Pros & Cons
Synchronized side-by-side comparison for fast visual judgment
Clear two-step flow: select images, then share or delete
Flexible starting point options (folder or date taken) and sort controls
Open-source with accessible GitHub repository for transparency
Limited broad-media management features compared to some gallery-focused competitors (e.g., not emphasizing videos or general file organization)
The app emphasizes photos; competitors with more general gallery/file workflows may offer broader feature sets

Description
Trying to find the best out of a series of 15 photos shot in sequence? This app shows two photos on the screen in order to compare them. Zooming and panning is synchronized, so focus and composition can easily be compared. The best photos can be selected, and the selection eventually shared. Alternatively, all photos which were NOT selected can be deleted from the device, freeing up space while keeping the best photos.
FIRST STEP - SELECT WHICH IMAGES TO COMPARE What set of images do you want to compare? Choose from:
- An image folder - A 'date taken'
SECOND STEP - CHOOSE STARTING POINT - Choose sorting options from the action menu. When transferring images from a camera to the phone, some apps will create a wrong 'date taken' timestamp. In such cases, use the 'Sort using filenames' option - Select an image as a starting point - If you want to start with two specific image, long-press the first one, then select the second one
THIRD STEP - COMPARE - Zoom / pan will synchronize between both images - Disable the zoom / pan synchronization by toggling the button in the middle between the two images - Reset both images to full view by clicking on the "center focus" button - Option to show/hide EXIF data in the action menu - Option to show light/dark image selection checkboxes in the action menu
Once the relevant images have been selected, choose "Show selection" from the action menu.
FOURTH STEP - ACTION - Take an Android 'share' action on the selected images. Beware that more targets are available if only one image is selected. - Invert your selection - Delete the selected images - Delete all the NOT selected images (depending on your selection in step 1, either in the selected folder, or from the selected 'date taken').
A word about deleting images: This will really, physically, delete the files. They're gone afterwards. BE CAREFUL TO NOT DELETE ALL YOUR PHOTOS!

Great for comparing JPEGs. No RAW support. The developer doesn't mention what file formats are supported. My album has a mix of JPEGs and RAWs. The app opens JPEGs but any RAW file that is scrolled through appears as a blank box. It can be a bit confusing since the initial "Select Image" screen displays RAW files normally and clicking them displays nothing. Adding RAW support or hiding those files in the app would be nice. Great app. Thank you, dev.

The only app that let you compare photos, great idea, works perfect
★☆☆☆☆श्री सायि -लक्ष्मण· Jul 15, 2020
File picker is a game spoiler. I have thousands images in hundreds of folders. You offer only your app's own file picker, which is very basic. Hence, finding necessary folder is difficult. Zoom isn't sufficient for images with subtle differences.

It's a good app as but this app is missing feature it doesn't let me select different folder after selecting first one because I have to compare two different which are in different folders one is edited photo and other is either raw of edited.
★☆☆☆☆marc· Dec 25, 2025
App has zero instructions. Zero interface controls outside of two picker windows. No help no action button just a page with two photos you pick one above the other. The compare photo action is just two photos open on the same page that you can look at. Nothingb
