JoeGuru ,

Extremely well done

When the other app went exorbitant, switched to this one and never looked back.

Ldangelo.md ,

Was 5* for me…now 3*.

As a dicom reader the App is awesome for what it does. Not that many options in the App Store that can match it. But I work most of the time in places where sometimes the conection is not that good and I bring most of the time my IPad and each time I open the app and I don’t have a conection to add a file the message verifying the subscription pops up. I am sorry for this score but as a person that paid for the full year and really likes your app having it failing when it need it most just because I don’t have a internet conection really pisses me off.

Developer Response ,

Thank you for your feedback. The app should work offline as well. If you are experiencing issues please contact our support team. This is how we can help you. Leaving a comment in the app review section in the AppStore really doesn’t help us understand the issue you are facing.



Images look great. Scrolling on thin sections on CTs was a little slow even on fast srolling setting. A scroll bar would be nice. There is no progress bar that I could find when retrieving studies so it feels unresponsive when retrieving studies with many images.
