ScratchStack: Photo Layers

iamprovidence

About this app

ScratchStack turns your photos into a scratch card. Stack two or more pictures as layers, then rub away the top one with your finger to reveal the photo underneath.

Show a before and after, a day turning into night, a room before and after a makeover, or hide a surprise for someone to uncover. Every stroke is saved, so you can come back and keep scratching any time.

STACK AND SCRATCH
• Pick any photos from your gallery and they become layers
• Erase the top layer with your finger, using an adjustable brush
• Undo and redo every stroke
• Reset a single layer or the whole stack
• Add, delete and drag layers to reorder them

ANIMATION
• Turn your scratching into an animation that replays it step by step
• Reorder, hide or show individual steps
• Adjust the speed and preview it live
• Scratches are drawn progressively, just like you made them

EXPORT
• Save the result as a PNG or JPG image
• Save the animation as an MP4 video or a looping GIF
• Choose the size and background color
• Files are saved straight to your gallery

FIND STACKS
• Let ScratchStack look through your gallery for similar photos taken around the same time, such as bursts, retakes or before-and-after shots
• Results appear while the scan is running, with layers already in order
• Create a stack with a single tap
• Completely optional, and it only runs when you ask

PRIVATE BY DESIGN
• No account, no ads, no tracking
• The app has no internet access: your photos never leave your device
• Everything is processed and stored on your phone

ScratchStack is simple, fast and fun. Stack your photos, scratch away and see what's underneath.
