Prototype II

This is the second prototype. Its purpose is to implement the improvements discovered from the surveys contacted.

Goals:

1. The ability to perform keyword searches.
2. Provide the shopping list to view all items that have been selected
3. Use a uniform button size to improve consistency
4. Use larger text
5. The buttons were too close to each other so sometimes people would press the wrong button. This is now fixed.
6. Increased screen size
