Terribly Inaccurate

Both the manual entering and AI use are horribly wrong 90% of the time and I do not see a way to edit. Despite the exact bar code being scanned and or a picture of the product it’s so off too often. For example, I had 1 Cola and it could not be convinced otherwise. Despite all my attempts it labels it as 568 Calories. So wrong. Pop has a lot but definitely not that. It’s 160. There seems to be no edit option, it does not get it right any way, and I have the latest app update. And when I try to search whatever item, I may find an option Closer to the correct amount but still very wrong

Soooo good

I have been using for 1 week and it’s changed the way I think about eating … I love it

A few bugs

I really like this app, but it’s a bit buggy:

-Time of day. The app seems to think it’s dinner time, when it’s actually around noon (I don’t see any way to add a time zone)
-AI food descriptions. Two issues I encounter are occasionally it’ll recognize the food but only give it 1 calorie, and other times it’ll ignore a part of what I type and decide the food is actually something else.
-Using a shortcut to track water doesn’t update in the app. A force quit is required before it’ll sync.

The core of the app is there, just needs some bug fixes!

AI slop ruined a good thing

I used to love this app and its simplicity, but the continued pushing of AI nonsense made it so i couldn’t return to using it. So tired of not being able to fully opt-out of LLM features that really clutter up, slow down, and dumbify all the applications i used to love and add to the environmental toll. Yet another thing that will be returning to pen and paper, i guess.
