Project Budget (USD)
$500 - $1000

Project Description:
I need an iPhone app to be developed for energy monitoring. Users with solar panels should be able to monitor their electricity production, consumption and so-called self consumption. The description below is the release 1 of the app.
The users of this app form a community. In a later I plan to extend this app with community information and interaction between participants of the community.
I ask you to bid on release 1.

Release 1
The app will have 6 screens, with basic navigation from home screens to subscreens and vice versa.
1 Splash screen, logo + login
2 Home Screen, main menu
3 Electricity usage overview, historical data (area graphs, bar graphs)
4 Live electricity usage, realtime data (graphs)
5 Costs (tables)
6 Settings

Important for the app is good graphical representation with good performance. Usage of a graphical library is recommended.
Data are provided via a web-service interface. This interface is implemented as a stateless RESTful webservice and supports JSON and XML. Interface specification will be provided.

The app shall be a native IOS app, suitable for iPhone: 4, 4S, and 5. Look & feel based on Apple’s UI controls, similar to the standard apps (buttons, date selector etc.)

Furthermore, I need to have integration with social media, such that an user can post data to social media, and, in future, use social media to build the community.

- Working App, according to the description above
- Source code and IP rights (exclusive)
- App ready for submitting to the AppStore (I will take care of submitting it to the app store)
- Short design description (2 pages)

Way of working
I will work with milestones for intermediate deliveries; I expect an agile, flexible approach
