When I message my claw "Mark that I had 825 calories for lunch today", it has marked down 825 correctly 100% of the time so far.
It shows me way fewer ads than all the popular fitness apps and loads way quicker since it doesn't have to load like 10MB of ads for me to enter one number, so it seems like a good improvement.
I do not think it's an improvement over an excel sheet, but as the average openclaw user, I would rather pay anthropic $10/day in API credits than create a google sheets document.
I do something similar with Claude Code. I say, "I ate a single serving of that Toasted Beef Ravioli that Aldi sells." Claude web searches, finds it, gets its nutrition info, then uses gspread to add it to the daily food log tab of my spreadsheet.
So much less hassle, lower activation energy needed than with MyFitnessPal.
