The camera that overlays your last photo

An opacity slider, not a fixed overlay

Drag the ghost anywhere from 0 to 100%. Most people land around 30–40% for everyday shots — enough to see edges and landmarks from the last photo without losing the live feed underneath it. Push it higher, toward 60–70%, when the background is busy or dim and a faint overlay would just disappear, like a cluttered garage or a shaded backyard corner. Pull it down near 10–15% in bright, high-contrast rooms where a strong ghost image would wash out what the camera's actually seeing right now. It's a slider, not a fixed setting, because no two rooms or bodies need the same amount of guide.

Auto capture and an alignment score

As you move, SameShot compares key points between the ghost image and the live frame — shoulders, hips, a wall corner, whatever's stable in the shot — and shows a running alignment score instead of leaving you to eyeball it. Once that score crosses your threshold, auto capture fires the shutter on its own, which matters most when the phone's propped on a shelf or tripod and you can't also reach the screen. For the manual side of this — tape marks, tripod height, picking a light source you can repeat — see our guide onaligning progress photos.

Everything after you tap the shutter

Once a photo's saved to a project, SameShot builds a before/after slider automatically, so you can drag between the first and latest shot without opening an editor. Pick any two photos in the project and it'll do the same for that pair. When you've got enough frames, export a timelapse reel in 9:16, ready for Stories, Reels, or TikTok without a separate video app. If you'd rather stack and compare photos by hand first, ourguide to overlaying photos covers the free-editor route too.

FAQ

What is a photo overlay camera app?

It's a camera that shows your previous photo as a semi-transparent layer over the live viewfinder, instead of just showing you what the lens sees right now. You move the phone and yourself until the live frame lines up with the ghost image underneath, then shoot. It solves the problem of repeat photography — fitness progress, room renovations, garden growth — where the whole point is that two photos taken weeks apart need to match in angle, distance, and framing.

Does the overlay appear in the final photo?

No. The ghost image is a guide shown only on screen while you're lining up the shot — it disappears the moment you tap the shutter. The photo that actually saves is a clean, normal capture from your camera, with no ghosting, watermark, or second image baked in.

Is SameShot free?

Yes, SameShot is free on Google Play. The Android app is in testing now, with access available through this site, and the iOS version is in development.
