Great little app. (Update)

I’m a photographer and retoucher. So it’s nice to be able to compare the original photo with the retouched photo.

After the response from the developer I found the exact feature I was looking for. I missed the instruction in the beginning! My mistake! Being able to tap to quickly switch back and forth between the photos so I can easily see what has been changed. Perfect! Paid for the full version after finding this out!

I guess another neat feature would be if there was also an option to have a slider to compare photos. Where you could slide to your finger back and forth and reveal the second image. Similar to the app “Photo Compare.” This would be a really cool way to compare images.

But the app is already wonderful! This is exactly what I’ve been looking for! ありがとうございました!素敵なアップです!

Thank you for your feedback. I'm sorry for the insufficient usage information. The app already has the function. Double-tap either one of photos to see it on full screen. Tap it to switch. Long-press to switch quickly. You can see more help in Information page. I hope it would suit your needs. ;)

Great support from developer!

First, the app is terrific. I use it to compare images that can be used as examples that show complementary or dissonate differences for teaching. The ability to save as a combined image with captions is just what I needed. And who knows, I could use it to create the next “woman screaming at the cat” meme.
Second, the developer is super-responsive. I emailed a suggestion about Sort Order and in less than 3 days, the app was updated!

Best tool for comparing images

Best tool for comparing images that I've used; more convenient and quicker than using the layer method in the typical photo editor. Would be perfect if Recently Deleted were an available folder on the menu but given that most apps don't have that, I'm not complaining! Thanks so much!

Thank you for your encouraging comments and I'm sorry I could not meet all your requests.
