Have you verified that these are mostly accurate?
Initially I verified against labels by eating the serving size precisely. Then, I switched to weighing and doing the math on random days or meals.
For some items I would tell it the calories and macros and it would remember (a pb spoon is a common treat around my house).
It's good.
But like all food journalling the benefits are not so much having macro balances or tallies, its in making you aware and making you think about what you're eating. That alone takes you out of autopilot and lets you eat better.
It's just bad at math. So I would ask it to output a json struct for each day, that I could inspect by sight, then I'd save that and had a python script to actually tally.
I had predictive analytics and the whole 9 yards. Maybe I should have started a business! https://jodavaho.io/tags/diet.html
You are providing accurate info to an LLM and it is assisting you with information processing.
These apps are trying to just take a picture of arbitrary food and just trusting a neural network to be magical and tell you the macros in the food from a photo.
Honestly curious if that would have improved the author's experience.
It's local-first so you control this sensitive information. It features easy reuse and exercise tracking.
I exploit my "frugality" neuroses by treating calories as an expense.

There's a lot of questions about the nutritional content of food which you can't answer just by looking at a photo, like "is that a glass of whole milk or non-fat", or "are those vegetables glossy because they're damp or because they're covered in butter". No amount of AI magic is going to solve that.
We are not shipping camera functionality yet. But our concept is to not necessarily guarantee the accuracy of portions but to make lookup easier.
We also spent the time to get the AI integrated with a verified database. This made our results far more accurate.
We tended to find that without the lookup the calories and macros would be generally correct. The math was usually within a margin of error of 5%. This was acceptable except that… there was no micronutrient values and you couldn’t really adjust the portions at all. The system just dumps the macros and while you can halve something… the user experience isn’t great.
Ultimately, if you want precision: manual entry is the only way to go. I feel like out approach will end up being very great once we work out the kinks. Our search isn’t spectacular and as a team we are learning a lot of about prompt engineering and how to make best use of the AI.
Macrofactor is also the only app I've seen that actually estimates your underlying metabolic rate and adjusts accordingly. It predates the recent AI surge, and seems to have a team that's studied nutrition science behind it.

These apps with graphs are just selling you a sense of control, of compulsive metric driven decision making. Its partly the consumers’ own fault – many people won’t care even if they knew. But it’s also predatory by the companies. It’s consumer tech in a nutshell: put a pretty but shitty app on the App Store, spend 80% on marketing, show ads in the free tier, sell overpriced premium offerings to those who are careless with money, rinse and repeat. I follow some subreddits and groups for ”entrepreneurs” and it’s just like this.

I used calorie counter apps before and they helped me lose weight (by mostly educating me what to eat/avoid). With these apps, I feel like the core premise - counting calories - isn’t even working and they’re selling people hopes and dreams. That’s danger territory.
