Nawtch

Nawtch is a free calorie, macro, and weight tracker built for people who don't want to create an account just to log a meal. Add foods manually or by barcode scan, track calories, macros, and cost per serving, monitor your weight over time, and build custom workout programs and exercises. Everything is stored locally in your browser via IndexedDB, never on a server. View your full history with exportable data (CSV or JSON).

Beyond core tracking, Nawtch now includes a growing set of evidence-based calculators (TDEE, BMR, macros, body fat %, BMI, ideal weight, one-rep max, VO2 max, waist-to-height ratio, walking calories, protein, sleep, and water), each citing the actual formula or study it's based on. A Diets section covers 15 popular eating patterns with honest, cited evidence for each, plus a Diet Arena tool that lets you pick any two diets and compare them side by side across the same categories, no verdict on which is "best."

The Supplements section covers common supplements and FDA-approved medications with real research and sourcing, and includes a Supplement Tracker for logging daily doses against a target, same local-only storage as everything else. Other tools include a Bowl Builder for building a meal item by item with live calorie and macro totals, and a Grocery Budget Calculator for planning what your groceries actually cost based on how you really consume them, not a generic per-person estimate.
