Open Tool →About Everyday Utilities
Not every useful tool fits neatly into a category. This hub collects the quick, practical utilities people search for every day: work out an exact age, check a BMI, set a countdown, test typing speed, pick a random winner, make a QR code or check a new monitor for dead pixels. They load fast, work on phones and need no app or account.
Health & Fitness calculators cover BMI, body fat, daily calories, one-rep max for strength training, pregnancy due dates and swim time conversion between pool lengths. School & Grades tools calculate GPA on different scales, convert between GPA systems, work out the grade you need on a final, and weight assignments correctly — plus classroom helpers for lesson plans, attendance and seating charts.
Everyday Calculators handle age, unit conversion, gravel and landscaping quantities, an online timer and stopwatch, and a typing speed test. Random & Fun tools include a spin-the-wheel name picker, random number, letter, animal and object generators, a city name generator, Pictionary words, a Magic 8 Ball and planning poker for agile teams.
Generators & Planners make QR codes, barcodes, calendar heatmaps and travel itineraries. Audio & Screen Recording tools compress, convert, join and trim audio files and record your screen — all locally. Screen & Monitor Tests help you check a display: dead pixel and backlight bleed tests, refresh rate and resolution checks, solid colour screens, a screen cleaner, a webcam fill light and a digital lightbox for tracing.
Frequently Asked Questions
Do I need to install anything to use these utilities?
No. Every utility runs in your web browser on desktop, tablet or phone. There is nothing to download and no account to create.
How is BMI calculated?
BMI = weight in kilograms ÷ (height in metres)². For example, 70 kg at 1.75 m gives 70 ÷ 3.0625 ≈ 22.9, which is in the healthy range of 18.5–24.9. BMI does not account for muscle mass, so the body fat calculator gives a fuller picture.
Are the random generators truly random?
They use your browser's cryptographically secure random number generator (crypto.getRandomValues), so results are unbiased and cannot be predicted — suitable for giveaways and classroom draws.
How do I check my monitor for dead pixels?
Open the Dead Pixel Test, go full screen and cycle through solid red, green, blue, white and black. A dead pixel stays black on every colour; a stuck pixel stays one colour. Try the screen cleaner tools if you are unsure whether it is dust.
Is audio processed on a server?
No. Audio compression, conversion, joining and trimming use WebAssembly in your browser, so your recordings never leave your device.
