Sadly it seems that the rather excellent Flickr Booth for Windows Phone, along with JC Mobile Solutions' other apps, has been withdrawn from the Windows Phone Store. The popular Flickr client still works fine on existing installations, but it's no longer in the Store for re-installing on a new device, sadly. All avenues of enquiry have drawn a blank, the developer seems to have unpublished everything and withdrawn (temporarily?) from the mobile scene. All very odd.
Flickr Booth, which started life as 2flicka, in action recently...
I'd surmise that the developer has a new customer or jon that prohibits publication of these applications. It's tempting to wonder if Yahoo/Flickr itself has hired him or her to take the client to the next level, but that's pure guesswork.
Flickr Central is clearly fully featured, but the occasional blind alley in the workflow, together with occasional lag and unexplained pauses (for example, try backing out of the app and then tapping to go back into it again!!) do reinforce the impression that the application is in need of a little attention from the developer for 2015. Hopefully it'll get it.
Can you shed any light on Flickr Booth's disappearance?
