Unlike most existing apps that only track what you eat, my app helps you figure out how much to eat to hit your target macros. Initially, I had created some Python scripts that worked well, but I found them inconvenient to use as I needed to be near a computer, edit the script and manually add ingredients to a dictionary. To make it more user-friendly/faster, I re-wrote it as a web app in Rust for the backend and integrated a free food database.
Now, I can quickly and easily add a list of ingredients I have at home from my phone and hit calculate.
Currently, I'm the only user, and the tool is designed entirely for my needs. However, I think it could be useful for others looking to plan their meals and eat healthier, which is why I host publically. If I were to build it for general public use, I would need to relax the constraints to allow flexibility on how close it can match your targets. I would also want to add more food sources, maybe the USDA database, but since I'm not in the US, a lot of the foods won't be relevant to me. Maybe if I get the time i'll work on it but for now it works perfectly for me.
