Compare photos side-by-side, and eventually share the best ones

You can select the best shots, share them, or delete the rest to reclaim storage, all while benefiting from an open-source workflow. With 100,000+ total and 640 downloads in the last 30 days, the app shows steady interest from photographers.
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!

Does exactly what it's supposed to do. A rarity these days! Thanks for making this!

Does exactly what it says and is simple to use. Having a grid to help align each photo would be nice. Also, would be a cool feature to have a mode to be able to "flip" between photos full screen (see photo A, and when you touch the screen you see photo B).
★★★★★Mark Balazo· Dec 30, 2023
Brilliant app! It does what it's supposed to, compare images and the sync pan and Zoom is a welcome feature.
★★★★★Shubham Meena· Oct 21, 2023
Great app to compare 2 photos side by side. I personally use it to compare shots from either 2 phones or 2 different GCams from the same phone.

Limited access to files. I want to access and compare images from a number of sources. This app only seems able to access local files. I can see no way to access files on my Google Drive or Google photos.

I will give it 5 star if only you could fix the slow reload while having a lot of photo in one folder. For my case it takes full 1 minutes to load 12k images that I have in my folder. Also refreshing in the current folder should be added. Every time I take a picture then I go to the app I have to go back to main screen and reload so new pictures appear. Also, please add file size at the end of exif Thank you <3

The app does not provide a way to search for & select a folder or images by name, so as is, it is not useful for me
