Story

Yelp, Google, Apple Maps, you name it, every mapping/places application only brings YOU to places. It shows you nearby areas and lets you find places for you to go.

OverThere aims to place a similar service on your wrist - but yet completely different. We aim to bring places to YOU. You don't have to search for "Taco Bell" or "Bank Of America". Simply choose a category and be brought results! Based off of Google Maps, it puts easily readable information on your wrist, as well as the option to favorite a location. You can choose to "Go!" to a location, setting it as a destination. When you arrive, simply flex your wrist! This will let you check in and clear this destination, allowing you to save a location to go to at any point you wish. Using the powerful Google Places API, anything is possible!

Additionally, for businesses, OverThere packs in OverHere. OverHere allows clients (once connected to your wireless network, because that's the first thing everyone does at a restaurant!) to set a two part ID (you must provide this, it is the x and y numbers in 192.168.x.y, the IP of the LinkIt device). This two part ID allows them to "Get Information", immediately sending a get request to a web server on the LinkIt Device. The LinkIt Device returns JSON data incorporating information provided by the business. For example, if I own a store with a LinkIt Device on 192.168.8.78, then the client uses the numbers 8 and 78 in the Pebble app. Once they click Get Information, I can even send them a Menu with all my products listed on it.

OverThere saves your destination and favorites, allowing data to be interfaced multiple times. You can add up to 20 favorited locations!
