.
Released in anticipation of the next swipe, not on arrival at anything good — the same variable-reward schedule a slot machine runs on.
Alarming headlines wake the amygdala, and it keeps dumping cortisol into your system long after you've put the phone down.
A fight-or-flight response with nothing to fight and nowhere to run. You stay on high alert, scanning for the next threat.
Recognition is a reward that actually lands — and it brings the stress system down with it.
The moment you recognise a face or a good day, the ventral striatum and VTA light up — an actual hit of pleasure, not another promise of one.
Family, old friends, a pet that's gone. Oxytocin is the warmth you feel in your chest, and it cuts loneliness rather than feeding it.
Reliving a positive memory steadies mood and buffers whatever is stressing you today.
Your memory centres and prefrontal cortex work together to turn the amygdala down. The exact system doomscrolling keeps switched on.

MemoryScroll is not a medical device and makes no therapeutic claim. The
research above describes how brains generally respond to threat-scanning and
to autobiographical memory; it is the reasoning behind the design, not a
promise about your results.
The app
The average camera roll is tens of thousands of items deep, sorted newest first, and functionally ends about two weeks back. Everything below that is yours and invisible. MemoryScroll is the machinery for getting at it.
The feed
Full-screen, autoplaying, endless — and drawn entirely from your own library. Hold either edge for 2× the way you already do elsewhere. Like it, save it, share it, or bin it without leaving the feed.
Filters
Pick a category, a year, a month, a season — or ask for everywhere you've been that isn't home. The whole library narrows to it, and the feed keeps rolling.
What's actually yours
A camera roll is half memories and half saved memes, screenshots and reposts. MemoryScroll estimates where each item came from and lets you keep the feed to the things you actually shot.
Your phone groups photos by time and place and calls it a memory. Memory Lane looks at what's actually in them — thirty photos, a crowd of faces and a sky full of fireworks isn't "July 4th", it's a night you'd want back. Events are grouped by what happened rather than only when, named for their subject, and ordinary days at home stay out of it.
The opposite of posting. When you turn something up worth sending, it goes to a handful of named people — family, the friends who were in it — and nobody else but our moderation team, who can view anything that's sent to keep it safe. A small circle you choose, not an audience. No followers, no like counts, nothing to perform for.
Privacy
Scrolling, filtering and recognition all happen on your phone, and nothing in your library is uploaded unless you choose to post or send it. Videos you don't post or send stay on your device, and no one else can view them. If you do post or send something, it is uploaded, and our moderation team can view it to keep MemoryScroll safe.
All recognition runs through Apple's own Vision framework, on your phone. Your library is never uploaded; only what you choose to post or send is.
Browsing your own feed needs no account, and the app isn't measuring how long you stayed. An account is only needed for the Capture Circle. Apart from the Capture Circle, the only thing it talks to is a music account, if you choose to connect one.
MemoryScroll reads. It doesn't reorganise, re-encode, back up, or move anything. Delete the app and your camera roll is exactly as it was.
You just haven't scrolled it since the day you shot it.
