Salus is an app that simplifies complex ingredient labels, providing you with essential information about what’s in your food.
Swift, apple-ocr, gpt-4, microsoft-phi-3, openai-api
Originally, we wanted to use GPT 4 or Apple's built in vision models for OCR and Microsoft's new SLM Phi-3 to scan blood pressure monitors in order to send the data into a health app, but the text detection was not accurate enough in either model to make it feasible.
For this reason we pivoted to reading and explaining nutrition labels as this is something that doesn't require such high accuracy but instead needs knowledge of different ingredients which LLM's do well.
However our biggest challenges came from building out the front-end as none of us had experience in building an app and integrating the GPT-4 API as it is not directly supported yet by OpenAI and the packages the bring support to it do not have support for the latest GPT-4 vision API.

Implementing Apple's built in vision models for OCR and Microsoft's new SLM Phi-3 quantized models so that health data never leaves the device
Expanding to other image-detection cases like reading a blood pressure monitor
Expanding to android and other platforms
