Everyday Tools Hub is a free collection of online calculators and utilities for the small, practical questions that come up every day. The site is operated by KunStudio, an independent studio that builds simple, privacy-respecting web tools.
Our Mission
Most everyday calculations - a tip, a BMI, the days between two dates, a discount, a GPA - should take seconds and shouldn't cost your privacy. Everyday Tools Hub gathers these common tools in one clean, fast place so you can get an answer instantly, without installing anything or creating an account.
What We Offer
- Health and date tools: BMI, age, date duration, and time duration calculators
- Money and number tools: tip, discount, and percentage calculators
- Study and text tools: GPA calculator and a live word and character counter
- Utilities: unit converter, password generator, and random number generator
How We Build
Each tool is a single lightweight page that loads instantly and runs entirely in your browser. The values you enter are processed on your own device and are never uploaded to or stored on our servers. There are no accounts and no required registration. The site is built mobile-first, so it works on phones, tablets, and desktops.
Accuracy and Independence
Our tools follow standard, widely accepted formulas, and we test them for correctness. Even so, results are provided for general information only and are not professional, medical, financial, or legal advice. Everyday Tools Hub is independent and not affiliated with any third party whose service or formula it references.
