The feature is called "Food Craving Panic Button"
and it is part of a weight loss app that is under development.
The feature is based on an existing feature on an Android application.
I attached first draft of specifications.
These specifications are not final, but I assume that they are detailed enough to make a work capacity estimation.
Please notice that :
1. The photos inside the app are Android's photos I should make modifications in order to adjust the UI to iPhone
2. I will add acceptance tests
I will add fine details
Whoever will take this project will not need to make UI or Graphics - I will supply UI,Graphics and Specifications
