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!

Response from developer

Thank you for your feedback. In the latest version, the Photo Library Scan setting (Quick Scan) is enabled again. Please use the ver12.1 or later.

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.
