Ratings and Reviews

Fantastic App


Clearly one needs the DXO One camera to make this App functional.

I bought the DXO One camera and find that I now that although I have three cameras in total- the one I take out most of all is the DXO One. The combination of an SLR quality camera body and the iPhone as a controller and viewfinder is an awesome combo!

The App makes it very easy to take truly high quality pictures.

A great start


A nicely laid out app, I do find the app hangs on numerous occasions and a disconnect and relaunch is required to get it working again but I'm sure they will iron this niggle out shortly.

I've just received a Lubecube which I had hoped I could use with the app but unfortunately not. I'm hoping DXO and Lumecube could do a bit collaboration - now that would be a great combo.

Nice looking app... But crashes too often

PM Extraordinaire

App is aesthetically pleasing - but functionally problematic. Every time I have gone to take photos with the DXO camera, I need to close down and start the app 3-4 times before it works. If this issue can be stabilised and fixed, the app will be stellar.
