About LifeToolbox

LifeToolbox is a collection of free online tools for everyday life — tip calculators, BMI, unit converters, date tools, and more. Every calculation runs entirely in your browser. We never upload your data to our servers.

We pair simple, mobile-friendly calculators with practical guides so you can get answers fast — at a restaurant, while shopping, or planning your day.
