Reason I bought new iPad
Tried many iOS apps and Windows apps on a Surface pro. This single app is the reason I bought my new iPad. Nothing came close to the ease of use, speed, features, intuitive UI, support, etc.
Had over 10,000 photos I needed to cull quickly and this app fit the task perfectly. 1 very cool feature is the ability to flash full screen images back-and-forth to compare very minor detail. I had 1,000’s of whale photos with very minor differences in details and focus which made this feature alone well worth the price.

Can’t view any images…single or twin
The app is saying there are no images to view
BEST APP for side by side comparison photos
I’ve tried so many apps for side by side before and after photo comparisons and this is definitely the best and easiest to use. Development team is also SUPER responsive!
Having problems
App worked great for years but within the last few months I’ve been getting a “photos aren’t available locally” error every other time I try to open an image. I checked my Privacy settings as was suggested in a previous reply and Twinviewer was already set to All Photos. Reinstalling didn’t help, only temporary fix I’ve found is that sometimes resetting the devices works.

great app no subscription fee
This is a perfect app to combine multiple photos for a side-by-side comparison etc. The best part is I don’t have to pay a weekly or monthly subscription for something that I only use like once or twice a year which is why I never had kept an app to do this before, past the trial period.
I didn’t know this until after I bought this app but there’s also a different version which is more expensive and does quad photo comparisons. Had I known before,I might’ve purchased that one instead just to give me a more options for the future.

Need more instructions. I purchased it and nothing happens
Used this app once and it worked once. Today nothing would work, so I upgraded and still nothing happens. No choices to choose from. Cannot open my photos to choose anything. Think there might be special instruction somewhere, but where? What is wrong? Would like it to work. Tell me what needs to be done to make it work? If it is broken then please refund my my money. Thank you

Best Before and After app
I am a aesthetician and I use this app for my Before and After pictures!
Still using it today
It pairs nicely with Procreate when referencing images.
Excellent
I’ve been using the full version now for a few years and have found it excellent especially for comparing visual and / or metadata details on almost identical images, prior to Twin Viewer I tried several other similar apps but for me this one was the best, I haven’t felt the need to look any further.

The perfect app that connects no data about you!
I am going to buy this, not because I need the extra features but it’s everything indeed and the dev actually doesn’t collect your life story (ie personal data)
An excellent tool
This is an excellent app. Allows me to compare and zoom two photos - and the zoom can be locked or unlocked to zoom together or an individual image. Make sure you allow access to all your photos at the start. Easy to use, a great find! It is easy to select which photos you want and you have access to choose photos from your Recents or any other album on your phone. Love it, thank you!

Great Viewer
I was looking for an app to open my video game app to play on my card board viewer. *box app allows viewing on my iOS devices now, but no way to split . I tested this app with a screen shot and applied it to both screens , placing my phone in my VR device and it worked perfectly once my eyes adjusted. This is the closest thing I found. If I could open the app instead of a photo and mirror the other side it would allow me to view whatever I want on a portable viewing system anywhere anytime, sitting laying or standing. Without spending $600 on a proprietary VR and AR devices. If the developers can make that I would purchase it. This app does what it says , but can be so much more. Thanks.

Minor issues
Would be great if Recently Deleted were an available folder on the menu, seeing as more and more apps have managed to implement this option.
Otherwise, best tool for comparing images that I've used; more convenient and quicker than using the layer method in the typical photo editor.
Update: the below is now fixed, thanks!
I noticed (I believe within the last few versions) that the iOS status bar at the top (containing network info, time, battery and other indicators) no longer disappears when attempting to view an image full-screen in the app. This makes image comparisons more difficult or less convenient in some situations (e.g. screenshots taken in the app of zoomed-in portions of an image pair). It would be appreciated if this issue could be fixed by either hiding the status bar and ensuring the image is truly full-screen, or at least giving the option to completely hide it.

New version doesnt access my photos
The app has worked fine for many years but now it won’t access all my photos. It only gives me the option to select ‘smart album’ that only has a few most recent photos in it. So now the app doesnt function. Very frustrating especially as i have the paid version. Help appreciated
Odd Problem
I like the app but I can’t find any way to upgrade to the paid version. That’s a problem I haven’t run across before. Can you please fix it? Thank you.
UPDATE: I got a response from the developer explaining how to address this problem. Now that I was able to upgrade, I’m happy to give this app five stars.

Love it
This is an awesome app. Thank you developers!
Excellent
I use this to compare in-progress paintings and reference photos. I am so happy I found this.
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!

Twin Viewer
I found this app yesterday, exactly what I was wanted, and bought the full version straightaway ! A excellent app and very easy to use
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！
