Ask HN: Need feedback on a project idea

Hi,

I have an idea to build an iphone app. Main idea of the app is to provide information to the users based on your current location. This information is about the nearby places. It can comprise of historic significants, reviews and any intersting facts.

One use case would for tourists to get the required information. Also, if possible I can add a virtual tour which will guide the tourist to see all the important things on that spot.

Please let me know what you think.

thanks.
