Picture This is a game that encourages people to explore their environment and go places they have not gone before. The game consists of challenges where the challenger takes a picture at a specific location and sends it to one or multiple other users, who have downloaded the app and are currently in the challenger's Google+ circles. Given a hint regarding where the challenge picture was taken, the challenged user(s) must venture out to find the place and reply with their own picture, matching the original as closely as possible. This response can either be approved or declined by the challenger. If the response is approved, the challenged user wins the challenge and is rewarded with points; if the response is declined, the challenged user can try again, until someone wins the challenge. Each user's points are tracked using Google Games, which also grants them achievements based on specific actions. They can access their achievements and the leaderboard form a side tab on the homepage.

The app has five screens: Login, using Google+; Challenges Home, where the user can see the challenges they have sent and received; View Challenge, where the user can view the challenges they have received; View Response, where the user can see the responses to the challenge they have issued; Create Challenge, where the user can create a challenge; and Challenge Map, where the user can view a circle around the location where the picture was taken. Parse is used to store and access the data. Material Design is used to make the layout more appealing and user-friendly. Embedded Google maps are used to display a radius around the location where the picture was taken. Users get push notifications when they receive a challenge or a response and when their responses are accepted or declined.
