TL;DR
I am shutting down DunkShot.
We never store anything at the first place. You can just delete the app and go.
If you are looking for replacement of DunkShot, try the Dribbble official app:
The long version...
Since March 26, 2018. The Dribbble v1 API was cutoff, and take many apps with it. DunkShot is one of it.
Unfortunately, it seems the v2 API removed many features that powers our app, including access of shots without user account, and method to get filtered / sorted shots list.
It does not feel worthy to rebuild an client app for the v2 platform, especially when you have to remove important features. Therefore I decided to shut it down and move on to something new.
Thank you for the long time support.
