Time
Every weekend afternoon
from last spring
Every default gallery is one endless reverse-chronological scroll; once a photo scrolls past, it's gone. SnapAtlas replaces it with eight precise filter dimensions. Combine them and a moment sharpens into focus.
- Year · month · day range · weekday · time of day — "2023 + May + Sat–Sun + Afternoon"
- Orientation · source · custom date range too
- Pinch-zoom grid; long-press multi-select to delete, share or collage
Place
"I know I shot it here"
— on the map
Photos with GPS information appear on Google Maps automatically. After a trip you'll find yourself naturally asking, "What did I shoot here?"
- Automatic clustering by zoom — fifty shots from one neighborhood become a single "50" pin
- Tap a pin and every photo from that spot spreads out as a grid
- Far more intuitive than naming folders by location
Auto Collage
The app picks the layout,
you keep the memories
The biggest friction in collage apps is deciding which photos go where. Select several and SnapAtlas groups them by date and generates multiple collages in one shot.
- Auto-grouping by date — day, month, year or weekday
- Automatic layout — 1–8 photos per grid, 1–4 grids per canvas
- Style — background, margin, corners, date and place labels, patterns
Library
Collages saved
as lightweight recipes
Each collage is saved as just the photo IDs and style parameters, so the library stays nimble. Open one later, tweak the background or roundness, and re-export.
- Sort by recent or name, rename the ones that matter
- Duplicate to try "same photos, different style"
- Multi-select to delete several at once
Export
Save to your gallery
or share right away
Finished collages save to your gallery as image files or share straight to messengers and social apps.
- Canvas 1080 px wide
- Height auto-fitted between 720 and 2160 px by photo count
- Sized for social uploads out of the box
Versus other apps
What makes SnapAtlas different
Versus default galleries (Google Photos, Samsung Gallery)
A flow tuned for recall
Default galleries show flat pins on a map. SnapAtlas uses a cluster → grid flow tuned for recall, with 8-dimensional filter combinations on top.
Versus collage apps (PicCollage, Canva, etc.)
Almost no decisions
Those make you hand-pick and hand-arrange. SnapAtlas turns one selection into many finished collages automatically.
Versus photo cleaners (Slidebox, etc.)
Rediscover, not delete
Cleaners focus on deleting clutter. SnapAtlas focuses on rediscovering the photos worth keeping.
