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.

Extremely well done

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



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.
