Cowdlly Utilities

Six everyday tools in one clean app. Convert units, work out percentages and tips, generate passwords, and more — all completely offline.

Cowdlly Utilities brings six everyday tools together in one fast, clean app — and every one of them works completely offline.

No account. No internet connection. No ads. No tracking. Nothing you type ever leaves your iPhone.

WHAT'S INSIDE

Unit Converter Convert across eight categories — length, weight, temperature, area, volume, speed, time, and data storage — with instant results and a one-tap swap between units.

Percentage Calculator Four modes covering what you actually need: what is X% of Y, increase by a percentage, decrease by a percentage, and the difference between two values.

Age Calculator Pick any date and get the exact age in years, months, and days, along with total weeks, days, hours, and minutes — plus a countdown to the next birthday.

Password Generator Create strong passwords from 8 to 64 characters. Choose uppercase, lowercase, numbers, and symbols, and exclude look-alike characters when clarity matters.

Random Number Generator Draw a number from any range you set, with a running history of your previous results.

Tip Calculator Enter the bill and tip percentage to see the tip, the total, and the amount per person when splitting between friends.

BUILT TO STAY OUT OF YOUR WAY

• Star the tools you use most to keep them at the top • Recently opened tools appear automatically • Search to jump straight to the tool you need • Copy any result with a single tap • Light and dark themes, or follow your system setting

PRIVACY BY DESIGN

Cowdlly Utilities collects nothing. There are no analytics, no third-party services, and no network requests of any kind. Your preferences and history stay on your device, and deleting the app removes them completely.
