SnapAtlas
SnapAtlas brings the thousands of photos buried in your gallery back to life — by time, by place, and by turning many shots into a single collage with one tap.
Your old photos shouldn't stay buried
The average phone holds thousands — sometimes tens of thousands — of photos. But every default gallery shows them as one endless reverse-chronological scroll. Once a photo scrolls past, it's gone for good.
- You want to see that trip from two springs ago, but you can't find it.
- You remember taking pictures at that place — but where are they?
- You'd love to turn a few shots into a single memory, but every collage app makes you pick them one by one.
- New photos pile up. Old ones drift further away every day.
SnapAtlas solves all three in one app — time-axis filtering, map-based recall, and automatic group collages.
Rediscover photos by time
The endless scroll is replaced with eight precise filter dimensions. Combine them and a specific moment sharpens into focus.
- Year — 2024 / 2023 / 2022 …
- Month — January through December
- Day-of-month range — 1–10 / 11–20 / 21–end
- Day of week — Monday through Sunday
- Time of day — Dawn / Morning / Noon / Afternoon / Evening / Night
- Orientation — Landscape / Portrait
- Source — Camera / Downloads / Screenshots, and more
- Custom date range — Pick your own start and end
One combination like "2023 + May + Sat–Sun + Afternoon" instantly surfaces every weekend-afternoon shot from last spring. A slice like "Sunday afternoon" simply doesn't exist in a default gallery.
Browse in a staggered grid with pinch-zoom to change density on the fly. Long-press to enter multi-select for delete, share, or send-to-collage actions.
Rediscover photos by place
Photos with GPS information appear automatically on Google Maps. Nearby shots cluster automatically based on zoom level — fifty photos from the same neighborhood become a single pin labeled "50".
Tap a cluster and every photo taken at that spot spreads out as a grid. It's far more intuitive than naming folders by location, and after a trip you'll find yourself naturally asking, "What did I shoot here?"
One tap to bundle memories — Auto Collage
The biggest friction in collage apps is that you have to decide which photos go where. SnapAtlas removes that decision.
- Select several photos from your gallery.
- The app auto-groups them by date (day, month, year, or weekday — your choice).
- Each group gets an automatic layout — 1–8 photos per grid, 1–4 grids per canvas.
- Swipe through the previews — multiple collages, generated in one shot.
Style every aspect to taste:
- Background color — White / Black / Gray / Beige / Sky / Charcoal (6 presets)
- Margin — Cell spacing from 0 to 40 px
- Rounded corners — 0 to 50 px
- Date labels — Show / hide, with a choice of four corner positions
- Place labels — Auto-shown when entering from a map cluster
- Decorative patterns — Add a background pattern with 4 density × 4 rotation steps
Collage Library
Every collage you create is saved as a lightweight recipe — just the photo IDs and style parameters, so the library stays nimble no matter how many you keep. Inside the library you can:
- Sort by recent or name at a glance
- Rename the ones that matter to bring them up top
- Duplicate to try "same photos, different style" in seconds
- Multi-select to delete several at once
Open a saved collage later, tweak the background or roundness, and re-export — no need to start over.
Export and share
Finished collages can be saved to your gallery as image files or shared instantly to messengers, social apps, and more. Canvases are 1080 px wide with height auto-fitted between 720 and 2160 px depending on the number of photos — sized for social uploads out of the box.
What makes SnapAtlas different
- Versus default galleries (Google Photos, Samsung Gallery) — Default galleries show photos as flat pins on a map. SnapAtlas uses a cluster → grid view flow tuned for recall, with 8-dimensional filter combinations on top.
- Versus other collage apps (PicCollage, Canva, etc.) — Those make you hand-pick and hand-arrange. SnapAtlas turns one selection into many finished collages automatically.
- Versus photo-cleaner apps (Slidebox, etc.) — Cleaners focus on deleting clutter. SnapAtlas focuses on rediscovering the photos worth keeping.
Privacy — straight talk
- Your photos stay on your device. No cloud uploads.
- No account, no sign-in. Open the app and you're in.
- Location data (photo EXIF and your current location) is processed locally for map features only.
- Ads disclosure: SnapAtlas is free to use and includes Google AdMob banner ads. The AdMob SDK sends your advertising ID and impression/click events to Google.
