Hi HN!
As a fitness enthusiast who struggled with the tedious and confusing process of tracking calories, I thought LLMs could offer a better way.
I've developed quickcal.chat, a web app that streamlines calorie counting to a quick text description or photo — much simpler than using apps like MyFitnessPal, in my opinion.
It recognises the food from photos or a description and logs the nutritional info. This has turned what used to be a chore into a slightly more manageable chore :)
Give it a try at https://quickcal.chat (no signup required) or through ChatGPT plugin [1] or read abit more on the landing page [2].

As it is a somewhat cornerstone of your pitch, I can't help but comment on the use case.
For the simple reason that any person's gut microbiome - which varies considerably and is the focus of intense research as too little is yet known - both consumes and modulates the processing of calories, counting calories is generally considered bad science and an entirely ineffective way to measure, guide or sustain a healthy lifestyle [1][2][3].
Personally, I think unless you're diabetic, in which case you'd anyway rely on an entirely different monitoring/ tracking system, it's just a whoefully ineffective KPI.
Most people today for example rather grossly undersupply fiber. If an app could deduce contents of calories, fiber and fat contents of a meal and track healthy composition/ supply for each, that would truly support a healthy lifestyle.
