Challenge Description:

For this challenge we are looking for you to help us come up with screen designs for a mobile version of the existing citycheckbook web app:  This existing web app is for one of Socrata’s clients, the City of Davenport, IA.  The goal for this challenge is to help convert the existing citycheckbook application to mobile screen designs that can be used to build a responsive, HTML5 mobile app.

Please keep in mind that Socrata would like to have the underlying mobile design and structure be portable to as many other clients (e.g. other cities or orgs) as possible. When you design for this client, City of Davenport, consider Socrata first but also think about ways to bring in the client's brand / look and feel into the design in a way that Socrata can repeat this with other cities or orgs.

Project Overview:

The client for this project is Socrata, the world leader in cloud solutions for open data and data driven governments (  They help their clients, such as the City of Davenport, make government data available to the public.  

Application Requirements:

1) For this challenge you will need to design a mobile version of the existing citycheckbook:

2) The Mobile HTML5 design and structure should be portable to as many other clients and/or prospects as possible.  In other words, when you design for this client, City of Davenport, consider Socrata first but also think about ways to bring in the client's brand, look and feel into the design in a way that Socrata can repeat this with other cities or orgs. 

Challenge Requirements:

Screen Size:
- Required: The target device to focus on is iPhone 5 Portrait (retina): 640px width
- The mobile app being built will eventually be for a responsive website where iOS and Android are the target platforms.  While iPhone 5 is the target for this challenge, please consider how your design will scale up for larger screen sizes.
- Please feel free to include screens in Landscape if you feel this orientation will work better for specific screens / functionality.

Please make sure all pages have the correct flow, use file numbering (00, 01, 02, 03) to capture this. Your submission should include the following screens and functionality:

1) Splash/Loading Screen
- Consistent with City Brand

2) Landing Page
- Socrata Standards used for every city

3) Main Graph Visualization, Alternate Visualization
- Socrata Standards used for every city.

4) “Drill In” Graph and Table
- Use this case to focus on how to represent this on a mobile device ­ Use case details included below.­ To search for City payroll information, please click here.

5) "Check" Screen
- When you drill all the way down to a payment you see a “check” modal dialog. This shows the actual amount spent on town expenses. This is why they call it the checkbook! 
- Screen Idea: Include who spent what and why.  Think as a citizen - how would you want your tax dollars spent, and how you would use this information on a mobile device?
- See Check Screen (attached) for more details.

Use Cases:
- Coming from City of Davenport
- According to the Financial Analyst at Davenport City, the most common use case is someone looking up the salary of a city employee.
- The list of salaries is accessed from a link on the landing page, which takes you here:
- In any case, the "salary search" is a good use case because:
   (a) we have some customer data to back it up and
   (b) it presents a challenge to render on a mobile device, (the PC view includes search, list sorting, various visualizations (see below)).
   (c) Visual ­ See Attached

­ This will eventually be a responsive website and iOS and Android are the target platforms.
- Please follow the look-and-feel (colors, fonts, etc.) of the existing citycheckbook web app (  Your screen designs for the mobile app should be similar to this.  We are open to some creative choices here as long as it isn't too different.
- Use the City of Davenport's current city site as rough style guide ( for their branding.  Keep this in mind - as Socrata adds other cities / clients­ how can this design be used at other cities?  Take current branding and style, and meld into Socrata CheckBook.
- Your design should be for a mobile app screen resolution (iOS and Android). Make sure you create graphics in “shape” format, so when they are resized for retina versions the graphics still look sharp!
