I just have a few questions about HTML5 and one of its features that is geolocation. My group members and I are thinking to develop a social-networking IOS application that lets you check-in only if you're using a mobile phone. The core idea is that if you're at starbucks or other coffee shops having a cup of coffee and want to rate it, suggest it to your friends on FB or review other peoples' comments on the coffee/s they had, you can use the app to do all that. The IOS app sounds doable. We also want to develop a website for the application so, if you're using a PC/laptop any device other than IOS devices, it allows you to check in. But, we still are not sure what to use to develop it. I suggested the idea of using Geolocation(because it uses GoogleMaps) but then we had a look at this website which has HTML5 features demos and it changed our idea a little bit because it does not detect your exact location.
What do you guys suggest? Is there a point in developing a website for this type of project?
