About ToolNeko
ToolNeko is an online tools site for quick everyday calculations, conversions, generators, and reference tools.
How tool pages are made
Each calculator page aims to show the input fields, the formula or method behind the result, practical result notes, and important limitations.
Health calculators are for everyday estimates only and do not replace medical, nutrition, or training advice.
ToolNeko favors small, focused pages over overloaded dashboards so each searcher can land directly on the tool they need.
Available health calculators
ToolNeko provides calculators for TDEE, BMR, BMI, daily calories, and body fat estimation. If a formula, source note, or page text needs correction, please report it through the contact page.
