In the AI macro food logging world, there's really only Cal AI which estimates macros based on an image. I use cronometer personally, and it's super annoying to have to type everything in manually, so it makes sense why folks reach for something like Cal AI. However, the problem with something like Cal AI is accuracy. It's at best a guess based on the image. Macros for humans tries to be more of a traditional weigh your food, log it, etc kind of app, while updating the main interface for how users input that info into something more friendly.
I set myself a hard deadline to present a live demo at a local showcase/pitch event thing at the end of the month. I bet the procrastination will kick in hard enough to get the backend hosted with a proper database and a bit more UI polish running on my phone. :-)
