Recipe Radar is a React Native app that suggests recipes to you based on the items you have in your fridge/pantry. Click here to see a video demo.

After buying groceries, you can use our app to take a photo of your receipt. The app will parse out the items in your receipt and save them to Google FireStore. It will then recommend recipes you can make based on the ingredients you have. You can always manage your list of ingredients using the app's interface.
The front-end was built using React Native. It uses axios to query the recipe API and uses Google Firebase to store the user's list of ingredients.
On the back-end, we have a Flask server that receives the recipe image from the front-end through ngrok. It then sends the image of the receipt to Google Cloud Vision to get the text extracted. We then post-process the data we receive to filter out any unwanted noise.
Front-end: Alice Cai & Lucas Budz
Back-end: Andy Jiang & Deep Pandya
One of the challenges we ran into was deploying our Flask server to Google App Engine. We found that it was not possible to write into Google App Engine storage; instead, we had to write into Firestore and have that interact with Google App Engine.
On the frontend, we had trouble designing the UI to be responsive across platforms, especially since we were relatively inexperienced with React Native development. We also had trouble finding a recipe API that suited our needs and had sufficient documentation.
