There's a project called Tulalens (www.tulalens.org) that could use help making an android app. They're building "yelp for low income people in the developing world". They surveyed pregnant women in low income areas around Hyderabad (India), found what hospitals they went to, and asked them rate their experiences. Some women were having to pay bribes to get seen, and others reported a low quality of care. Tulalens was then able to compile the data, and go back to the women and tell them the best hospitals in the area. Many women switched as a result. For now, they want to build an app to scale up this process, and give results to users in real time. There is some open source code already. If you're interested, email priya@tulalens.org.
