We are working on our first app and I'm responsible for the marketing. We plan to launch it in about one month and I know the importance of pre-marketing. I've created a website to get email subscribers before the launch and want to start marketing right away. But since the app isn't finished, it hasn't been submitted to the App Store yet, and won't be submitted for another two weeks. I'm not worried that someone will steal my idea if I start marketing it now (people will probably do that later anyway and it will take time for them), what I'm worried about is that someone will steal our app name by submitting some kind of app fast before us since the app name is really good. What do you think, should I be worried about this? Can there only be one app with the same name? Is there anything I can do to protect the name (it's not a registered trademark) during the two weeks before we submit it to the App Store?
