Developers are reporting that their apps are being rejected from Google Play or iTunes because they are trying to convince users that they are related to Flappy Bird. Mind Juice Media's Ken Carpenter tweeted that his game, Flappy Dragon, was rejected by Apple because his app name 'attempts to leverage a popular app."
Several other developers responded that they had received similar messages in response to their submissions. Carpenter was told by Apple not to use 'irrelevant, misleading, or excessive keywords in apps descriptions, titles, or metadata." He was able to get his game approved on Google Play by renaming it as Derpy Dragon.
An Apple spokesperson said that the company isn't simply rejecting games with "flappy" in the name, but instead titles that are clearly trying to trick customers, making them think their app is replacing or associated with the original. Google has not commented on the matter yet.
There are still ways and means of getting your Flappy Bird fix, but you may have to work that little bit harder to find the alternatives.
