About this app

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.

Very good albeit somewhat limited functionality available in the app. Having the ability to toggle on/off the zoom & pan sync is good, I like having the file name and a bit of metadata available too (also toggle on/off) What would add value: 1. Ability to select images from different file locations 2. Have the windows present side by side in landscape mode. 3. Zoom level is ok but could do with going a bit further. 4. Ability to rotate images (synced and toggled to individual)

Fantastic app! The best one of its kind. But I have an odd bug. The photo previewed on the bottom is always warmer (slight yellow tint) compared to the one on top. Please fix this issue. { Redmi Note 7 Pro user } UPDATE: I conducted a test to verify if this is a display issue from my side or something else. I used a duplicated white background and found that it looked exactly the same in my comparison. It's definitely not a display issue. It is rather a shift in white balance. Thanks! 5 STARS!

Thank you for your review. The app has identical code to display the top and bottom image, so I'm afraid this looks more like a display issue with your device. Do you also see a yellow tint on the lower half of your screen in other applications?

What's new

Implemented scoped permissions for Android 11 and higher. Fixed layout issue on display of selected images. Increased zoom level to a minimum DPI of 64. Added translations for German and Chinese.
