Building Grocery Mentor, launching on PH Sept 10

Hey everyone, launching Grocery Mentor on Product Hunt this Thursday (Sept 10). It's 22 free calculators for grocery budgeting, unit pricing, bulk buying math, meal planning, shopping lists and food waste tracking. No sign up, works in Spanish too, built solo.

Would love early feedback before launch day, especially on which calculator seems most useful and what feels missing. Happy to answer any questions here.
