Where to begin… Before there are enough stores and locations added to that app, it will take ages. Google paid videographers to drive around and make the maps, that’s why it worked. The other problem with the campaign, like with most app are the pledges. For $500, all you will get is a mug, a T-Shirt and a thank you video. Finally, stores like Home Depot and other supermarkets are consistently moving stuff around, do you think they will update a third-party app, all the time?
