Ray Wenderlich, author of AppVault and special developer contributor at TouchMyApps has been struck by some bad luck decisions lately. Unfortunately, none of them are his. AppVault is one of a few premium apps which does its job extremely well. But that may have been the problem. Two nights ago, AppVault was removed from the App Store at the request of one of Ray’s competitors, ALLABOUTAPPS, on the grounds that AppVault is “too similar and infringed on their copyright” in AppBox. Ray rightly points out on his blog AppVault, that according to US copyright law, ideas cannot be copied. And according to Ray, AppVault has a superior feature set to AppBox.
