Google and Foursquare are great. But those information are not by the merchants themselves, and they're not updated. Imagine the frustration driving all the way to a florist directed by Google, and it is out of business; or coming to a car exhaust specialist workshop listed on Foursquare and it is not open today.
We know how frustrated that could be - we experienced them all the time too. We want to solve this, by building a mobile app solely for this purpose. LocalHero stays seamlessly in your mobile phone (the size is so small you won't even realize), always at your service when you need it.
