Inspiration

Many of my close friends and my parents have suffered with various allergies ranging from food to general allergies in the air. Additionally, often we come across various foods that we may or may assume not to have any allergens in them however, unexpectedly, this assumption can result in a very serious sitatuation quickly. On a less extreme note, pollen and other allergies from pollution can result in irritation throughout the day, really disturbing many people. Due to the lack of applications which is able to detect the ingredients of foods and the allergens in the air, I felt obligated to create an application and my app development skills in order to create an app beneficial to those who have suffered and unfortunately resulted in extreme situations due to simple mistakes. As a result, I have created RADAR helping users detect food and air allergens based on preferences and locations.

What it does

The app consists of three different sections:

The main part of the app is the Food Allergen Detector.

You are prompted to select what your food allergen preferences are such as milk allergies, peanut allergies and more. After that, you are able to either input manually, by typing, a name of the food and see whether it has any of your allergy foods that you specificied in the beginning. You can also press the full ingredients button to view the full list of ingredients. The second part of the app is the air allergen detector:

In this part of the app, using your location, the app is able to find the local Air Quality index based on your location, In addition to that, it is able to show you a reference point such as good, bad or great in terms of air quality. There are also other options to visualize this data for pollen and pollution as well. You are able to press on a heat map and it will visually (Intuitively red being poor, and green being good) in terms of air quality for the air quality heat map and same in terms of pollen concentration for the pollen heat map.

The last part of this app is the procedures tab where you are able to view various procedures regarding how to tackle various situations such as detecting where you have an allergy or not, what to do when suffering or someone in front of you is suffering an allergic reaction. These various links allow the user quickly to access resource and act quickly.

How I built it

I built this app using Native Base UI Library, react-navigation, Breezometer Pollen, AQI and Heatmap APIS, and the Nutritionix API to reference the ingredients based on the name of the item.

For the first section, the item is searched with in the Nutritionix API in order to see if the food has the allergens I chose. It uses Native Base UI elements.

For the second sections, the Pollen API, AQI Index and Heatmap's data was all created using Breezometer's Heatmap, Pollen and AQI Apis which I was able to retrieve the information from and then displayed. I also use expo permission to retrieve the location of the user.

For the last part of the app, it is a varied of links which I use Native Base library to create the ui for.

What's next for RADAR

I hope to release this application into the App Store sometime in the future in order to help those around and allergic people themselves prevent, and raise awareness about allergies in general.
