I've an idea for a smartphone game app. I want to make sure nobody has made an app like this before; how can I check that? I don't want to remake something that already exists now.

Well Jonathan has good points. But I have learned that people choose apps based on things that are not necessarily based only on popularity, but also on graphics, name, and what ever their friends tell them. So in my opinion if you believe you can do a great app, just go ahead and do it.

Unless an existing app already dominates the market such that it creates an insurmountable barrier to entry (which is rare), it doesn't matter.

Besides, if you have an idea for an app that you think is truly unique and you can't find any prior examples, it might just be a bad idea. Competition helps provide market validation.

In any case, the idea isn't important. Your success will be defined by identifying customer needs and executing, not by having a great idea.

Not sure how to respond to this. Just search for it.

Unless you have magical powers, your best bet will always be a Google search with keywords that reflect your app. Of course, whether or not someone has already made one isn't as relevant as questions like the following:

  1. Is the existing app really popular?
  2. Is the existing app really good?

If the answer to at least one of those questions is no, then you should go ahead with your app! If the answer to both, however, is yes, you should come up with a different idea.

Google google google and the appstores obviously. If you can't find anything there then go ahead and starting dev'ing! Either way if there is an app with the same type of gaming experience that doesn't mean yours won't be successful. Marketing is super important :)
