The SpringBoard prototype was built in proto.io and exported to an HTML interface. This interface can be used to navigate the prototype by clicking on buttons, clicking and dragging, and typing in text boxes.

The prototype contains a few limitations:

• 1. The prototype keeps no state other than current screen. User data is not saved, as there is no backing database.
• 2. Some functionality such as scrolling a screen or in menu options is not available.
• 3. Some UI elements such as moving value labels above sliders are not implemented fully.
• 4. Data on some charities is missing.
• 5. Some affordances like cursor changing on text input boxes or clickable elements is missing, due to the fact that this UI is designed for iOS.
