I am so impressed by how comprehensive your research seems to be. You did a really nice job Swapna!
While I was reading through your creative brief, I too thought of additional features that could be added to the app in one of it's phases to make it more inclusive to people of a variety of socioeconomic backgrounds. Often, location can be a potential barrier to living a healthy lifestyle and eating healthy food. Some neighborhoods lack options when it comes to grocery and health food stores, which can make it especially difficult for people who don't have easy access to public transportation. Others may lack large chain grocery stores, and instead have smaller marts that may not show up on the apps radar. Could the location tracking feature be expanded to include small local stores, neighborhood bodegas, and farmer's markets? Maybe allowing users to add and rate stores based on the quality and variety of healthy food available would ensure that the map is always up-to-date.
Also, the perception that healthy foods are more expensive and cost-prohibitive is another barrier that may influence a person's eating habits. I love that you included the option to enter a budget within the app. I think creating a cost comparison feature could take it to the next level (why not compare that $2 donut with it's equivalent in fruits and veggies?).
Maybe it would even be helpful to add a barcode scanning feature for app users to take advantage of while they are shopping in the grocery store! I am noticing that this has become a pretty common feature of most calorie-counting apps. It could make it easier to compare unhealthy snacks with healthier options on the spot. Just some food for thought :)
